Can anyone name me the other types of video files found on Sega Saturn games, and whether or not they can be converted? I want to rip the Sega Satanshiro commercials and post them on Japanese Gaming, but am having a hell of a time finding them. The only thing on the discs I can find of any size are audio files. There's about 5 CPK files, but they're very small -- definitely not the commercials.
Any help is appreciated.
