SEGA Saturn Emulator released for the PS3!
The wonderful French PS3 users over at PS3GEN.FR have post an early version of Yabause which has been recomplied to run on your XMB GameOS via your Jailbroken PS3 console.
It is very early v0.1, so don't be complaining about it, but they are hard at work in improving it, and I will update the attachment when it improves.
I've tested it and it very laggy.. won't boot at all.. bios start then return to XMB its a french site so sorry no translation....
