Regarding U8: MX "E062674-MG" "MX23L4005-24C1" "RTC-RVL A" "2S08802" (RTC, TSOP28 18x8mm)

U8 is actually a Macronix Mask-ROM. Some data shows that it contains GameCube Fonts when accessed in GameCube mode. This could also contain boot/initialization code. The data sheet is here: http://www.datasheetcatalog.com/datasheets_pdf/M/X/2/3/MX23L4000.shtml -- PaceMaker

• Hi PaceMaker - I think that almost certainly can't be correct, the chip specified by that datasheet has the wrong nmber of pins. I have heard there's a part on the gamecube that is similar (is both an RTC and an encrypted firmware rom) - I haven't looked into it personally yet though. --Sgstair 22:23, 5 September 2007 (MDT)

• Sorry for the confusion. I just counted the pins and realize you are correct. BTW, here is a link to the GC docs that mention a little something about the RTC/ROM chip in the GC. http://www.gc-linux.org/docs/yagcd.html
• My new wild guess is that it's a serial Mask Rom. -- PaceMaker

• Yes, that's reasonable. I have it from good sources that the GC chip was a RTC/serial rom --Sgstair 17:19, 7 September 2007 (MDT)

• Do you know of anyone who's been able to dump that ROM? It seems like it shouldn't be too hard to find the right 3/4 pins. Do you know if the GC chip was protected from dumping? -- PaceMaker
