Game Pak is the brand name for ROM cartridges designed by Nintendo for some of their earlier video game systems. The "Game Pak" moniker was officially used only in North America, Europe, and Oceania. In Japan, as well as other Asian territories and Latin America, these cartridges were officially called .

Even if this was bypassed by using a Game Boy Pocket, Game Boy Light, or Super Game Boy, and Super Game Boy 2, the game would not run, and an image on the screen would inform the
