A while ago I put together a small project to flash the Atari Jaguar Skunkboard flash cart from a Raspberry Pi (More details here). The Skunkboard can only hold 1 or 2 games at a time so it was nice to not have to keep removing it and plugging it into my PC to flash it.
Since I built that, I have kept thinking about making it more compact and building everything into a single cartridge. Well, I finally got around to it, and here is the end result:
The cartridge has a DC power jack on the top which is powered from a USB cable. This provides the power to the Raspberry Pi as I didn’t want to risk drawing too much current from the Jaguar itself. The rotary encoder on the side of the unit is used to scroll through the game list and select which game you want and what bank to flash the game to.
I think it turned out pretty well. If you wish to build your own then subscribe to my mailing list from the homepage as I will be uploading the build guide and required files in the new year.
