Soeren, If memory serves me correctly, amiga music is in the format of modules. It has no midi support (without a midi adapter). If you don't know about modules, they are somewhat like midi files, but contain the instrument sound files within them (or in a separate file) and play those. Like a sort of sampling machine. I know that Monkey Island 1 used the TFMX module format, but I have no idea about the other games. There are about a bazillion different module formats for the amiga, and some games even wrote their own custom format.
I'm not so sure it would be a simple matter of changing the music code to read the amiga music files.
