I personally like the OGG file format better for Mugen. As far as the music goes, I thought that the original music was a little to electronic and cheesy sounding for Prehistoric. So I found some music from the game Civilization that sounded similar, but better. I placed both in the pack so you could choose for yourself. Thanks for the comments. I hope to make all of the KoF 94 and 95 stages with those cool intros.
