I always wanted to play it.. Almost bought a Saturn just to play it, but luckily I chose a PSX instead as the Saturn died shortly thereafter..
Not a lot of people use Saturn emulators from the looks of it.. And also, Saturn emulation still has a LONG way to go, so it could be an emulation glitch as well. There really are not a lot of settings to play with in the first place either.
I don't think we'll see real good general emulation for a while yet. Best you can do is wait it out probably,
