Robopon 2: Ring Version: After becoming the Legend1 of Porombo Island in the original game, Cody sets off to a new land, and a new tournament. Things take a turn for the worse when a violent storm destroys Cody's boat, and sends him adrift at sea. He awakens inside a shack in the land of Majiko-but all is not well. He discovers that the nearby lands are being terrorized by the Maskman and his cronies. In order to put things right, Cody must travel back 20 years into the past, and then return to the present. Similar circumstances await in each new land that Cody visits. It soon becomes clear that his troubles are more than coincidental, and he unravels Majiko's many mysteries while challenging contestants in the tournament. Cody's rival, Bisco, follows him from Porombo Island and interferes throughout the quest. But is Bisco causing all these problems, or is someone else behind them? gameboy-advancecheat-codesroboponringversion
