The Sega Master System II Power base was a cosmetic and to some extent, hardware update, to the original Master System. The cartridges were inserted under the black plastic interface that says "Sega Master System II". This slid back to expose the cartridge port. The round grey button is the PAUSE button and the small black oval switch is the "ON/OFF" switch. All the cartridge games functioned properly on the SMS II, but because of the lack of a card port, the Sega Card games and the 3D Sega Scope Glasses were not usable on the SMS II. The built in game for the SMS II was Alex Kidd in Miracle World. All you need to do to play it is turn on the SMS II without a game in.
