Super Nintendo Cartridge Circuit Board - Advanced



Star Seller. This seller consistently earned 5-star reviews, shipped on time, and replied quickly to any messages they received.

  • 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 Advanced board supports the popular 27C322 EPROM and is great for easily making a single game up to 4MB (or 32Mbit) without having to use surface mount TSOP parts. It also supports up to 8MB (or 64Mbit) games split over two 27C322s, and can even be used for making multi-carts! The SRAM size has been expanded to a full Megabit (or, 512Kbit for multicarts) with the 1008 series of SRAM (still accepts the 62256 and 6264 series SRAM).

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.

A video detailing the build process can be found here: https://www.youtube.com/watch?v=2Z5QZY2BEU4&t=34s&ab_channel=TheBucketMouse

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!

Built my first SNES repro following the easy instructions. Everything but the eprom was provided. Worked on the first try. Highly recommended. Website is an awesome resource of free information too!

Very nicely done, the boards I got are chock-full of options, I can't wait to investigate and start running my own code on the SNES.

Already bought some full cartridges from this store, and their quality is just amazing. I desoldered EPROMs too many times and they are still as good as new. Perfectly fitting in any cart shell and perfectly working in my SNES. You can find nothing better than this!

If anyone had told me as a child that making my own SNES and NES carts as a hobby would one day be possible, I would have dropped all other aspirations and patiently waited in my room for 2021 to arrive. Anyway. All of Nick's products are great and essential in enabling this intoxicating hobby. Here's a shot of my white whale of an ExHirom repro which was as easy to get working as soldering those connections and option pads.
