The Arcade Gamer, also known as the Poga and as the Master System Portátil in Brazil, is a Sega Master System and Sega Game Gear console on a chip manufactured by AtGames. The Arcade Gamer has been distributed by several companies under different names and colour schemes, in both 20 and 30 game variants. All share the same plastic shell - a controller (also seen with the Mega Drive Twin Pads) with an extra C button, despite no Master System or Game Gear games ever making use of it. The same shell was used for the Mega Drive-based Arcade Gamer Classic.
