THIS is an SD card for the Atari Gamestation Pro Console. I am not selling the Console. Don't assume I'm selling you a console

If your system is running version 1.2 (see menu options/about on your system), you can use the 1.2 SD
if your system is running version 1.3 , you can use the 1.3 SD card, which will allow more systems, and be more organized.
If you are unsure and cannot check, I recommend the 1.2 SD
