ive been trying to resolder a SNES USB contoller board to fit into a handheld console with my old raspberry.
So now i cut the pcb and want to solder the buttons to it.
But i have never done something like this before and Im really not sure if its gonna work like this. I made some pics for you on how i am planning on soldering the buttons. Maybe you can take a look, check if its correct or maybe give me some advice.
here are the pics.



I know that there is a tutorial on adafruit, but my pcb looks kinda different. Especially that i cant find 1 common ground on each pcb, but have to use at least 2. I dont even know if thats gonna work
thanks for you help!
