Pokemon Ruby GBA Game Boy Advance game cartridge Nintendo’s mega-popular monster-battling RPG is back with Pokemon Ruby and Pokemon Sapphire for the Game Boy Advance. These new Pokemon quests take players on a journey through Hoenn, where they can train, battle, trade and earn badges with a new set of Pokemon. Ruby and Sapphire offer over 100 new Pokemon, and completely overhauled graphics, thanks to the power of the Game Boy Advance. A new two-on-two battle system raises the level of strategy and excitement, as a single player can simultaneously battle two Pokemon. Multiplayer options have also been expanded as two players can battle against each other with two Pokemon each, as well as a new four-player battle mode.
