Thanks guys Will post a full tutorial shortly and a writeup on the technical side of course.

Long awaited update is now here, a lots changed. Grab it from the downloader or my GitHub. Changelog Download prebuilt version

Hi guys. Happy to see people are interested in this. The basic situation as of now is: I'm looking to producing and selling these, but I'm seeing that people are buying up loads of these chips so might give up on that If MakeMHz sells this hardware, I will see if my software works for it too The current state is that I haven't been able to get the memory running at full speed, so performance suffers 256MB is the absolute maximum as far as I know I'm going to release all the design files, software, patchers, etc. shortly Yeah I know this is useless but it's just for fun

It has long been thought that the Xyclops chip, which contains the BIOS on a v1.6 motherboard, is not flashable. However I recently discovered it has a serial port with a variety of interesting commands. It supports dumping the BIOS as well as the Intel 8051 code that runs the SMC functions of the chip. And just like the other Xbox versions that have the TSOP flash, we can reprogram the BIOS on the v1.6. In one way this mod is better than your typical TSOP flash because it's easy to recover from if you screw it up. The serial port will still be available. Tutorial Required items: 3.3V USB to UART adapter. You can find many of these available online at very low prices. See if you can get one that has a TX resistor value lower than 1k because the Xbox's RX has a 1k pulldown. v1.6 Xbox with Xyclops marked A-A02. A-B01 is not supported. Soldering iron Either the GUI for Windows or the command-line script: GUI Download XycloModGUI by OGXLABS https://www.ogxlabs.com/xyclomodgui Script Python installed on your PC Download the script https://github.com/Prehistoricman/Xbox_SMC/blob/master/Xyclops/xyclops_flasher.py A 256KiB BIOS bin file Steps: Connect your USB to UART adapter to the Xbox. This can be done either by connecting to the AV port, or by opening the Xbox and using internal connections. Internal connections Xyclops pin 29 is DEBUG. Wire it to the 3.3V standby voltage. Xyclops pin 64 is TXD. Wire it to the adapter's RX pin. Either: Near Xyclops: OR under the AV port: Xyclops pin 63 is RXD. Wire it to the adapter's TX pin. Either: Top side, near AV port: OR under the AV port: Connect ground to the adapter's GND pin. You can use the xbox metal case, any screw holding the motherboard down, or pin 2 of the LPC header (see pin layout here). AV cable - not advisable! See AV plug diagram here https://xboxdevwiki.net/AV_Cables Pin 5 is DEBUG. Wire this to 3.3V. Pin 18 is TXD. Wire this to the adapter's RX pin. Pin 6 is RXD. Wire this to the adapter's TX pin. Remove resistors below the AV port: R5M3, R4M10. This will affect the video mode recognition and can prevent normal display, so they should be replaced after the mod is complete. Connect any ground pin (such as pin 6, 7, or to the adapter's GND pin. If you cut LFRAME to do a modchip install, you will have to reconnect it. Plug in the USB. It's better to do this before powering on the Xbox Plug in the Xbox. It can be left in standby. Identify what serial port your adapter has. On Windows you can expect it to something like COM5. GUI method: Run the XycloModGUI exe Select the COM port if you know it Click the Connect to Xyclops button Click Browse... to select the BIOS to flash Click Start Selected Operation to flash the BIOS to your Xbox. It should take about 6 minutes Script method: Install Python 3 if you haven't got it already Open cmd, powershell, bash, or whatever the terminal is on your PC. Execute the script by writing python xyclops_flasher.py your_bios.bin COM5 to the terminal, replacing your_bios.bin with the path to your BIOS file, and COM5 with your serial port. Press enter Follow the on-screen text. It should say Xyclops communication established and ask if you want to erase the flash. Once the connection has been made, or even attempted, you may be unable to turn on or off the Xbox. That's normal. The SMC gets frozen while the serial is active. The Xyclops can get upset and stop responding sometimes. If you can't get communication, try unplugging the Xbox for 10 seconds. If you get erase timeout, make sure you made the GND connection. If you can't get communication, then your serial adapter might have too much internal resistance. Identify its TX resistor and reduce it to ~500 ohms. The flashing process takes about 2 minutes, and the verification (if you want to do it) takes another 2 minutes. If you want to verify again, use the -v option: python xyclops_flasher.py your_bios.bin COM5 -v The Xbox power button should work again, so try turning it on. If you get video issues (like greyscale video) and you removed two resistors in step 1.2.5, you will need to place the resistors back. Disconnect the DEBUG wire for enhanced stability. The Xyclops will freeze whenever it sees any activity on the RX pin. FAQ Can we use a BIOS bigger than 256KiB? Not on a retail xbox. Some rare devkits may be able to do 512KiB but I have not confirmed that. I ran the script and my Xbox won't turn on! Yes, the SMC will freeze when it receives serial communication. The script should resolve that if it exits successfully, so I must assume it failed. You can unplug your Xbox for 10 seconds and plug it back in to reset and try again. Can this be done via a software method? Not to my knowledge, but it is rumoured to have been discovered. Technically the answer is yes, but it involves using the serial first and then reprogramming the SMC (advanced). What else can it do? The Xyclops serial port is able to do a lot of low-level actions on the SMC. For example, it can 'press' the front panel buttons, change fan speed, change LED colours. It can also potentially do some hacky things such as spoofing the video cable mode, or bypassing the boot challenge (FRAG). We are also able to re-program the SMC which could lead to some more advanced mods for specific and niche purposes. Through the AV port??? Yeah I know right? We can't be sure why Microsoft made it this way. It's too slow for factory programming AND there's those resistors preventing it on retail units. It could definitely have expedited the development process of Xyclops, but that doesn't explain why it was left present in the retail motherboard.

