CoolNDS runs best on modern quad core devices! If running on an older device, enable frame skip and disable sound for max performance gains

CoolNDS appears to have good compatibility, sound is a bit glitchy, and game play a little laggy. However most games are fully playable.
Unfortunately CoolNDS has one major downfall. Unless you have a menu button on your phone or an external controller you can not access the options/system setting.
CoolNDS has minimal ads that do not interfere with game play.
CoolNDS is based onnds4droid.

CoolNDS was tested on an HTC One M8. Keep in mind that older or less powerful devices will, more than likely, have more lag and more degraded sound.
