I have a problem with two of my Controller Paks (Original Nintendo):
The N64 says it's damaged or corrupted and it offers the option repair or restore. But that doesn't help at all. I tried with Castlevania and Turok. Seems to be the same with every game.
I wanted to change the battery because I thought it might be empty but if I measured correctly it is not. I have not exchanged it yet cause it's soldered and I wanted to ask here first, maybe someone has another solution for this?
