This first description was taken from Amazon.com: "It is a Game Boy emulator for the Nintendo 64. A N64 game is plugged into the back of the item and a Game Boy cartridge is plugged into the top. Like the Super Game Boy, it connects to the N64's cartridge slot and requires a N64 boot cartridge plugged into its back, and allows you to play Game Boy games on it. There is also a cheating device programmed into it, called the "Golden Finger" (like the Game Genie or Game Shark). Holding the 'L' and 'R' buttons simultaneously will cause the game to freeze at that point and the GB Hunters' Menu to appear. The Game Screen can be maximized or minimized, from the Main menu, allowing the player to see the game full screen. The GB Hunters color palette can also be changed from the menu, to view the game in a variety of the 3 different colors. Most sellers of this item, on eBay and other places such as the EMS site itself, do not mention that the video game sounds while being played on the GB Hunter are not emulated. Rather, users are subjected to the theme song of the GB Hunter, which loops endlessly."
