Yo dudes – I bought a HAPP stick recently and just a minute ago, the ground wire for LEFT on the stick (soldered onto the pcb) came loose. The PCB isn’t common ground, which makes things easy. I resoldered the ground wire back to the original position in a few minutes.
The only problem is it’s constantly pressing LEFT now. The only way to stop it is the engage the microswitch, at which point, it stops. I.e. I start up a game, Ryu either walks back or blocks (since LEFT is constantly engaged). The only way I can get him to stop walking/blocking is if I move the stick LEFT to engage the microswitch.
