I'm not such a programmer or ripper, just can some things. Probably, I can do this rip in YM format (not AY). But there could be a problem that I may miss some music, especially if the game is long and/or hard to complete. The other problem that if the game play SFX with the music, your friend will have to listen to them also. I think I would try, but, unfortunatelly, I can't guarantee the result. Anyway, thank you for the suggestion.
