Released in celebration of the 20th anniversary of the hugely influential Nintendo Entertainment System console (which first appeared in Japan as the Famicom, in 1984), the "Classic NES Series" of Game Boy Advance cartridges present accurate versions of original NES games, for play on the handheld.

Former plumbers Mario and Luigi have been sent to rescue to Princess Toadstool and restore peace to the kingdom. They must make their way over land, under ground, and through the sea, in eight worlds divided into four levels each. At the end of each world, the brothers come face to face with Bowser, the evil king of the Koopas, who must be stopped before the quest can continue. ~ All Game Guide
