Console produced for each of the two video coding standards (Pal and Ntsc), the Atari 7800 has cartridges dedicated to these two video modes. But unlike the Atari 2600 games, which offer very good compatibility between these two formats (apart from the colors), the Atari 7800 Ntsc games do not always work correctly on a 7800 Pal console, if at all! Here is the list of each game, with its operation (or not), followed by a brief technical explanation. The latter is detailed after the table.

Note : If you have one of the twelve games not tested in Ntsc, as well as a Pal console, please let me know the results so that I can complete this table.

Glitches en bas (Bottom glitches): Ntsc games on a pal console produce glitches at the bottom of the screen. Depending on the frame of the screen used, these may be hidden by the bottom of the screen. As this is a generalized phenomenon in all games, it is not mentioned in the table.

Glitches: More annoying, glitches produce defects anywhere on the screen. It's still playable, but it's disturbing.

Tester le Gun (Testing the Gun): Two games are played, not with the joystick, but with the Light gun. If they both seem to work very well, the guns have not been verified to respond well (remember that the optical guns only work on a CRT).

nv : (non vérifié) (unverified): information found on the internet, but which I have not personally verified (for lack of the cartridge).

Écran d'intro (Intro screen): Some non-working games only display the intro screen.

Flickering: This effect produces a strong flicker. On an old CRT television, the effect may be less disturbing depending on the persistence of the screen.

Presser Select au démarrage (Press Select at startup): Two titles are known to be able to be launched by pressing Select when the console is turned on. However, these two sports games each have an event that crashes the game.

Ultraspeed: Some games have music playing very quickly, and others speed up gameplay. At the limit of the unplayable, these can be considered as a new challenge!

Of the 44 games tested, 26 are playable, for a ratio of around 60%.
