The author remixed this model.
I erased the Gameboy logo so that a custom logo can be added such as the pictures above. I teach my elementary students how to code their own video game using arcade.makecode.com and have them take home a “physical” copy of their game by printing their title screen as the label on these cartridges. A QR code linked to their game is printed on the back of the cartridge.
I also enlarged the opening slot and scaled it down so that the original size can fit in a Gameboy.
