Atari 2600 Unocart

This project is based on Robin Hedwards' great "multicart" solution for the Atari 2600.
Al details about this open source solution here: https://github.com/robinhedwards/UnoCart-2600/

This version is one of the most compact size available. It works out of the box. All you have to do it load some Atari 2600 ROMs into a microSD card and insert it into your Atari 2600.

A menu will list all the ROMs available. Go up or down with your joystick and press fire to select the game you want to play.

1 - Setup

Insert the microSD card into the card reader.

2 - Select the video mode (PAL, PAL60 or NTSC) best suited for you TV using the jumper. This is only impacting the menu. Try all 3 mode to see which one work best with your TV.

3 - Insert the Unocart into your Atari 2600. Make sure the words "THIS SIDE TOWARDS USER" is facing you. The microSD card is also facing you like so:

2 - Alternative Firmware

As stated above, this UnoCart is based on R. Edwards project. The latest firmware release for this project is R18 from Sept 12 2023.

There is an alternative firmware called "UCA" you can install on this hardware.