I have been working very, very hard over the last 5 months. I have wanted to create a modchip ever since the days of the Xecuter 3. This does not match that level of mod... However, I have tried to do the best job I can at creating something unique and special. This is the BSX Nova. It encompasses pretty much the entire ModXO pinout and I don't think anything is missing. It should lay a pretty good foundation for what is currently supported and what is planned for the future. There is the Display and Expansion I2C/SPI ports, Motherboard I2C (for things like plugging in HDMI mods and programming with ElpisHD/Cerbios), RGB, UART, and the USB header for the front panel ad future add-ons, whichever works for you. I have a few other mods that are all basically finished and will officially announce them when I plan to go to production with them. I realized that people may not want to spend so much on a flagship modchip, so I thought maybe a cut down version would be a good idea for those not wanting to spend so much. This is the BSX Mini. Please forgive the flux mess; It's stuck in a console right now and I don't wanna remove it. I removed the SD-Card, I2C expansion (still has the Display port) and onboard USB and bootsel button. This allowed me to cut it down to an INCREDIBLY small size and will allow me to sell it at a cheaper price than the Nova. I did give it the Amber eyes though, so I could replace those features with something cool. Both chips feature a dupont docket D0 wire, which will allow for simple install and removal, and especially if you need to remove and install the chip several times before finishing your build you won't have to solder and de-solder multiple times. You just unplug, and pull it out. Then when you wanna put it back, you just pop it on the pin header and plug D0 back in. No soldering ever necessary in that respect. However, there is still a D0 solder pad for when you need or want it. There are no power incompatibilities with 1.6 motherboards. You just rebuild the LPC, hook up D0 to the chip and you're good. The chip will not remain powered by the 5V standby pin when the console is off. The Nova has the entire pinout currently proposed by Team Resurgent. The Mini has about 80%, but has most of the features that anybody could ever want, once those things have fully developed. I have been hesitant to make an announcement for a while now because of concerns about the pinout changing or whatever else may happen. But I really didn't want to keep it to myself for any longer. I am going to go into production soon and am making sure I do everything I can to make it ready to go. I have been working on my mods non-stop for several months now (There is more than just the chips) and have done nothing else with my free time. I've worked VERY hard to try to make these things look polished and professional (Will be ENIG treated) as well as having a robust design and several small considerations that should help rule out bugs or malfunctions. I am going to do a run of the Nova and Mini, small at first and if they end up being popular, I will continue to invest in them over and over until I gain a full head of steam! Let me know if you have questions about features or how things work. The front panel PCB has a Bootsel button, Status LED and USB port for firmware updating the chip from outside the console. The status LED can have its color chosen in PrometheOS and indicates status from the outside of the console, not stuck on the chip. I'm happy with that feature. I would like to credit !!!thexkey for giving me the original template of the schematic with symbols. He asked, "Can you make a modchip with this?" I said, "I have no friggin' idea... but I'll try!" I had never heard of kiCAD or anything before then and this is my first hardware development project. I have fallen in love with hardware design and I am never going to stop! I would like to thank both him and Harcroft for sitting with me for a week or two at night and helping me understand the basics and everything I would need to know in order to get a basic modxo chip to function. It has definitely come a long way since then, as you can see here. Special thanks go out to Team Resurgent and Shalx. This project would not be possible without their work and I am so incredibly, infinitely grateful for what their work has enabled me to accomplish. I cannot thank them enough. Seriously. The status LED up front is a bit bright in these photos, but i have already dimmed it to an appropriate level since these were taken. It is no longer blinding. This can be seen in the last video, which also shows that the status LED is able to have the idle color changed in PrometheOS. I have a Discord server where people can hop in and see what's going on with the project. Feel free to stop by and get in contact. https://discord.gg/kFRKK77dEk

The following content was taken from the Xbox scene discord. Courtesy of Haguero. Its only been 20+ Years but did you know you could flash the xyclops on 1.6 consoles? If not you do now thanks to our good friend @Prehistoricman you can load Cerbios onto your 1.6 & no modchip or softmod is required. More info will be released soon but until then enjoy this video. The scene still delivering after 20+ years 20250502_022211_1.mp4 My 2 cents... This is big news for 1.6 consoles, no more will you need to softmod or modchip your 1.6 to get Cerbios running. No more LPC rebuilds This is akin to TSOP flashing an earlier revision console. Imo a modchip with PrometheOS installed is still the best way to hack an xbox, simply becasue of the extra features it brings but either way @Prehistoricman has smashed it outta the park with this discovery. Great work yet again mate

