Emulator Issues #11467
GameCube IPL BIOS data is wrong
According to Dolphin, NTSC-U BIOS is different than NTSC-J, so when you put an "NTSC-J" BIOS in /GC/USA/ it'll complain that it's a JAP IPL
According to redump/MAME, however, NTSC-U and NTSC-J are the same BIOS, and the NTSC-U BIOS hash that's been used has garbage in the last 0x8000 bytes
After bringing it up on IRC,
<Extrems> Yeah, US and Japan are the same. <Extrems> The only hardware difference between them is a resistor's location.
There's an older issue at https://bugs.dolphin-emu.org/issues/10113 but doesn't have enough information to solve it.
Will probably have to fix up the wiki too (found this while googling for info) https://wiki.dolphin-emu.org/index.php?title=Template:Problems/GC_Font
