I cant find source there, just windows exe files which are totally unusable
for me. I don't too much about this IMF format, however choosing DRO has a
major advantage: it's about the simpliest format possible, it's simply
register number and data pairs, the heart of the player code is something
like this (well, there is a codemap table to translate, but it's just two
additional opcodes, so let's forget about it - with the delay too):

loop:
... load a byte from DRO stream into register A
STA YM_SEL_REG
... load a byte from DRO stream into register A
STA YM_DATA_REG
JMP loop

I can't easily imagine that you can find simplier format to play back than
this :)
