I'm currently replacing some of the game musics found in the "MDX" folder. I already made things like putting some MG and MG2 remixes in the normal game. But a problem appears when I try to import any music from other places.
It appears that the MGS music files are wav files using PCM Audio at 22050 Hz 8 bit stereo. I manage to convert the foreign music files to this format, and the game initially plays them, but also turning out in a constant repetition of the beginning (I mean, the melody doesn't progress as it should).
What should I do to solve this? Using a specific program? Does anyone know how these files really work?

Hey! You still don't have a Sega CD?
What are you waiting for, Nintendo to make one?
