Rayman Pirate-Community

I want the music and sound effect from the PS1 version but without having to compile DOS-BOX.

Yeah, and I want a copy of a platforming prototype of RRR

Seriously though, there are plenty of TPLS options for getting the music without rebuilding Dosbox yourself, like in the Rayman Control Panel for example. As for the SFX, I feel like that should be possible by hacking the game (not Dosbox), but I don't think anyone's done it yet.