PCB files and BIOS patcher can be found on github: https://github.com/Prehistoricman/Xbox256MB/tree/master Upgraded Xblast OS can be found on bitbucket: README and Downloads The new Xblast OS comes with a RAMTESTER variant that lets you test the stock set of 4 chips. This can be useful even for a typical 128MB mod when things go wrong and the Xbox won't boot normal Xblast. MachoNacho already did a tutorial on installing this upgrade: https://www.youtube.com/watch?v=R2hvSL30Rlg So here's a brief tutorial for installation. Tutorial Be aware this is an advanced mod and while it does grant quadruple the memory, there is a performance disadvantage. The memory clock speed must be reduced to make this memory stable (this is handled in my BIOS patcher). Tools required: Hot air station (recommended for removing stock chips) Precision soldering station Microscope suitable for soldering Flux Solder Solder wick IPA Multimeter Hardmodded Xbox Spare Xbox to be able to reflash your modchip if necessary Steps: Flash the Xblast OS 0.63 RAMTESTER 256Mbit BIOS to your modchip If your modchip has only one bank, you can still access the normal Xblast menus by pressing eject to power on the Xbox. If your modchip runs an OS BIOS (like PrometheOS, Xenium or Xblast), patch it and flash it first Remove the stock memory chips. Use hot air to desolder it - I like to place tinfoil on the board to protect the other components and plastic from the heat. Or just cut the pins if you don't care about the stock memory chips. Solder in the new memory modules Start with bank 1 in the stock memory layout. See this diagram Precisely align the module on the motherboard Solder 1 pin in a corner to anchor the module Make sure you get the orientation right. There is an arrow in the corner of the module that should align with a dot on the motherboard. That's pin 1. Solder the opposite pin Check the orientation again! I got this wrong twice :((( Solder the rest of the pins on the module Power on the Xbox to test it with the BIOS If you got it right, the LED code will indicate that bank 2 has failed. See README for LED codes. If the LED code shows bank 1 failed, there may be a short circuit or open circuit. Check your soldering. If the Xbox powers off very quickly and doesn't reboot, you have a short circuit. Check your soldering. If the Xbox reboots 3x and FRAGs, there may be a short circuit or open circuit. Check your soldering. Repeat for banks 2, 3, 4 in order. Try booting Xblast using the eject button, or any other 256MB compatible BIOS. Install the rest of the banks, using the memory test in Xblast OS's Tools menu to check if they are working. Flash a 256MB compatible BIOS X2 and X3 BIOSes are known to work and have the full 256MB usable Cerbios support is not good yet, but they are working on it. EvoX will boot, but needs additional patches to be able to use the extra memory. Do nothing with the additional memory Interposer assembly One way to do this upgrade is to buy the loose memory chips and interposer PCBs and assemble them. You need to be confident with BGA soldering. The memory chip is HY5DU573222F-28 which you can find on Alibaba and maybe other places too. The -28 is the speed bin and I don't recommend going any slower such as -33. The interposer PCB designs are on Github and I've included gerbers in the release suitable for ordering from PCBWay.

I'll expand the digiex post with more info from the readme early next week. Skeleton Key's menu is a modified PrometheOS Tools menu and it features tools like XCAT launcher, The Insignia Setup Assistant, Testlaunch's Controller Test, Memcheck, Rocky5's softmod installer, and the upcoming Xbox Disk Over Network by Eaton of FatXplorer fame. I asked and was given permission to use all the currently developed applications. Many of the developers from those applications either helped with advice or provided size reduced versions of the apps to fit on an 8MB Xbox memory unit. Help from EqUiNoX, Crunchbite, and xbox7887 was absolutely essential to make it possible at all. An updated version of xbox7887's low cost USB adapter board with Skeleton Key branding will be posted next week as a branch on Github. I will be handing out some of these USB drives and adapters preloaded at Midwest Gaming Classic this weekend!

Recently received my final batch of prototype boards for the SATA adaptor. I've hand assembled 10 units of which I'll be sending out to a handful of testers. If all goes well which I expect it should, I'll create a new thread for this device. This SATA adaptor should complement the Dual Fan and Dual HDD installs nicely...

Update: I've managed to transplant a A02 cyclops into a motherboard that had a B01 and managed to flash Cerbios on no issues. Booted up to XBMC4Gamers

New toolkit released by @Harcroft! collab with lots of great peeps! https://digiex.net/threads/skeleton-key-payload-for-original-xbox.16877/

Incase anyone missed it, this firmware can be used on the Pico 2, Pico W, and Pico 2 W now, it also has a webapp for configuring deadzone and button mapping settings. I just released a new update today: https://github.com/wiredopposite/OGX-Mini/releases/tag/v1.0.0-alpha3 I tested it recently with an Xbox Series controller, which has around 6-6.5ms of average button latency, the OGX-Mini on the newest firmware tested at about 7.5 ms so it's around 1-1.5ms average. I haven't tested the wireless latency enough to say on that yet, I'll probably make some graphs at some point. As for the Duchess controller, I'll eventually add support, I just need to buy one.

