How's Sega Saturn emulation?
Mednafen's semi-new Saturn core is basically the best one right now next to SSF. Mednafen's a little better now actually because you don't need to mount images to run the games, plus a couple of small glitches present in SSF's emulation don't happen in Mednafen.
Shit. None of them allow high resolutions outside Yabause with is shit.
