Azu: short answer: no. Just open SONIC3K.DS2 in Goldwave as a raw pcm file (22050Hz, 8 bit, mono) to find out what's going on. The sound format (sample rate, bit depth, channels) isn't specified in that mini-header, there are only the file lengths in there, all the sound effects must be 22050Hz, 8 bit, mono, unless someone alters the exe file. I'm already working on a pcm importer/exporter by the way, it should be ready in a couple of hours, stay tuned. EDIT: also suggesting a split since I don't like to derail this music thread with discussions about sfxs.
