prefetchPatch makes bad assumption: not all GBA start at 0x80000C0 #228

khmann commented 2 years ago

While working on a personal GBA project, I noticed the function "prefetchPatch" (gbapatcher/arm9/source/main.cpp) sets the ARM7 PC=0x80000C0 when done, but several hundred of the nointro .GBAs don't actually start there. Perhaps 0x8000000 is more correct?

The 2,3,4 in 1 carts are common offenders, also here are some randoms: ./Asterix & Obelix XXL.gba: 8000000: ea013ffe b 0x8050000 ./Cars.gba: 8000000: ea000031 b 0x80000cc ./Final Fantasy IV Advance.gba: 8000000: ea00041e b 0x8001080 ./Final Fantasy V Advance.gba: 8000000: ea000407 b 0x8001024 ./Incredibles, The.gba: 8000000: ea000031 b 0x80000cc ./Mario Golf - Advance Tour.gba: 8000000: ea00010e b 0x8000440 ./Mario Tennis - Power Tour.gba: 8000000: ea00011a b 0x8000470 ./Pokemon - Ruby Version.gba: 8000000: ea000032 b 0x80000d0 ./Pokemon - Sapphire Version.gba: 8000000: ea000032 b 0x80000d0

EDIT: this is actually TWiLightMenu++ code specific to DS/DS Lite Slot2 usage, but the open issue button dropped me here... whoops.

We can't transfer the issue to TWiLight's repo as this repo is on Gericom's account instead of the DS-Homebrew org so I'd suggest closing this and making a new issue on TWiLight's repo.

Maybe we should make that more clear that only ROMs go here, though it does say that in the description ;P

Created issue in TWiLight's repo as it is not related to this project. Closing here. Thanks for all your hard work!
