11-in-1 MultiCart
I decided to make a MultiCart system for NES using MMC1. It allows you to easily add 11 of your Mapper 0 (aka NROM) NES games to a MultiCart ROM. On powerup there will be a menu listing your 11 games. Using Up and Down you can move to the game you wish to play and then press either Start or A to load that game. Once the game is loaded if you press Reset it will just reset the selected game. To return to the Menu you should power off and on.
