Hello all, I've managed to figure out the symbol/address/line file format that ASM68K.EXE dumps out, in order to add source level debugging and symbol searching to an emulator wrapper tool I've been helping out with. Sample source (C#) here: https://github.com/BigEvilCorporation/ASM68KSymbolDump There's also a SNASM68K.EXE version I made a while ago, too (C++): https://github.com/BigEvilCorporation/SN68KCOFFDUMP Matt
