Hello! Scoured the internet and finally seem to have found a forum dedicated to the consoles of old. But anyways, my dilemma is with an original SNES controller in my possession. There seems to be a problem with the IC on the board, which in this case is a v502B. The symptoms are as follows:


X, R, and Select do not respond
Certain games will freeze until I remove the controller


I've attempted to factor out any other variables by switching cords, buttons, rubber pieces, and ports; the only constant is the controller board itself. I've cleaned it thoroughly and completely, so all that leaves is the chip. However, I don't know if this piece is replaceable. Internet searches have come up dry, and any info I find on the piece says that it has been discontinued.

Is there an alternative chip that I can use for this controller to replace the v502B? Is there any way to fix this chip problem on the controller, or am I simply out of luck here?

gawd man...buy a new controller you have given me a headache just reading all this dribble on the controller you can readily pick up for under $5 if you know how to hunt and sometimes much cheaper...

If there's a way to repair it, I'd like to know instead of tossing it out or simply keeping it for spare parts.

You might have a cold solder joint or a broken trace. Anything else, in my opinion, is not really worth the trouble. Surface mount components are a bitch without good tools. However, if you really want to go through the trouble of replacing the IC, you can use two NES encoder chips as a substitute.

I've been looking at the chip and thinking that the leads look good, but it might be worth a closer look. Thank you!
