Sorry I haven't worked on my gbz in a while but I'm starting up again still confused what to do about this, here's a picture of it

I was just modifying my screen to use five volts, however I can no longer get wires onto it because the metal where I removed the chip has come off and there's nothing to connect to

So the black piece that I have to take off of the original controller board got stripped on my first attempt and I can no longer get a good grip on it with anything. Anybody know any other method then the glob of solder since I burned myself last time I tried that way.

I just used tweezers to rotate it enough then gripped with my thumb and rotated the whole cart, it's pretty easy
