"Baffatari" is the codename for the Baffa Atari 2600 board that allows you to run atari games on a computer with a 6502 CPU. It is currently part of the setup that allows the Baffa-2 to run programs like an Apple-1.

Baffa-2 is an educational and personal project with the aim of understanding how computers work through 80's 8-bit commercial machine designs. It has a modular concept with boards that can be combined to develop your own design and configuration.

Baffa-6502 is a subproject of Baffa-2 to create a new series of boards around the 6502 CPU architecture. This allows a new group of  retro computers to explore in my project.

The first "setup" is an Apple -1 that runs Atari 2600 games (like CP/M that runs Colecovision) and is still in development. For now, I was able to test the new Atari 2600 card for the Baffa-6502 (Codename  "Baffatari" 2600)

  • Loading Games from Cartridge or SDCard

    For now, I can load games only by listing (hex code) via terminal, but I've designed two ways to load games on my apple-1 replica/baffatari.

    If you have an Unocart or old cartridges, you can use the backplane's peripheral port to attach a cartridge expansion. This allows you to run games directly from the cartridge.

    But, there is the option to load the games via SDCARD... The SDCard board is based on P-LAB's "Apple-1 microSD storage card".

    Both boards will be available soon... Can't wait to post videos showing them working :)
