Yes that's turning the chip into the xblast version so you need the 080a flash chip as Bgsmods59 says. Effectively making the jafar chip from aladdin.

Pity you are over the pond and not local to me, would have a look at for ya. But never mind just pickup a cheap battered case one that's functioning maybe and use that board. Onwards and upwards as they say. Shit happens.

Are the pads and tracks lifted at the ram? Might be saved if you can clean it up and just use it as a 64mb standard console?

That's unfortunate.

Yes you can replace the flash chip to a 020A, that should work. You can also just remove the 002 chip and flash it externally using a cheap USB socketed flasher to PC off ebay as well.

Yes, the 8164b uses a windows based flash tool though opposed to the usual DOS based ones. An 8163b is good, but requires the dos flash. You might find the older 616T tosh drives, but they are old as well.

You said it works fine with the MM cable yeah, so surely you just need to continuity test comparatively each contact and track end to end to match up the same on your flex? Any disparity will be the prob if there. Vaguely remember Ryzee hadn't shown or done a 1.6 flex on his github page, but noticed a slight difference on the 1.0 to 1.4 compared to the MM one IIRC.... not looked at it still for ages, still too busy right now.

That's the issue, if a ram chip has a problem, then it probably won't work to get to the Xenium OS as its now a hardware error. Still easier just to flash xblast on a dumb chip like an aladdin. Might be a flakey glitch and only works on certain boards/setups. Never bothered testing it myself having so many chips available. Might try it next ram upgrade and see. Did you try holding the eject button after the frag?

Boom .... was right first time... V1 is write protected. Enable flashing

Highly probable, I had to reflow several pins around the Xilinx CPLD on my duox2 to repair it. The switch was also faulty, but that's negated on his chip.

Probably needs the pads top right in your pic linking to enable flashing.... as to which ones need linking I have no idea as mine is a duox2 as well. Might find the original instructions for the DuoX on wayback machine etc.

Not something I've done myself, but might find some pertinent info here on this thread regarding your issue; Kreon 0800 drives thread.

No. 'Frags' has somewhat become a generic term, when really there are of course different boot errors that flash on the LED ring. FRAG refers to 'flashing red and green' which generally indicates the hardware is okay to a point and that the BIOS has a problem - the lack of greater than 64mb ram sequentially in this instance for the BIOS unsupported, whilst Xblast does. Other Errors can flash red/orange or red only (usually hardware) etc. It was known you could get Xenium OS to boot by doing the above while adding ram.

Cheers Dave, couldn't see it on my bookmark list.

Correct.

No. Depending on the power supply, there was a thread on here about modifying 120vac to 220/230vac input, some can be linked to accept the other voltage. Do a search for the thread regarding this mod and use at your own risk.

It's just an LG 8164b dvd drive. I have a few of them. I also have the PCB's to make the Xbox dvd fit the same so it just plugs in. The Kreon drive is a different system and you need to find a suitable dvd drive, see here > http://forum.redump.org/topic/6073/xbox-1-360-dumping-instructions/

Guess the Pi series aren't a 100% solution then if that's the case in a digital domain and probably why the Xbox HDMI went with a hardware 7511 chip to negate this then. Makes sense if the signal is waiting on another OS and processor compared to a hardware video processor chip. I notice lip-sync on films in ms which drives me up the wall so couldn't tolerate lag if it came about.

and here's the last PC dvd drive mod for the 8164 LG which will read an Xbox disc with the DVD drive still in the PC. Works in the xbox of course as well. Think it had a few minor issues with a couple of retail games (layers?) but runs sweet mostly. Done by MrPresident. https://assemblergames.org/viewtopic.php?t=59732

Like the others, I'm not here to dissuade you from your quest..... and it IS a quest. Many moons ago circa 2002 onwards as xbox-scene developed (yes it was a great site) the DVD replacements were already being done, the firmware swaps to 616 PC drives and the LG one too. Also other PC drives to play backups etc.... I was one who found the elusive 'z' point on the Sonys at the time, but anyway I digress... You will find, as the others and Prehistoric has told you, firmware is key - simple as that. Its binary, old, tedious and takes a lot of time. Yes there are very talented guys out there that can do it... https://www.vogons.org/viewtopic.php?f=46&t=67897 Also see the Gotek, same sort of thing. They will all want paying for their work & time (usually) unless they are just keen, interested and like a challenge. As far as your say Samsung Xbox drive that's gone duff, I can tell you more often than not, it's not the laser, it's the PCB. There are two versions of the board as well just for that model. I had the service manual for a near identical model and again, as previously said, the firmware source is not available, so will need reverse engineering. Tattiebogle obviously knows his shit. But look what he charges for the arcade one! See where this is going...? If you really want to run genuine discs then another angle maybe rather then trying to manipulate PCB hardware firmware (difficult) you could maybe look at running a PC dvd drive to actually recognise and spin up a retail game disc - that's where it may be best to start. The trouble with that is the drives firmware won't accept the Xbox disc... that's gonna be your first primary hurdle before anything else. People like the 'dangerous brothers' used to do this work in the past (long gone) for region free changes to drives etc and better performance on DVD burners for example. These are the types of guys you need to find. <taken voice> Good luck!

The only stream I know is the one I fish from! <====Old fart

Shouldn't really be any lag, the Xbox output is digital. Not analogue like the Amiga etc.

Yes, I have 3 Pi Zeros, and another wifi one as well. Whether the LAN could be fed in as well is another matter and kind of off-topic to this already off-topic suggestions really. But yeah, I had thought of the Zero before the HDMI xbox mods arrived, but oh well, that's what came about as it stands unless someone with Pi knowledge can take the same digital pre-encoder feed and code the Pi appropriately for it.

Those QSB and SPD boards look mint mate. So does the rest for that matter.

I'm into some of the older retro stuff than even the Xbox, like Sinclair Spectrum as that was my childhood gaming era in the eighties... I've seen a lot of other PCB's and HDMI solutions for various vintage consoles and computers back then, including the Amiga for example and they use, in my view at least, an easier approach to this HDMI issue. Mostly they use a Pi Zero, which has the HDMI already and of course the license to use it. So it's interfaced on the 2x20 riser to the retro computer, usually with a buffer daughterboard for the video input. RGB on the Amiga for instance. Even the Spectrum next uses a zero as an accelerator (not video) so its a cheap versatile bit of kit. Beyond my remit to interface the digital xbox video into the Pi zero, but seems an easier option that was overlooked to me.
