uaflag: turn your screen blue and yellow

Post by tepples »

When you play on a Game Boy, you have to move neck to get the light angled to see anything. But when you crane it just right, you see this.

This short program displays the flag of Ukraine (or Lower Austria), top half strong azure and bottom half yellow, on a Super Game Boy or Game Boy Color. (The original Game Boy's screen is dark cyan to light yellow with greens in the middle. This ROM gracefully degrades to such conditions.)

Also for Game Boy Advance. Tested in mGBA and on a GBA with GBA Movie Player.
