There are some severe bugs in this core still. In Final Fantasy 9, areas randomly have corrupted graphics for their backgrounds. If you leave an area and come back it often fixes it. The movies often have a vertical band running through them that appears to be portions of the video from seconds earlier. Also, the overland doesn’t render correctly at all, most of the screen is black, making it impossible to see anything.
This only happens with the hardware core with ogl enabled but the same thing happens on both my computers with very different graphics cards
