I used the MT32 audio. Not only because it sounded better, but because it would overload the CPU and slow down the game making it playable on my Pentium 75.

My old PC wasn't good enough to play the game. You could almost see each frame render. However, the PC speaker music was really nice and I used to run the game just to listen to that.

I actually came here to post this. It's iconic music, bleeps and bloops!
