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.
