Well, this looks like what everyone has been waiting for, a SNES emulator that takes advantage of the PSP's GPU. I've already tested this out on a few slow titles, and the improvement is definitely noticeable. You can download it here.
Also, if you're impressed with this program and want to help out the developers, you can drop some change through Paypal at the authors' site.
Enjoy the new emu and discuss about it in this thread! :)
