Well, now the problem is with sound. I followed every step of the WAVtoPCM guide, and still there's no audio. I chose the necessary loop sample, converted with all the right data, ran the wav file through command prompt, got the pcm file, renamed it to my file "ff1234.wav" as per my video file "ff1234.msu", dropped it into the folder, booted my SD2SNES, aaaand... No sound. Should I rename it somehow, or maybe I missed something? I'm very sorry for being too dumb to comprehend all the tricky and not so clear info.
