Hello all! I have an amazing modded GBA that I purchased through an eBay builder who was wonderfully communicative and built my console exactly how I wanted it.
Unfortunately, I’ve found myself displeased with one specific feature: the DPad. It takes a great deal of force to move diagonally in any game I play. I truthfully don’t recall this being an issue with my old OEM unit that I enjoyed in highschool. I added some cardstock as a makeshift spacer based on some recommendations I’ve found online, and that improved it only marginally.
Has anyone else out there encountered this issue? If so, do you have any advice?
My initial research suggests the aftermarket membrane for the DPad is the culprit. I’ve cleaned the contacts on the motherboard so I believe that can’t be the problem. If membrane conductivity is the issue, then I don’t know what brand to replace it with. Seems like every thing on the market is built by the same manufacturers?
Any advice you guys can offer would be appreciated!
I had this problem with one I modded myself because the new screen was just slightly thicker than the old, pressing on the outer shell and causing the dpad to need more pressure. The solution that worked for me is cutting a small ring of cardstock and putting it between the dpad and the membrane. It increases sensitivity by a lot, but does come with the side effect that you’ll be able to press every direction down at once if you press on the center.
I did the cardstock mod and it improved it a little, but the force needed is still uncomfortable. Does your thumb hurt after long play sessions?
Could it be membrane firmness is the issue, and not necessarily conductivity?
It could be that the d-pad traces on the circuit board have worn down over time and now the conductive material on the membrane isn’t able to make a good connection. You could try and check the traces with the continuity setting on a multimeter if you have one. Maybe very carefully going over the traces with conductive paint could help?, but I have never done that for a d-pad before and don’t know if it would work well or hold up over time.
I’ve never reshelled my GBA but having installed multiple aftermarket shells on my PSP, I can tell you that d-pad issues are very common because of bad measurements and quality. So maybe the problem is the new shell itself.
