NES.app lets you play Nintendo games on your iPhone. It is a fully functional, feature-rich Nintendo emulator.

NES.app uses an emulator core we call NESCore, which we’ve forked from pNESx and InfoNES and re-engineered as a highly-portable and high-performance Nintendo emulator core.

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 sound, multitouch support, full-screen, landscape mode, game genie codes, saved games and much more. It now contains zero code from the original iPhoneNES project.

Changes:

[nervegas] Jacked up volume
[nervegas] Compiled with debug on; no debug seems to mess up colors
