Super Nintendo Cartridge Circuit Board: SA-1

This is an unpopulated circuit board you can use to make your own homebrew SNES games, or repair old games that no longer work. You will need to purchase components and solder them to the board yourself. This board uses the 27C322 UV EPROM, which can only be found used on sites like eBay and AliExpress. You can find all the information you need to assemble, configure, and program this board at my GitHub: https://github.com/MouseBiteLabs/Super-Nintendo-Cartridges/tree/main/SA-1

This cartridge design is for use with the SA-1 co-processor found on some advanced SNES games, which you will need to remove from an existing SA-1 game. The board can fit in SNES shells for games that used enhancement chips, as well as standard SNES games (with some minor cutting), and provides:

• Up to 4 MB of ROM space
• Up to 128 KB of RAM space

You can find example builds at the wiki page of the GitHub: https://github.com/MouseBiteLabs/Super-Nintendo-Cartridges/wiki/SA-1

This project is open source, so if you would like to order your own from the PCB manufacturer of your choice, the files are available in the GitHub repository. Just be sure to match the exact specifications as listed (thickness, surface finish, etc).
