Beeshu Zipper help!

[defghui]

i just got myself a beeshu zipper on ebay, blue one, for about $8.

it looks great and all but... its not functioning correctly!

the select button only works when you hold start
the start button only works when you hold up
the B button only works when you hold select
the A button only works when you hold B
none of the directions work

am i going crazy or is there a possible fix for this? im using it on my top loading nes2. i dont really want to throw it away or return it or anything, i just want it to work properly.

any help would be appreciated!

I don't even know what that is, but what you describe (at least for older controllers) sounds like the ground line could be messed up. Try tracing the ground with a multimeter and make sure it's properly connected at every point where it LOOKS like it should be connected.

What I used to do was clean these old controllers up by dismantling them, and scrubbing the contacts with windex and paper towel.
