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.

YIKES! That is the gobbiest ugly solder mess Ive seen in a while. Maybe this is better suited for “kludge-a-day”?
seems like “glued” not soldered ;)
but nice idea also
Agreed. Those solder joints need work.
“Save that sore wrist for something else” I lolled.
always nice to see more freeform solder jobs :P
Good to see some very simple electronics hacks from time to time!
“A couple NAND ICs”? I only see one.
second one is buried under the solder.
There was a similar thread on rec.games.vectrex just recently. Here’s a circuit with just two transistors which might work on the GBA with some tweaks to the values: http://groups.google.com/group/rec.games.vectrex/msg/806a33aa9557a19a?dmode=source
@johannesburgel He uses a single IC with 3 NAND gates
I remember taking the small autofire circuit from a joystick and putting it in my Amiga mouse, with an on/off switch, so I could have autofire on Star Wars.
Ahh those were the days…
A better way would be a small micro controller, have it monitor the backlight button. If it senses a button pressed while holding the backlight button down, it triggers auto-fire on that button. Same method for turning it off. Should only take the same number of parts and maybe a 3/4 extra wires.
