Nintendo NES Cartridge Circuit Board: MMC3

This is an unpopulated circuit board you can use to make your own homebrew NES games, or repair old games that no longer work. This cartridge is mostly made from brand new off the shelf components, except the MMC3 mapper. You will need to remove an MMC3 chip from an original NES or Famicom game.

This circuit board can be used to make most MMC3 NES cartridges. You can find all the information you need to assemble, configure, and program this board at my website: https://wp.me/p8J8CO-US

I plan to open source this project soon. Stay tuned for more information.
