GBC Buttons all stopped working...

[Super Cameraman]

A while ago I was messing around with my Gameboy Color, trying to wire an NES controller to it, and it almost worked, but I desoldered everything because I had no case solution. Now, it still turns on and the game still starts and the sound works, but none of the buttons work. What could be the reason?

just do the opposite to what ever you did to it.

I did... everything is the way it was, but now the buttons aren't working.

Anyone have any more ideas? (Over a year later, I know... Hahaha)

Still can't wrap my head around this. I can even directly bridge the contacts for the buttons and the Gameboy won't respond at all...
