TBA UNO-2600 Cartridge for Atari 2600 & Atari 7800
The UnoCart -2600 is an Atari cartridge emulator. It supports cartridges with up to 64k of ROM and 32k of RAM. First, copy BIN, ROM or A26 files to an SD card and insert it into the cartridge. It comes with a printed manual , and is in a 3D printed case with a choice of three professionally printed labels. It works on PAL & NTSC systems! It will also run on most 7800 machines (but will not run 7800 ROMs).
If you do not have files to run, consider purchasing the TBA 8gb uSD card for the 2600-UNO! It has HUNDREDS of files
