Hi guys (and galls)
I haven't had the time to test this out yet, but I spotted something on the devpage of SofiyaCat (dev of PSPtube and poc of porting DS emulator and allot of other stuff)
it apears as if she is porting Yabause ( http://yabause.org/ ) to the psp. Yabause is a Sega Saturn emulator.
I hope she puts some more work into this and doesn't drop the project, I've been looking forward to a sega saturn emulator :)
if anyone is willing to try, go ahead.
