Ever find yourself in the middle of a Game Boy game and your hand cramps up? Save that sore wrist for something else because now you can hack the Game Boy Advance to add Rapid Fire for the B button. [William] has developed a way to do this by creating a simple circuit that generates a square wave on the B button when it is pressed. To do this hack all that was needed was a short shopping list of:

•A Couple NAND Gate ICs
•2n2222 NPN Transistor
•0.1uF ceramic capacitor
•A Switch
•1M ohm resistor
•Some Thin Wire
After that you’re off to the races as [William] documents how he goes about transforming the Game Boy Advance and includes a ton of great pictures and a schematic. This operation ends with [William] placing the switch for Rapid Fire excellence next to the Right Bumper where it is inconspicuous and yet easy enough to access.
