The Game Gear version of the Game Genie had a more complicated design than those for other systems. When inserted into the cartridge slot, another slot would pop-up to insert the Game Gear cartridge. It also had a compartment which contained a book of codes. The codes were printed on sticky labels to put on the back of the Game Gear cartridge. When entering codes, the player could easily see what to type in rather than looking through the book.
In the code input menu for the Game Gear Game Genie, a player typing the word "DEAD" will cause the screen to move up and down, possibly as an Easter egg.
Again, some games do not work with this version of the Game Genie (see "legal issues" below).
