TBA's 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 TBA's 8gb uSD card for the 2600-UNO! It has HUNDREDS of files

Note: All known retail releases, including SuperCharger files, are known to work. Most files, including Pitfall II, runs fine on 99% of systems. The firmware has been adjusted (we are on version 13) to maker sure of maximum compatibility. However, someone always seems to find a system it does not like, so there you go. That being said, we have not had a report of problems since the v13 release in October. Please check the manual for specific details. However, no guarantee is made as to whether a particular ROM/file will work or not.
Recent home-brew releases that require DPC+ commands will not work yet.
Additionally, some non-standard 2600 Audio/Visual modifications may prevent the UNO-2600 from working. This does NOT mean your UNO-2600 is defective. Returns because the UNO-2600 does not work with your A/V modification will result in a re-stocking fee.
