I bought a 3D pad a while back for the Saturn, and just got around to testing it this week. The analog stick feels great, but in-game it pulls to the left constantly.
Last night I took it apart and did some testing, and ran into a wall with my limited troubleshooting skills. I’m hoping some of you might be able to toss around some ideas for me.
It pulls to the left with the analog stick attached or detached. Doesn’t matter. This means the actual analog part is not the issue.
It uses a magnet and hall-effect sensors for the movement of the analog. I traced all the connections to the sensor I could see, and they all check out and have the correct voltages (to match the other 3 directions)
I finally decided to remove the left and up hall-effect sensors from the board and swap them, to determine if it’s the sensors or not. There was no change, and the issue stayed on the left direction. This means that the sensors themselves are probably fine.
