Thanks to Clownacy and Neo for pointing me in the right direction getting the PC-relative instructions working. asm, but maintains the ROM:xxxxxxxx line headers from IDA for convenience (I used it to help brute-force a first working build). The _ida.txt file includes all the fixes in. ![]() idb is attached in unaltered form for reference. If you make any edits, you'll need to fix the checksum yourself (I think GENS should be able to do it for you too), but then I suspect as it stands right now any significant edits will just break the ROM.Īndlabs' original. To build it, just drop asm68k in the folder and hit build.bat. There's still work to be done on this before I'd be convinced it was safe to hack.
