iPhone “jailbreak artist” ZodTTD released a video showing psx4iphone, a PlayStation emulator, running on a non-jailbroken iPhone 3GS and it looks great (see video below).
I now have psx4iphone running very speedy on the 3GS. It’s at the point where Final Fantasy 7 is fullspeed at very least without sound. The build is rough around the edges, as you can’t switch games without restarting the emulator, and only memory card saves are currently working, no save states just yet. Both these issues are being worked on.
Wanna test this on your own iPhone 3GS? Hurry up! ZodTTD is giving a chance to 40 lucky peeps. Check out his blog for more details.
