Rings of Power is a isometric role-playing game released on the Sega Genesis in 1991. The game at the time was much like PC role-playing games. Young sorcerer Buc is on a quest to find the eleven rings, restore the Rod of a Creation, and destroy the evil Void once and for all.
As the Genesis is being turned on, hold down the buttons A, B, C, and start, along with the d-pad in the diagonal/lower right position until the Naughty Dog logo comes up. If done correctly, in replace of the Naughty Dog, a topless women will come up.
