NES.app v1.10 - Nes Emulator for iPhone

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.

1.1.0 [nervegas] Removed unnecessary mutex locking for layer write
Draw black box around emulator screen to prevent see-thru
Improved sound quality slightly by precaching more audio
Added status bar icons (for suspend)
Added more debugging
Removed unnecessary screenUpdateLock
Corrected Bubble Bobble color palette
Demand direct installation
Corrected intermittent crashing issues
