Are your hands cramping after playing your favorite game on your Game Boy Advance? Have a look at this Game Boy Advance Rapid Fire Hack by the Hackers Workbench to give your fingers a break. This circuit will simulate you tapping the B button for all you’re worth. The other nice thing about the design is since there only a few components you can just dead bug it right inside the game.

Thanks William.

“Parts list:
(1)Dual two input nand gate IC (I used a triple three input NAND gate IC because it was what I had on hand)
(1)2n2222 NPN transistor
(1)0.1uF ceramic capacitor
(1)Mini momentary on switch from a computer mouse, or similar
(1)1M ohm resistor (the value of this resistor can be mucked around a bit)
Some thin wire”
