Currently, the Disassemblies use at least three differents assemblers: - SNASM68k - ASM68K - The macro assembler AS SNASM68k, according to what I've read, was an assembler used to build official games. However, there seems to have been many complaints against it. ASM68K is only used for the Sonic 1 disassembly as of now. I've tried to search for some information on Google about this one, but I couldn't find anything relevant. Does someone have documentation on this assembler? I'd like to know what I can do with it, as I'm using it for my Sonic 1 "hack". AS is great, but there seems to be a few problems with the Sonic 1 disassembly (after replacing incbin's with binclude's and splitting dc's with more than 20 arguments - I could use some help if I'd ever like to do things ASM68K can't do). Also, it seems to be a bit slow with Sonic 2, compared to ASM68K with Sonic 1. tl;dr: what's the "best" assembler for Megadrive/Genesis games?
