Welcome to my Motorola 68000 programming reference. It consists of 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.

Note: The instructions addi and subi cannot repoint a dynamic pointer. For the following instructions, addq and adda are valid, but addi is invalid. Use adda instead. The instructions addq and adda work equivalently in these examples when given the same arguments, but adda allows greater arguments than addq allows. The corresponding sub instructions work parallel to the given add instructions.
