SSF is the best emu I've used. Plays my games and ROMS well.
If Sega put the original Sega Rally on XBLA for 1600 MSP, I would hit it up in a flash.
I'd also pay that for pixel perfect ports of Daytona(not CE), Dragon Force, Burning Rangers and Sonic Jam.
Add Sega Touring Car if they get rid of the contextual steering.
Well I'm not quite sure about the actual game, but I know they re-released it for the PS2 in Japan (as part of the Sega Ages collection) a few years ago.
If you click on the little box in the upper right corner (looks like an animated gif), then you can check out the promo video.
I've been thinking about picking it up for awhile eventhough I already have Dragon Force (both the US and JP versions) for the Saturn.
@op: I love my Saturn (Saturn > PS1 for me) and have ever since I got my first one in 1995 (for Christmas), I think. It's too bad my US modded Saturn doesn't work anymore (drive doesn't spin up at all), but I still have 2 JP Saturns.(one with the extra MPEG adapter card, which makes Lunar: SSS MPEG version look great! http://www.youtube.com/watch?v=aDOE8GUlIAA&fmt=18 )
It's great being in Japan, because I can pick up so many Saturn games. I have so many Saturn games that I've picked up for pretty cheap, I only have a partial listing in my profile. The only exceptions being rare games, which are of course expensive. I still want to pick up Radiant Silvergun, but it usually costs in the $150-$170 range, whenever I see it.
