need help with psx hack
IguanaStorm:
the pcb im using is just like this one http://wrongcrowd.com/arcade/pics/eapad.jpg
. the guides ive found dont show where to solder the buttons on this type of pcb. they only show where to solder for the D-pad. any help is much appreciated.
Bgnome:
you can solder ANYWHERE. just follow the traces and pick a spot. you can solder to the pad area or directly to the trace. the idea is to just close the circuit to ground, so it wont matter exactly where you solder as long as it is continuous with the correct trace. just scratch it up a bit so the solder sticks and youre as good as gold.
IguanaStorm:
how do i tell which is the ground trace?
TalkingOctopus:
Ground will connect to each button so if you can trace a wire around that attaches to multiple buttons it is ground. You can also use a multimeter and test for resistance (ohms). If there is no resistance (0 ohms) between 2 contact points of different buttons then it is a ground. The ground is visible on that picture.
- For the Up & down buttons, the ground is the left contact.
- For every other button it looks like the ground is the top contact.
You only need to solder one wire to the ground and then daisy chain it around to all of the arcade controls. Any of those points will do.

i tried soldering to a trace but it was so sensitive that it peeled right off the pcb. maybe it got to hot?
