I've added the NSF files to the Snailiad soundtrack page. Originally, I only uploaded MP3s, because the NSF for Moon Snail didn't export correctly. I figured out the problem, though (stray values in the instrument column), and updated the soundtrack page with the NSFs :-)

By the way, make sure you check out xdanond's game, RPG Shooter: Starwish! I wrote music for that game :-)
