This is a package with modified music - namely tracks from Chrono Trigger SNES as I recently tried out the game and it had decent music.
I was just trying this out as I always wanted to experiment making a PoP game with custom music (modifying the DOS version was tricky with PR, works only with PoP 1.3 and then only MIDI songs).
No modified levels or graphics, the only change is the music {but with the songs adding abt 18mb in size).
SDLPoP with custom music
If aspiring modders for SDLPoP wishing to add music to their mods can try out what I did.
Simply google 'ogg converter' or 'convert to ogg'. I found a decent online converter aconvert.com that can convert and trim songs.
With this, you may even choose to use your favourite rock/rap/pop song (or even RickRoll) as "intro_theme.ogg" and watch it play at your starting screen
