  • Handmade


This is a custom printed circuit board I designed that you can use to make your own homebrew SNES games with, or repair old games that no longer work. This Basic board is great for making smaller games at affordable prices, or for using original parts from another damaged SNES game you might have that still has good parts on it.

Detailed information on how to construct the finished board, its full capabilities, and a parts list can be found at my website.
Resistors should be rated for 1/16W or higher. Capacitors should be rated at 16V or higher.

This board has three options for memory chips (not included): the 27C801 for making 1MB (or 8Mbit) games, the 27C160 for making 2MB (or 16Mbit) games, as well as support for the original SNES ROM pinout for either using the original ROM chip from another board or for using 29F032 TSOP adapters for making up to 4MB (or 32Mbit) games. Note that if you are using the 27C801, the ROM file MUST be swapbinned. This board also supports up to a full 1024Kbit of RAM with the 1008 SRAM series, but also supports the 6264 and 62256 SRAM series as well. If you want to use 27C322 for 4MB games, make ExHiROM games, or make multicarts, please see the Advanced version of this board here:

Please, check out my website listed above for extremely detailed instructions on how to construct a game of your own, and if you have any questions, contact me!

Looking over the boards I received they are all uniform and very clean. Nick was even awesome enough to combine my shipping for multiple orders. Will definitely buy again in the future.

Highest quality SNES boards I've ever worked with! Second time ordering, experience was just as good as the first. Also, very helpful (and patient) in that tight moment where I may or may not botch something.

These cartridge boards have well, thought out designs, and are of a very good quality. Definitely check out the links on the sale pages for install help and and a wealth of information regarding creating your own custom retro carts. Mousebite was quick to ship the order, and it arrived well-packed for transit. I would love to see some Famicom pcbs make it into the store :)
