I am having an issue where my GBA sp is not loading original gameboy games. (The seller told me about this I am trying to learn soldering)

First time I tried tetris it tried to load but the nintendo logo was messed up. I took it apart and cleaned it thoroughly.

When I tried tetris again the nintendo logo was better, not perfect, but the game won't load still.

Is there a chip on the motherboard that is potentially responsible?
