The Wide-Boy (also referred to as Wide Boy or WideBoy) is a series of peripherals for the Famicom, Super Famicom, and Nintendo 64 that allowed developers to test handheld games on a television screen, akin to a Super Game Boy or Game Boy Player. Manufactured by Intelligent Systems, the Wide-Boy devices were never released to the general market, and were only sold to developers, press, or retailers for displays.


The Famicom version of the Wide Boy unit is a large circuit board containing all of the essential components that make up the Game Boy hardware[1]. On the top is a black cover to protect the board, with the exception of the space where a Game Boy Game Pak is inserted. On the bottom of the board is a top-loading connector that inserts into the cartridge slot of a Famicom unit. A Game Boy unit is wired to connect to the Wide-Boy via an external connector to serve as a controller.

When the system is turned on, the game will by default be displayed with a background similar in design to a Game Boy unit. By pressing A and B on the Famicom's controller, the player can cycle through different color palettes.[2]

Super Famicom[edit]

The Wide-Boy64 was a Nintendo 64 cartridge wired to a handheld that served as a controller, as most of the handheld's actual circuitry is inside the actual system. Two versions of the Wide-Boy64 were produced: The Wide-Boy64 CGB, used for Game Boy and Game Boy Color games, and the newer Wide-Boy64 AGB, which could also play Game Boy Advance games. The cartridge is larger than a normal Nintendo 64 cartridge, and has a space for the respective cartridge to be inserted on the top.[3][4]

The Wide-Boy64 CGB surrounds the game with a display resembling a Game Boy Color's screen, while the Wide-Boy64 AGB displays the game in a box with the Game Boy Advance logo underneath. When using a Nintendo 64 Controller with the Wide-Boy64, the player use the analog stick to zoom in on the game image. The player can also reset the game by pressing R and Z simultaneously.[5]
