Recently Nintendo releases Wii games have shown #002 error if you are launching from GeckoOS. Here is the fix: change following pattern in main.dol (DonkeyKong Junglebeat JP), 2C 00 00 00 40 82 02 14 3C 60 80 00 to 2C 00 00 00 48 00 02 14 3C 60 80 00 (Sorry, I fixed too many 00s. 2C 00 00 00 is right) then you can launch DonkeyKong JungleBeat JP from your GeckoOS. (Actually I tested this with GeckoOS 1.7b mod04 + cIOS based on IOS37 that supports Korean Discs) the patch above is bypassing new check routine (#002) of OSInit of Wii soft. Possibly this can patch NFS undocover as well. but I think the main excutable is not main.dol for this case. there are dol and elf file in the disc file system. Good Luck!
