I built a stickless the other day on a N52te PCB. Instead of soldering to the board like a pad hack the IDE ribbon was available and I wired directly to that. I build it similar to mame controllers people rig up from IDE connectors and Keyboard PCB.
I have 9 buttons wired to the primary board and my directional wired to the pad ribbon, it all tested fine in note pad then when I get in game I can’t execute more than two simultaneous inputs.
Is there any work around for this problem or does this sound like a limitation of the board?
