I noticed that it now restarts the DMG when wiggling the cable. This only happens with 2 of my dmg's other 2 are fine...

Maybe something inside is shorting when link port is bent or something like that ... any idea's ?

It is a function of the dmg to have this pin controlled over the link port, but I can't think of any official or even homebrew application that utilizes it. Whatever cable you've bought must for some reason have this wire present.

Your link cable must be connecting this pin to something it shouldn't be. I suggest actually removing the wire on pin 4 from your cables if it is present. Can you open one of your cables and find out?

Yeah if I plug everything in, all works fine except the dpad, then when I lift the plug from the cable a bit up or down, or when I just put my finger on it and apply some pressure the dpad starts working. So problem would be inside the cable then ? Not my dmg's ?

So I've been getting me some gameboys and a link cable. I was lucky to buy 2 nanoloops 1.5 a couple of years ago and forgot about it till now. But i'm having a problem with one of my DMG's when I plug in the link cable in both dmg's the d-pad stops working on one of the gameboys. When I apply some presure on the connector it works fine.

Any idea's what the problem is here ? I have 4 gameboys laying around and 2 of them are having the problem
