Console emulators were one of the first orders of business when the jailbreak scene took off two years ago, but they've always been plagued by stuttering framerates—especially the more ambitious ones. The iPhone 3GS fixes this, gloriously.
Jailbreak stalwart ZODTTD has ported GBA and PSX emulators to the 3GS (which isn't quite jailbroken yet), and the results are stunning, even in light of the promising benchmarks we've already seen. Most impressive? As you can see in the video above, Final Fantasy VII for the Playstation runs perfectly. For reference, it absolutely crawled on the 3G and iPod Touch, to the point that is was irritating to use, even as a novel tech demo. [ZODTTD via Nowhereelse]
