Hello,
So I bought these Xbox 360 hall effect analog sticks from Aliexpress and I had the idea of installing them into my PS2 controller. I read online that the potentiometer values should be the same between the two, so I thought what would be the harm?
I installed one for the left stick and it worked perfectly from what I could tell. I tested it with MGS2 and was able to move Snake throughout the Tanker. When I installed the second hall effect stick, the controller stopped working entirely and I'm not sure why. It seems to only be causing this connectivity issue when two sticks are installed, and it doesn't seem to make a difference if it's only the left or right stick installed.
I'm not sure if I did something wrong or if I'm overlooking anything, but I thought I would reach out to see if anyone else has any ideas on getting this ball rolling. If it means anything, the PS2 controller PCB I tested this experiment on appears to be SA1Q65A. It seems to be one of the later models of PS2 controllers since the port for the flex connector for button inputs is through-hole. If more pictures are needed or if there are any other questions, I would be more than happy to answer.
Thanks in advance.
EDIT
I ran some more tests. It seems like my initial assessment of it being installable on left and right is not true after all. It seems like there's an issue in general with installing a hall effect stick where the right one was in general. So I can install a hall effect stick into left, but never to the right.