Okay guys. The website is up, and I am ready to take orders. The chips come with everything you see pictured. Two cables, front panel PCB, pin header, D0 dupont (Socket) wire, and they come preflashed with the most recent versions of ModXO and PrometheOS. The github is live as well, for ModXO firmware releases specific to the board, which require some tweaking. Thank you to @shalx and to Team Resurgent. As well as !!!thexkey for helping me with the pinout diagrams and helping me understand the basics of web devving. http://www.bsxmods.net https://github.com/Bowlsnapper/BSX BSX Mods Discord: https://discord.gg/kFRKK77dEk

Cerbios v2.4.2 Beta did release. Download here: https://www.xbox-scene.info/forums/topic/445-cerbios-download-thread/

Anyone having problems with this I have made a quick how to video .thanks

I have been rebuilding a few of my Xbox HDD's recently and have built myself a little starter pack for use with FatXplorer. I thought I would link it here just in case anyone else finds it useful. Cerbios HARDMOD New HDD setup files updated.7z Cerbios HARDMOD New HDD setup files updated (GDRIVE) Includes a folder for C, E and F, that just need to be pointed to when formatting a HDD in FatXplorer or extracted and manually copied to an already formatted HDD. C contains a Cerbios.ini (set to HDD and DVD with no other changes from stock), the Cerbios BootAnims folder, a full MS Dash with Dashloader as evoxdash.xbe. E contains the XBMC4Gamers install, an Apps folder, A recovery/backup dashboard and the necessary TDATA and UDATA folders. F has an Apps folder and an empty Games folder. Dashloader is setup as below- Default dash is E:/XBMC4Gamers/default.xbe Recovery Dash is E:/Dashboard/default.xbe (UnleashX) Button shortcuts (Hold at power up)- Start = Boots recovery dash Back = Boots MS Dashboard Other buttons can be setup using Dashloader Customiser in E:/Apps. Apps provided in E:/Apps Dashloader Customiser DVD2Xbox Unleash X Evolution X Controller Tester Enigmah Videomode Switcher XBMC Apps provided in F:/Apps Xbox Artwork Installer 3.2 (If you have internet connection on your Xbox you can delete this and use the Online version available in XBMC4Gamers - Settings - Downloader) After copying across to a HDD you can edit the Cerbios.ini to your specific needs. If anyone has any suggestions of anything useful that they think should also be included please let me know and I can add it. Updated 20/03/25 to include the latest pre built XBMC4Gamers from Rocky5 PS I know this isn't an Installation Disc but it didn't seem to fit in any other category

Hi All, just wanted to share that XycloModGUI Initial Public Alpha (Ver 0.50) is now available! This is an extension of Prehistoricman's fantastic work with the initial Xyclomod breakthrough & Python tool release and is the result of some great collaboration together. XycloModGUI is a Windows-based GUI tool that aims to greatly simplify the process of "Xyclomodding" of 1.6/1.6B Consoles, with several enhancements. It does not require Python/Pyserial or other dependencies that some people have been struggling with. Further Details & Alpha Ver Download: https://www.ogxlabs.com/xyclomodgui NOTE: B01 Xyclops chips are not yet programmable. In addition to the public alpha, there also is also a developer version that has been specifically created to help the community B01 reverse engineering effort. It has functions that could cause issues if misused, but if you are technically inclined and want to support the effort, please reach out. We plan to set-up a discord channel to help share ideas & co-ordinate progress.

I'll document the serial protocol and internal registers in the repo soonish: https://github.com/Prehistoricman/Xbox_SMC/tree/master/Xyclops But the Xyclops class in xyclops_flasher.py contains a lot of the useful commands already, so if you're crafty with python you can already use that.

Thought I'd have a crack at the old legend yet again with a completely different build. This is the work of Khoa Hoang, so major props to him. @maximus64 OpenX3. This uses the original CPLD of the Xecuter 3, the Lattice LC4128V, along with the usual same Xecuter flash chips and passives etc. Currently, I've hacked this onto a redux pcb purely because its what I had on hand and didn't want to hack up the other second duff X3 purple I have after fixing the first one shown in the tutorial I made for that, as I didn't know if this would work. This actually may be an even easier fix for broken Xecuter 3 chips in due course, but I'll get to to that some time in the future, as that just complicates things here. So it's on this PCB due to a couple of trace mods only, so ignore the redux pcb, I'll get around to doing a new PCB in due course. I'm still finessing it but it's running sweet as of now, bit of meddling to do regarding that backup chip as usual. It does boot whatever is flashed on it, but being a pain over ID. Still can't get the ID of that Xecuter 'Backup' chip. If anyone can help with that it would be appreciated. It's not AM29F002BB (redux) nor AM29F002NB (n/c pin 9) either. It will read and program, but it's not the correct ID. It responds 0x 7F 7F, which means it's several steps in according to jtag standards as far as I can tell. May need Spi. Anyway, not much else to say, but it's another working Xecuter 3 chip and on the original CPLD. Config live and all that jazz all there and bank switching etc. Mentions... Maximus64 - Openx3 Psycho_Chewbacca (aka Benny T) - legend in his own right. Ryzee119 (code) Ernegien (Xbox7887) - did the x3 IO registers. Team Donkey - OpenX3 Schematic/pcb etc. ^Props to them lot and anyone else involved. Will have a look at doing the skins thing at some point if I sort the backup chip. https://github.com/Ernegien/x3cl-skins I could have done this a while ago I guess before redux, but getting more used to the Lattice software.

