Emulators that allow you to use custom soundtracks for games

can anyone get me a known list of which emulators support this? Im really starting to get sick of the stock music with games. especially when I practice

If this is a normal feature I don’t remember ever stumbling across it. I think the best you may be able to do is mute the music and play your own music in an mp3 player. Check an emulator like Final Burn and see if it allows you to toggle off the individual sound channels/music.

Kawaks has it, it has a winamp jukebox option
