iirc, they got broken when we passed in video_update from

Code
	for (y = cliprect->min_y; y <= cliprect->max_y; y++)
		snes_refresh_scanline(screen->machine, bitmap, y);

to

Code
	for (y = cliprect->min_y; y <= cliprect->max_y; y++)
		snes_refresh_scanline(screen->machine, bitmap, y+1);

(notice the y+1). I've never gone back to fix them wink
