If my memory is correct, I've read somewhere that Croc was released for the PC
before the PS1 ... so it makes sense why the first version of the game would have less musical variety...
It's actually funny how I started the search for the song. As a kid, the third Game Boy Color game to come into my posession was Croc. Even at that age, I thought the game's music was really cool, and because I have such a memory for music in general, those 8-bit tunes never left my head. It wasn't until I was older that I learned from a friend that Croc originated in the world of 3D platforming on the PC. I didn't look into it very much until I decided to see if anyone had posted the 8-bit tunes from the Game Boy Color game on YouTube. Instead of finding the Game Boy music, I ran into tracks from the PC and PS1 versions. Turns out the Game Boy themes actually originated on CD! It was amazing to be hearing fully arranged versions after all that time...
So yeah, thanks anyway! :>)
I don't own any version other than GBC...
*edit*
BTW, I mixed two similar tracks together for a neat blend between 8-bit sounds and PC red book audio; check it out with the YouTube link here:
