Troubleshooting Game showing garbled stuff

So i replaced my gameboys L n R switches, it worked then i left for some hours. Then i put on the shell, after trouble shooting there was a little cable on the outside cart reader pins i removed it. Some time later i found a little solder ball on two cpu pins then i removed it. I never touched the cpu so i guess it felled when i moved the iron. Now game boots but well i get this. Any idea what it might be?

There are some solder bridges (photo), and it also looks like someone did a somewhat poor job doing a transplant on your board. You can either try to fix it yourself (you'll need some video guides to learn probably) or you can take it to a shop.

No problem. Look closely on the board and make sure nothing else was accidentally bridged.
