Welcome to my Motorola 68000 programming reference. It consists a table containing useful examples of the 68k instructions, and it can be a very nice tool for everyone who is hacking MegaDrive / Genesis games in a hex editor. For your help and confort, the parameters in the ASM commands have been coloured along with their respective places in the 16-bit instruction codes.
