Nervegas has released a new version of his Nes Emulator for the iPhone:

NES.app uses the popular InfoNES emulation core to mimic the 6502 processor in a Nintendo Entertainment System, allowing you to play ROM dumps of games designed for the NES console. ROM dumps are files containing the dumped instruction code from a physical cartridge. In many cases, you are legally entitled to posess a ROM dump of any game that you presently own. ROM images for NES are widely available online, or with the appropriate hardware, you can dump them yourself directly from the cartridge.

NES.app started as a fork based on the same original code as iPhoneNES, but has been completely rewritten to run very fast, and with many additional features such as sound, game genie, saved games, and full screen support.

1.8.0 [nervegas] Fixed white noise channel frequencies
Fixed PCM DMA
[jordan] Added PAL support, use filename (E) unless marked in header
(Many are not marked in the header)
