Emulation hasn't quite stepped up to NAOMI yet, nor CPS3. I haven't followed emulation as much recently as I did a few years ago, though. Last time I checked the emu community had a semi functioning Model 3 emulator, but no roms. I think it ran Sega Rally 2 at like 5 fps and you couldn't play it, so SFIII would be hard to do. All of these games are out on consoles anyway, and the Dreamcast versions of CVS and CVS2 are more than adequate ports. I used to have an MvC2 arcade stand-up I bought at auction for $150 with a bum monitor (huge green bias). All I had to do is rewire the CP and tweak the monitor and it played just fine. I ended up selling the guts for close to $400 on ebay. W00T.
