Dual Mod problem

Tech Talk
#1

I connected a madcatz pcb to a ps1 pcb. When I connect the ground wires, the pcb of the psx shows me that most of the buttons are staying activated. And the rest are going off and on. The madcatz pcb is just fine.

Any Ideas?

EDIT: Sorry please remove this thread. I didnt meant for it to post. I typed up the post but decided not to post it. I guess it went through because Im an idiot. I did figure it out though.

You might want to be more detailed on what is happening with the psx pcb. Are you sure you didn’t solder a ground wire to a button’s signal causing it to be always held?

You violated a golden rule.
