Description

For some reason, during Quartet's initial load, the border briefly flashes with dark lines. Investigate and document why. (Note: if the bugs ends up fixed on that download page, it's still present in the cracktro.)

Tip: the bug reproduces on Mesen-S, which has both a GB and SNES debugger, so it should be easier to figure out.
