BUILDING

0. You will need to install the arm-apple-darwin toolchain. See:

    http://iphone.fiveforty.net/wiki/index.php/Toolchain_Project 

    You will also need to apply the patches in toolchain-includes-patch.txt Run the patch in your toolchain's include directory. For example:

           cd /usr/local/arm-apple-darwin/include
           patch -p0 < toolchain-includs-patch.txt

1. Compile using 'make'. This will create a new NES.app package in ./build.

    Upload entire NES.app directory into /Applications on the iPhone and reboot the iPhone. It should automatically detect the application and add it to the springboard. 

2. Place your ROM files in /var/root/Media/ROMs/NES

NOTE ON SOUND Sound 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"

NOTE ON MULTITOUCH The multitouch reports mouseDown and mouseDragged events separately, and so you can run while holding 'B', for example, but the iPhone appears to get pushed to the limits when you are holding a direction and dragging on another. It fails to report the necessary mouseUp events to distinguish which button(s) let up, and so they must all be reset. As a result:

Versions >= 0.20

    If you are doing something complex, such as running with B held down, then jump with A, you will also need to slide your thumb back off the directional pad (to zero, or to the other size) to stop running. 

Versions < 0.20

    Whenever you are holding a direction + button, releasing the button will cause the direction to stop moving as well. I am working on finding a way to poll the screen to re-evaluate all the buttons, but until then, this is the only caveat you'll have to live with. 

NOTE ON DEBUG

Compiling with -DDEBUG (see Makefile) will enable debugging to be sent to /tmp/NES.debug. At the moment, this is only recording touchscreen activity.
