iPhone NES emulator
A new version of iPhone NES emulator is now available. The iPhone Nintendo Entertainment System emulator allows iPhone owners to play classic 8-bit NES games on Apple iPhone, and this new version adds audio support and more.
iPhone NES emulator comes with some very popular NES games, such as Mario Bros, Megaman 2, and the original Metroid.
Installation instructions: ROMs need to be placed in /var/root/Media/ROMs/NES.
NOTE ON iPhone NES Emulator Sound; it is required that you disable mediaserverd, and only works through the headphones. A couple of easy aliases can be added to your .profile to disable or re-enable mediaserverd if you are using MobileShell:
alias nosound=”launchctl unload /System/Library/LaunchDaemons/coreaudiod.plist”
alias sound=”launchctl load /System/Library/LaunchDaemons/coreaudiod.plist”

Of course it’s suggested for everyone that still has the old version to upgrade to iPhone NES v0.20.1, which you can download below.