Here's the .jed ! Xecuter 3 jed Good luck.

Boards are live... Project is now fully open sourced. It's stated on the GitHub... but the released board (1.1) ... I do not recommend building that board as 1.5H is on the horizon (Thanks to Harcroft for his time editing and finding same quality parts at a lower cost). His edits lowered the build cost by atleast 50% and probably closer to 70%. I HIGHLY recommend waiting for this revision. Shouldn't be too much longer. Boards are ordered and will only need to be tested (they were ordered assembled)

I have currently 6 new kits freshly available. Best quality I can achieve, perfectly soldered & massive attention to detail. Spent weeks upon weeks making them. They all come with switches and cables for use, same as the original Xecuter 3 kit. All factory crimped cables. Purples have the white switch and purple power/eject pcb/cable. Reds have the black switch and red power/eject pcb/cable. All have been fully tested, including LCD use. Specific purple box & packing sourced for protection and meets UK large letter size for 24/48hr tracked service at cost. Current price as per Royal Mail website for LL. Choose either 24/48hr tracked to be added. Price is £60 / kit (same as original X3 in 2007 £60/€60/£75). Available; Purples = 4 kits Reds = 2 kits Purples: 3 kits. (1 sold) Reds: 1 kit. (1 kit reserved) Update 15/11 Purples: 2 kits remaining. Red: 1 kit remaining. Update 19/11 ONE RED KIT LEFT!! GET IT WHILE YOU CAN Paypal G&S (fees to you) or F&F.

@nikeymikey @MadMartigan @HDShadow Guys, I couldn't thank you more. Your tipps did the trick and I have ultra-crisp and brilliant graphics now. Switched on NTSC, Enabled 480 and 720, recalibrated screen - and even the font issue resolved itself. I googled my ass off and didn't find this solution. Thank you SO much for the friendly welcome, your patience and your expertise. I'm happy!

As you may know Cerbios 2.4.2 finally added the dual HDD mode to its working features, I have been wanting to test it out for a while now but didn't have all the needed pieces until recently so, over the last weekend I went ahead and got myself setup with a dual HDD system. Currently I have 2x500gb SATA drives installed as they were what I had lying around. They are setup as follows. HDD0 (original) C, E and F partitions. HDD1 (secondary) Just one big E partition. SATA Adapters are prototypes from @NeMesiS (They look great and work absolutely perfectly, UDMA6 all day long!!) The extra HDD cradle is also a Nemesis design and fits like a glove. HDD0 is powered by the original molex connector and HDD1 is powered by the DVD power cable, Nemesis' design allows you to do this and it is PERFECT for a dual HDD setup...... IDE cable is the generic yellow 80 wire that you can get from Ali, eBay etc. HDD0 has a pretty standard setup for C, E and F and HDD1 has a Games folder with a selection of Xbox games inside. Software wise, the main dash is LithiumX as this is the only dash that supports dual hdd right now. I have dashloader setup so I can access both Unleash and XBMC-Emustation directly from boot when needed. As of now neither UnleashX or Emustation support the second HDD. I boot into PromOS for FTP access to both HDD's LithiumX doesn't seem to have an FTP server. Everything on HDD0 boots as runs exactly as it would on a standard modded console, XBMC-Emustation runs as it should and all teh included emus work perfectly. Running Xbox games via LithiumX works great and so far I have not noticed any differences/issues at all with the ones that I have tried. Anyway, here's a couple of pics of the setup and a quick video showing the SATA adapters being accessed by the system (pretty flashing LEDS lol) Self built Modxo chip, using @ModzvilleUSA's board design. The chip runs PrometheOS 1.4 Console is a 1.1, yes I know it could probably use a recap Top view with everything installed, HD caddy from @NeMesiS on the left looks like it could be stock. Console up and running. The two blue lights on the SATA adapters show hdd activity. Gratuitoius shot of the closed up shell with the HDD activity light showing through the top (just) Shitty little video of the HDD activity lights in action. LithiumX is on HDD0 (original) while the game list is on HDD1 (secondary). The left light really goes into action when loading the game list for the dash. I will make a better video soon and try to show the dash in action as well. Fantastic work by the entire Cerbios team to make this a reality. Just need the popular dashboards to catch up with support for it now. XBMC based dashes are being worked on afaik. Once support is added to Gamers I'm going to build a huge storage system. On that note I have a question. Does anyone know if the 16Tb support for HDD in Cerbios is a total figure when split across 2 HDD's or can I go for 2x16Tb for a total of 32Tb??

So delaying making the ogx360i’s in favor of a project I’m working on. Integrating an xbox 360 RF power board so I can have a fully internal wireless controller option still FAR from a final product… but research and development is progressing well! I am confident enough that I can do it that I’m sharing progress

Hello! I recently finished my build of Xbox Slim case. Main goals were to be able to print it on a 220x220 mm print bed and use as many original components as possible. Only things that are needed to assemble this case is a new fan and M3 screws. It is modular and prints in multiple parts. It is available here to download: https://www.printables.com/model/952485-original-xbox-slim I have included STEP file, so adjust, change or modify as needed! I'm yet to test it with a fan, since I'm waiting for it to be delivered. If the fan turns out to be too small, I'll just make a new back piece for a 50 mm fan.

