Hey all, any idea what could possibly be wrong with this board?

The issue is really weird, as it one only seems to appear briefly after the high score screen loads on my KoF 97 cart. Cart works fine on my other boards, NeoDiag claims there are no hardware issues on the board, and not obvious signs of trace damage...

Video of the boot sequence. Boot logo and sounds is clear, high score screen are garbled, intro movie is clear:

Check the traces under the pcb that go to the GRZ, also check the pins of the GRZ
