It’s a Chinese stick made by Sitong. It has been dodgy for a while, I can use it for about 10minutes and then it will stop working and not work for a long time. Stick and buttons are Sanwa and everything is soldered onto a 360 controller psb.
I took it apart today to see if I could figure out why it would stop working. While I was handing the pcb I noticed that the black box thing over the start button was burning hot. The box is circled in the photo below. Any idea why this might be? Anyway to fix it?

If I don’t manage to fix this I may just put a cheap pc psb in there to use the stick with emulators.
