Of course.
A less destructive and simpler solution would be to use a SPDT switch and add a resistor, but I haven't tested this.

If I knew the values of said resistors I'd love to do this for science.
EDIT: I see why a SPDT now whoops lol

Resistor removal is optional, you just need to break the traces. Keep in mind this will destroy the L and R functions for typical GBA use.

Whoaaaaa hm.

Wouldn't it be possible to wire up a DPDT switch and have it toggle either button function (L+R = L+R, L+R = Select+Start)?

I think Bitman will be finished with some tutorials about this soon.

I see. Basically I would never have figured that out myself, and am crossing my fingers that someone can tell me which resistor, and where to run the jumper. I can solder pretty well, but usually have no idea what I'm actually doing without pictures or specific directions. Inquiries about this mod seem to come up from time to time, a description here might but a useful for amateurs like myself. Initially I just tried soldering the two side pads from the pcb for the select button over to two posts on the shoulder button. Not working.

Yes. You have to remove a shoulder button resistor and run a jumper wire from the select button to the shoulder button pad I believe. Forgot the exact resistor though.

Does anyone have some instructions for how to wire this up? I know it's possible, and probably super easy, but the old asm tutorial is missing in action, and my attempt to work it out myself was a solid failure.
