I've just put the opening music back again, it was deactivated for test purposes when I was troubleshooting the CD music issue with user Eric H on X (the music that was failing to play was just Vampire Killer, the first level track, others seemed fine). There must be a way for you guys to test an ISO on real console without having to waste a blank disk or wear the reader (and thank you very much for the help, the experimental nature of the project and engine calls for a lot of trial and error until things are fine).
