If you like to play old-school video games, getting out an emulator once in a while may scratch that itch. For true retro fans, however, it’s hard to beat gaming on a dedicated console, such as the classic SNES. Assuming you can find the correct ccables, such systems are a matter of plugging in, turning on and mashing buttons! Perhaps, however, you’d like to go further and experiment with new firmware, or back up that valuable game in your collection to avoid potential damage.
If you’d like to burn new cartridges that can plug into your SNES, look no further than the M27C322 Pre-assembled Repro PCB SNES Homebrew SNES by Tindarian Michael Cardoza, AKA Ampere Sand. The process, as seen in the video below on a different iteration, involves programming an M27C322 EPROM chip with game data, and then attaching it to the PCB-cartridge via solder or headers. The device comes a programmed CIC (Checking Integrated Circuit, i.e. lockout) chip in order to allow your games to run. It also comes with pre-installed RGB LEDs with jumpers to select the color on display, and space for you to add your own LED if you so desire.
While the board by itself can’t save game states, it does have space to add SRAM and a battery to keep things alive if needed. Ampere Sand is also offering a similar M27C160 EPROM-based PCB-cart, though it doesn’t list the same saved game accommodations as its M27C322 cousin.