Here I have another very small batch of four complete kits of the Xecuter 3. Meticulously assembled, hand soldered pin by pin on every chip for the best I can achieve. Made over months. An enormous effort goes into making these available to this standard. These even have the correct sized thumbwheel for the LCD, complete with all professionally made cables and switches, also 3M adhesive backs (not tape) made to size. All have been fully tested including with standard HD44780 20x4 LCD output. Pin header protrusions on reverse have been smoothed so nothing sticks into your thumb etc and for overall aesthetic finish. There are 3 red kits and 1 purple kit. The purple kit comes with the white switch & purple power eject board. All are £65 each plus post. Packed as per pictures and are ready to ship. Paypal either F&F or fees to you, either way. See previous sale thread for ref if desired. Thanks. More pictures link.

New Xblast OS 0.64 available: https://bitbucket.org/prehistoricman/lpcmod_os/downloads/ Fixed the 256MB test freezing when less than 256MB is detected (sorry!)

They know the price of everything and the value of nothing... Then they buy a chinese aladdin and end up on here asking us after they've botched it up. Rinse & repeat.

Pretty sure nobody posted it here already, but I designed this DVD SSD caddy thing a bit ago and wanted to add it to this thread. There's a decently detailed instruction manual in the project files on Printables

I think by now, people know that Bowlsnapper is obsessed with activity indicators, as well as LEDs in general and this mod is one of my favorites so far! The X-Array finally makes it easy to install an array of activity LEDs in your console! Previously, this needed to be done rather manually and laboriously. This makes it as simple as soldering 6 wires and mounting a couple PCBs. That and plugging in a few JST connectors. This gives you activity indication for your HDD (SATA drives will work too), LAN and DVD drive, as well as indicating when a disc is present in the drive. I have done my best to ensure that installation is simple and easy, ensuring that all the solder points are close-by to each other and making the wires easier to organize. There are a couple unused LEDs on the front PCB, but the purpose of these will become apparent soon, once another mod of mine is released that makes use of the full front panel. I included the indicators on the actual PCB in an effort to help verify that your soldering is good and you can continue with your install. Also...it's kinda' cool. Please forgive me if there are random cat hairs in any photos. That sh*t gets everywhere and it would take me hours to make sure that they're never seen. X-Array Store Link Install Instructions

Hi All.. I have setup a torrent of the complete file download section from the long gone www.eurasia.nu. It contains not only Xbox but pretty much all consoles from around that time There is 93 X 1 gig zip files and the total is around 91 gigabyte, You will need to be patient as my upload speed is not that crash, I live is a 1st world country with 3rd rate internet. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. Xbox and more tricks and hints.torrent

A fellow forum member recently decided they would stop hosting their repo of Xbox apps/homebrew software, I was given the opprtunity to clone the repo and will now host it myself. The link is below. Original Xbox Repo Although this is a fairly large collection of OG Xbox software past and present it may not be fully complete/upto date. I am unaware exactly when the last time @RetroEmulationNation updated it. So, if any of you have any other apps/software etc that you notice are missin from the repo them please forward them to me via pm and I will get them added. Credit will be given to anyone who contributies anything. I will host on my onedrive for the foreseeable future and eventually will push the whole lot over to archive.org. Thanks @RetroEmulationNation for all your work in putting this together. It is very much appreciated.

New project IMG_0979.mov

PCBs have finally arrived , I will start working on them this weekend.

Hello everyone, I am creating this post to make every one aware that there is now public info about a 256MB ram mod that was created by @Prehistoricman. Tito has released a video about it here.

Andr0 released the X-RTC for Team Resurgent a while back and the mod has official support in PrometheOS. I thought I would add my cosmetic touch and unique board layout characteristics to this mod, as well as making it easy to install by plugging into the MB I2C connector on the BSX Nova and Mini. I added a CR2032 battery slot which should last several years. In fact, if the console is kept plugged in for more time than it isn't, the battery will decompose before it actually runs out of power, since it is only tapped when the motherboard standby power is disconnected, and the DS3231 runs on tens of microamps. The 5V LED illuminates when 1.6 standby power is connected properly and the 3.3V indicates when the VREG is outputting 3.3V to the RTC IC, or when the 1.0 - 1.4 standby power is being tapped directly. I added a test LED to make sure that the battery is good, and the "Run" LED which blinks to indicate when PrometheOS has successfully programmed the mod and you know that you are good to go and put your case back together. You can also see it through the side vents and see your Xbox's heartbeat. I have made efforts to make this mod as simple to use and to install as possible, with the I2C input plugging straight into the BSX modchip, as you see here. However, this is not strictly necessary. You can run wires to SDA/SCL and standby power solder points on the motherboard and use the mod as long as you have a chip that supports PrometheOS/Cerbios. In fact, you can use a TSOP Cerbios flash, update the ini as outlined on the github and then program using the version of PrometheOS I also have hosted on there. Just solder the I2C to the PIC controller up top. There is an I2C out, for people wishing to use HDMI mods that use the SMBus in general for programming/configuration. I am already at work to make the install process for the BSX-RTC even easier, as I feel that the installation could be made so with a little more effort. Thank you to Andr0 for creating the mod in the first place. His simple, elegant solution sparked the project! Thank you to Team Resurgent and Team Cerbios for supporting the mod. A BIG thank you to Jade for helping me learn how to pack the custom ModXO and PrometheOS code I have for my chip to work properly and as desired, allowing me to offer a singular flash file to image to my chip instead of two.

