Goal of this part of the website if to list all existing handheld cartridge consoles. Not all the cartridge games.
All game variations are listed separately. Even if just the color is different.
Sometimes publishers publish a game from another publisher and only put their sticker on the box and not on the game itself. Those are only listed under the original publisher.
Some publishers publish under different names in different parts of the world. They are listed under each name separately.

In case of nice ideas for the website or game information errors or missing games, you can contact me by mail.
