ok, so i got all excited and wrote some changes to softchip to do the error 001 hack to main.dol in memory. it didn't work, but maybe this will still help people who had the error 001 with modchips, but then you'll have to change softchip to use regular ios 55 (or ios36 if that works). im pretty sure the patch works correctly, but if someone patched main.dol, updated the iso, and burned it, and it worked, then we'll know there is a way for this specific patch to work. i only implemented the error 001 fix from the generic wii patcher.
maybe requiem can use this to more quickly make a fix, assuming someone finds the source of the error in the dol file. I have included main.dol for the pal release of need for speed: undercover, but I don't have the ntsc release, so someone else will have to test it with that (don't think it's out yet tho). if any1 does have it or gets it, maybe you could post main.dol for it as well. i'm starting to wonder if there's a possibility this is a bad dump (wiierd, release #995 according to gbatemp), don't think so since some have gotten it working though. there's been two other releases of what appears to be the same game (#1005 and #1014), maybe someone could also test those to see if the same error occurs or if the error 001 fix or ios patch fixes the problem. i think the other releases just have different languages though.
there is another file on the disc that might also need to be patched: NfsMWEuropeEnDuRelease.dol, not sure how this is different from main.dol, since i can't extract it right now (not enough hd space lol).

from those who have gotten it working on a modchip: does it work with ios 55? (im guessing yes) does it work with ios36? (some have said yes)
has anyone actually gotten it working on the backup launcher with NO modchip?
edit: nicksasa: the error text is also in main.dol, i wonder if main.dol is a copy of NfsMWEuropeEnDuRelease.dol, which is just the dol version of NfsMWEuropeEnDuRelease.elf... they could be files left over from development of the game. if they are the same or basically the same,but different in some ways, it might be interesting to replace main.dol with the content of NfsMWEuropeEnDuRelease.dol. not sure if that will work tho.
