The emulators don't have this sort of freeze/stop behaviour, they actually start playing the music earlier and that's why it's done from the beginning without delay like it should. The delayed music playback problem, according to what I noticed on the game behaviour on emulators and on the console, is because on console the game does some kind of a freeze/stop mechanic (it seems it tries to load something) and then when the music starts sounding it's already a couple of seconds late. Especially the Snake Pit level one is a nuisance because you can't pause at all on that level or else you'll have to restart the game.

So if you don't have a SD2SNES then that's probably why you didn't notice it and I don't know how easy is to fix those. The point is, BSNES and SNES9X don't reproduce those problems, but SD2SNES actually does. It doesn't matter if you use cheats or not, if you have the checksum well or not, or whatever. Those are problems are specific of the MSU-1 hack. You don't have to look that issue at all.īut unfortunately the music playback problem starting a couple of seconds late and the issue with pausing/unpausing freezing the game on the Snake Pit levels are still present. I fixed the checksum on the MSU-1 hack and that problem got fixed, so one problem less. After some investigation, I noticed what was causing the graphic problem in the Dark Tower level and Dark Queen boss was a checksum problem conclicting with the infinite lives cheat, given that the MSU-1 hack doesn't fix the checksum when patching and that's why I had that problem on the MSU-1 hack with infinite lives and its bad checksum but not on the normal ROM with the same cheat applied which had the checksum right.

The graphic problem in the Dark Tower level and the Dark Queen boss was also appearing to me in BSNES and SNES9X, unlike the other problem withe Snake Level pause and of course the music playback problem which only happen on the console and not on emulators. Ok, after numerous playthroughs of the game through SD2SNES, BSNES and SNES9X, I have the problem issue fully documented.