I ported my Dreamcast game Matterrun, written in 2016-2017, to the original Xbox. If anyone is interested in trying it out, you can grab it at http://atari.vg-network.com/fuseki No CD image, FTP only. Here's a video of the game running on the Dreamcast while it was still in development, just a few days from release. It plays the same on the Xbox:

All of the work listed here has been with @dtomcat's support and approval. In fact I specifically waited for permission before I even started looking at finalizing the board for him. I have to do final assembly and testing on each board, but all parts are now on hand. This is a ground up re-creation of the original design. All traces laid down fresh, most components have been replaced with lower cost, equal or higher quality alternatives. All data lines were redone to be much closer to length matched. Bill of Material (BOM) list for Digikey, LCSC and JLC are all complete. PCBA files for these boards with JLC PCB will be included with the new source files, as well as 3 part LCSC BOM for the 3 through hole components if a user does low cost PCBA. Reset and Boot Sel buttons require 30% more force than the originals but equally or more easily accessible. This is to help protect from accidental button presses. Resistor and capacitor numbering has been standardized, redundant capacitors have been removed. Oscillator has been changed to a lower cost, non programmable, easier footprint to fill model. Green LED resistor lowered to make the brightness between the LEDs more even, and a more visually appealing emerald green LED was chosen to replace the original yellow/green LED. Serial TTL/UART port added (unpopulated) for dumping the user password from locked Original Xbox stock Seagate HDDs. Documentation added on both sides of the PCB to make the pogo pin adapter intuitive to use. Two holes added for M3 screws if a user wants to use a 3d printed shield or case. The existing silkscreen has been redone from scratch as well to improve readability. All software functionality is identical to original PicoPromSD. Here are some pics of the first assembled board. It's not fully clean but it'l give you an idea of what the new model looks like front and back. I'll be assembling the rest in the next week, as well as producing pogo pin adapters and seagate HDD adapter cables. EDIT: The inclusion of a reddish WRITE EEPROM button was intentional. I wanted to it to sort of warn the end user not to press it unless they meant to, even with the existing software protections.

I had a big order of BSX Nova and Mini chips made, since I honestly don't have time to be making these by hand. I have been testing with the latest version of PrometheOS (1.5.0) and making sure things work as expected. I am working on the website and would like to make sure that people have a place to order them from by the end of the weekend. Displays work as expected and now do not have to be bodged between the Motherboard I2C and 5V VCC/GND sources. I am reasonably confident now that anything else that needs to be added can be largely done in firmware. Check with ya in a day or two. Edit: SPI2PAR courtesy of @lopenator

@DoctorPixel whether you knew they were older versions or not, you still advanced the design by adding the socket. Even if it does hang over the side a bit . My post was also to show that as a mod I was aware of the thread and hopefully that would stop the thread from degenerating into a shit slinging show. you handled your response perfectly tho tbf and both you and @TKsCustomSuperModz showed how adults handle things properly.

I've been thinking a bit and I wanted to express some thoughts. I believe I have created a nice chip and created a nice starting point for the project. I have tried very hard to create something that is quality and that people would be proud of saying that they have in their systems. However, this project would not be possible without the efforts of Shalx and Team Resurgent. I may have been able to read some datasheets and connect some blue lines in KiCAD (Albeit for the first time in my life), but I think it would be a bit ridiculous for me to act like this has been all me. I was developing a hardware embodiment of the ModXO firmware, and trying to create the best physical representation of what this firmware is capable of and what it has the potential to. Code is a powerful tool and I am confident that Team Resurgent has the skill and drive to pull it off. I should thank Shalx specifically for hanging with me and answering my questions when he has the time to do it. So here's hoping that project BSX succeeds. It can only do so if ModXO enables it to. Thank you to the community and everybody who contributes to both Team Resurgent and ModXO, both directly and indirectly. https://buymeacoffee.com/shalx?l=de?t=true https://ko-fi.com/teamresurgent

Here are some screenshots of the Half-Life 2 version that will be present in The Orange Box compilation Running at HD Resolution (Real 720p) made by Silverrock along with a High Resolution Texture Pack (512x512 HD/1024x1024 FHD and 2048x2048 2K) Ported Directly from the PC 2004 Version! The FPS as Jay mentioned in the other topic is my focus after this, but this will take more work, as I see that the only solution will be to optimize the game's original maps, since there are many leftover files with no functions which is exactly what ends up causing the GPU stuttering, a 60fps patch would be welcome, but it wouldn't help much until this is improved. This same map optimization will be done in Episodes, Portal is not necessary because it does not demand as much from the GPU since the maps are much more closed compared to Half-Life. .bmp Functions that I have functional and that will be implemented on the UI in the for quick User modifications: Aspects: 4:3/16:9/21:9 Resolution: 480p/720p (Only 128mb >) (it works with 64mb, but it is not recommended) Upscaling: 480p to 720p (External Output to 64mb consoles) Texture Quality: Low/High CPU Clock: 733Mhz/1Ghz/1,4Ghz Rendering: Hardware/Software FOV Flashlight: 70°/90° FOV Jeep: 90°/120° Exiting the game to return to the UI and from there to the Xbox Dash.

