2021 Edit: FFmpeg has added support for LEGO Racers' tun and pcm files as of version 4.4. I advise everyone to use that instead of this program as this program isn't 100% correct. Thanks to mumboking for bringing this to my attention.     Original post: Although I had already posted my ima2tun program >here, I've decided that a separate topic might be more easy to find. This zip file contains my ima2tun program tunconverter, SoX, and some handy-dandy batch file
