Did you already try tracing the code? Just set a breakpoint on the code's starting address right before the shell hits it, let it snap a few times until the shell hits, then find the crash point from there. Easy. | |||

Hmm... Not related to the issue, but what compiler are you using? The one you're using looks pretty easy to use. (Right now, I'm using a hex editor and a 65c816 reference file when programming in ASM. ) |

A modified version of SnesASM by Kenny9000, which unlike the original, doesn't add the 512-byte header and pad to 32K. (Don't suppose it's an assembler bug?) |
