GameShark Pro for Game Boy Color and Game Boy Pocket

This is a GameShark Pro peripheral device manufactured by InterAct Accessories, specifically designed for use with the Nintendo Game Boy Color and Game Boy Pocket handheld systems. Released in the late 1990s, the device is constructed from a dark charcoal or black textured plastic featuring a distinctive 'sparkle' or metallic flake finish across the shell. The design is elongated compared to a standard cartridge, with a bulky top section that includes a pass-through port for inserting a game cartridge. A physical trainer/snapshot button is located on the top left edge. The front face features a black adhesive label with 'GameShark Pro' in a green stylized font, and 'InterAct' with its purple 'i' logo. The label explicitly states compatibility 'For use with the Game Boy Color and Game Boy Pocket'. There are visible signs of use including light surface scuffing on the plastic casing and minor edge wear on the label. The plastic edges show some dust accumulation in the crevices, but no structural cracks or significant damage are apparent. This device functioned as a code injector, allowing players to access cheats, infinite lives, and hidden game content by intercepting data between the game cartridge and the console hardware.
