This appears to be caused by one of the two backgrounds it flips between (which are in theory identical) having a small region of the background blacked out. This causes the flicker. I haven't yet tracked down why one of them has that line blacked out. |

This happens because a VRAM DMA into OBJ RAM overflows (goes past 0x06018000) and wraps back around into the mirrored extension of BG RAM (0x06010000+). Will need to do hardware tests to see what the right behavior here is. |

I tried the japanese version of Aero the acrobat "Acrobat Kid (J)"
with mGBA 0.5.2 and latest nightly 0.6-4531-29d1da6 (Windows)
Just in title screen, pressing start appear a black line flashing.
