hey everyone, i replaced the cap in my 1.6 xbox and also finished the modchip (atleast i hope i did) and before i hooked up the dvd drive and hdd i tried to test it but all it does is come on and then go off and it does it twice and then on the last time it comes on and flashes red and green over and over, the mod chip has a orange light on and i am also attaching some pictures of my wire job let me know if i did something incorrectly EDIT: i looked for a different diagram and found i had done two wires wrong and now it is booting perfectly!

D0 does not have to be connected on a 1.6 console. D0 is an output from the Aladdin chip. It should not be tied to ground. It grounds the D0 point for 1.0-1.4/5 Xboxes. Not required to be connected to D0 on the motherboard for a 1.6 since it always boots from an LPC connected device be it the Xyclops chip or the modchip. Cutting LFRAME prevents the Xyclops BIOS from loading.

Use a meter and the pinout diagrams and you can check what each of the wires should go to. Ignore the colors of the wires, I trust a meter more than a color code.

There's a small writeup about the MuppetX modchip at xbox-hq.com: https://www.xbox-hq.com/html/article1692.html Wayback Machine captures of various installation picture pages from xbox-scene.com: v1.0-1.1 v1.2-1.5 v1.6/1.6b It has a 1MB flash chip on it - SST49LF080A but I don't see where you select the bank to boot from if it actually supports more than 1 bank. Update: I see now the switch on it is the bank select switch, not to enable/disable the modchip, but to select one of the two 512KB banks. From what I've read, flashing the chip with Evoxdash use a 1MB dot bin file with the BIOSes combined into one file with the bank select switch set to bank 1. copy /b 512KBBIOS1.bin+512KBBIOS2.bin my1MBbios.bin If the BIOS 1 and 2 are actually only 256KB then create the two 512KB BIOS1 and BIOS2 files: copy /b 256KBBIOS1.bin+256KBBIOS1.bin 512KBBIOS1.bin copy /b 256KBBIOS2.bin+256KBBIOS2.bin 512KBBIOS2.bin Or much easier using the Xecuter2 BIOS Manager (X2BM) and load the first 2 banks with the same 256KBBIOS1.bin file and the last 2 with the second 256KBBIOS2.bin file. Select all 4 banks and save the new 1MB dot bin file.

Already turned on the converter which has upscaled and remove lots of ghosting and now is 1080p, quite happy probably the best image this console can get .

Sorry for the long delay in responding, missed your reply posted. Yes, you can use an RPi and PiPROM software to read/write the Xbox's configuration EEPROM. Read/Write an Xbox EEPROM with a Raspberry Pi

I've seen a download link to the Lamborghini (unleased) game. Not sure if it's the full version or other pre-release demo version.

any pics of progress? my commentary on the paint job is: "i found you some cover art, please see below" .... I could probably ship you a dickie betts action figure if you promise to glue it to the top.
