Some hacks that I see go out of their way to actually change the SEGA sound that plays before the title screen, to something else entirely. I'm curious as to how it's done, and I haven't seen really any guides on this when editing music and sounds. And I'm guessing that's because editing the SEGA sound isn't as easy? Of course, I could be missing a very obvious guide like an idiot, but that doesn't seem to be the case? I do get a kick out of it when it's done though, and I do want to give it a shot for whenever I eventually make a proper Sonic 1 hack.
