After receiving your modded Nintendo with the Hi-DEF NES board you can pull up a special menu. To pull up this menu, make sure you have a game running, then press and hold SELECT then LEFT ARROW on your controller. Please see below what each menu option does. It is recommended that you write down the original default settings just in case. If you have any questions concerning this guide, let us know.
