NES.app is a Nintendo emulator for Apple’s iPhone. NES.app uses a modified version of 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 of iPhoneNES v0.01, but has been completely rewritten to run very fast, and with many additional features including full sound, game genie codes, saved games, battery-saved ram support, and full screen support.

Changes since v1.00 RC4:

Back to toolchain v0.20
Fixed PCM wave channel (Zelda sword, Punchout Cheering, etc)
Fixed buzzing on audio channels 1 & 2
Fixed game genie entry screen
Added “PCM Sound” preference to turn off PCM if problems
Fixed delete swipe to hilight correct table cell
Replaced reset button for mute button

NOTE: 1.0 Saved games are incompatible with previous versions !!
