Atari 2600 UnoCarts

Oct 28, 2023 | Retro Gaming

A quick and fast project to make a “multicart” for the Atari 2600. The UnoCart 2600 is an open source SD card based multicart for the Atari 2600.

My build was based off UnoCart 2600 v1.03 project here on the PCBWay community projects. The project is based around the STM32F407VGT6/7 chips. Most of the parts are available on AliExpress or Mouser, the STM32 chip can be expensive to get if the stock is low. The soldering can be a bit tricky if you haven’t done hot air soldering before. 

The programming can be done with the ST-LINK V2 via the pins on the PCB, I didn’t both with the pogo pins to program it. The firmware can be found here.

After than, it was just a matter of formatting an SD card as FAT32 and copied over a folder organised 2600 game library.

The STL files for the cases can be found here, they needed to be chopped/modded for this board to fit.