Didn't know where to put the thread, just wanted to show off my little achievement. I haven't had much to do with PCB building yet, but I've just received my very first little project today and had to test it directly. And it works, i'm happy. Nothing special, just the 4 needed resistors, a diode for protection and a power led. All pins from the rp2040 zero are connected and placed outside for future changes or projects. Also all pads described (except one (modxo status led) i forgot) Also some traces for 3V3, 5V and the Xbox SMbus, maybe it's useful later.

What started as a small project to create Kiosk Demo synopsis, led to updating almost everything I could find for the Xbox. Standalone Arcades and Halo Map Packs from Dominater01's Archive, Emulators from Emuxtras, Homebrew from wherever I could find, Project Deluge prototypes, and CoinOPS/OpenBOR/SORR. The only things I didn't update were Apps and Dominater01's Modded games. I'm burnt out for now and need a break, and my 365 trial expired, so no more Excel. I sent out pm's to every developer I could find asking for info on every item, some didn't respond, so if something is wrong, you'll have to update it manually in Notepad++. I'm sure I didn't get everything right, as a lot of info just couldn't be found easily, most notably Single-player or Multiplayer, 720p support, Online Play, etc. If a game didn't specify these, I put Single-player, and left the other features empty. I ran Rocky's scripts to extract every xbe's info, TitleID, SourceName, FolderName, and input what it gave. If it looks funny, that's just how it is, specifically japanese titles. If the xbe didn't have a SourceName, I used the title of the game. I started out creating Override_TitleID's for the homebrew, but that's just too monotonous. Ain't nobody got time for that, I've got bronchitis. If I ever go back and work on these, I may get to them then. But if you have trouble with something in the artwork installer, the TitleID is probably 00000000, or a match to another game. Just grab one of my Overrides from a homebrew game, change it from Override_TitleID.bin to Override_TitleID.txt. Create an 8 digit ID for your game, save, change back to bin, and install. I'd like to thank @Cian Cunningham for his awesome Spreadsheet, without his formulas I wouldn't have got nearly this far, and Rocky's artwork scripts, which saved a lot of time. Big thanks to @Rocky5 and @nikeymikey for explaining how to use Rocky's scripts in Photoshop also. I also used a few thumbnails for Root Sources, by @RoofTop , Emulators and Homebrew, resizing them a bit so they load faster. The Arcade, CoinOPS, and OpenBOR Root Source thumbnails are from Destronger's emuxtras repo, as is the xMugen set. I just added the Xbox banners and resized to load faster. The art that I somewhat created is Metroid Ninja, Premium Castlevania, the random Deluge protos and its source thumbnail, and the Halo map pack thumbnail. I used Rocky's generic controller resource sets for most everything, so they looked tidy. If something has a screenshot or a video preview, it's from that actual game, not a placeholder. I've also installed generic Halo CE/2 artwork for the map packs, and BOR art for those as well. Everything has some kind of art included, so it's not just an empty looking xbe file. This mostly came from Rockys artwork installer, I just installed it to save you time mindlessly copy/pasting. Be sure to keep an eye out for nikeymikeys XBMC4Gamers resource thread on here for better art that I can provide. There should be original Release Dates for everything in my packs, as the spreadsheet has them completed, but I don't see a way to enable them, unfortunately. I spent a lot of time finding that info. Hopefully, this can rejuvenate interest in the scene, once people start reading the descriptions and realizing there are some cool games out there in the homebrew scene. You don't need any of these games installed to use the resource sets, just ftp the folders, takes about 30 minutes, then press White, Add Source, scan the folders in, and have a look around. You may find something that sounds interesting, and go download it to try it out, who knows. I tried to put the most important info of the descriptions at the top of each game as it scrolls, and the changelogs, updates, etc, are at the bottom. If something doesn't have a description, it didn't include a readme.txt file, or I couldn't find info related to it online. I spent time on every single game, without over doing it, so it should be easy to read. Don't forget to Press Y in XBMC4Gamers' dash, to view the enhanced synopsis info, and press DPAD Right, to tab over to the Screenshots and Video Preview, if available. Rocky says not a lot of people even know this exists, hopefully I can get others to give it a chance. Just make sure to not have a music playlist going in the background, or it will run out of RAM on a stock Xbox. LT/RT super scrolls also, very handy. I don't know what the View Type is called in dash, but in XBMC4Gamers v2.1.001, it's at the very top, 3rd one right. There are only 2 that are darkly shaded, this one scrolls horizontally. I think it's the best experience, myself. Here's the link. Have Fun! And keep an eye on nikey's thread for future artwork. -Nok

Update: now able to detect when a controller connects and able to properly shutdown controller when power to Xbox is turned off IMG_9916.mov

The new 1.4.0 version of prometheos is released, lots of changes has been made. Download here: https://www.xbox-scene.info/forums/topic/450-prometheos-download-thread/

Oh that's right Cerbios has dual HDD support now. How's that been going? I should update that kit to the "Dual HDD Kit"...
