I played the dull and grainy black and white one for the game boy when I was a kid. I was shocked years later to learn there was a colorized GBA version and that it was based on a SNES game, which was super cool to me.
GREAT soundtrack. Just happy and uplifting to listen to, despite the 32-bit limitations. Makes me wish I had been born a bit sooner to enjoy KK in all its glory.
