  == Accessories == I'd like to point out that the Tilt-Sensor is NOT an accessory.  It is built in to certain GBA Game Paks, and used only in those games.  I think it's just Warioware Twisted and Yoshi Topsy-Turvy.  I don't believe that a technology built into certian games should be counted as an accessory.  That's like saying that the clock is and accessory for the Game Boy since it was included in the Pokemon Gold and Silver games.
