Game Mage (January, 1994)

The GameMage was a Taiwanese peripheral that worked like a Game Genie, with the difference being that a whole slew of codes were already built into it, which saved you the time of typing in the codes you wanted each time you went to play and negated the need for a code book like the Genie used. You could also type in your own codes if the ones you wanted weren't present, and it would take Game Genie codes as well. The NTSC version of the device featured a port meant to hold a backup RAM cart to save user-entered cheats, but the backup cart never appeared. In PAL territories, this was replaced with a slot allowing NTSC games to be plugged in and played, bypassing the region lock while also allowing code input.
