Summary	08695: opwolf3 and clones: Muzzle flash of gun in attract mode has wrong colors
Description	During the attract mode there is a sequence prior to showing the title that involves a flashing eye/pistol. As the pistol zooms away and turns, it fires and there is a large muzzle flash graphic. It should look fiery but instead looks like a mess of unrelated colors. There's also black dots on the map screen during the demo that appear at times while the screen is panning left and right. They show up for a few seconds at one point where the screen stops. That image will be attached below the video of the issue.
Steps To Reproduce	1. Run opwolf3. 2. Hit F3 to reset if it's the first time you've run the game (the game always first loads upside down and the initial calibration screen is missing text, but that's another bug report) 3. Let the game run for about 2 minutes (hit Insert if need be). Eventually you'll see the game plot/summary and the flashing eye/pistol screen. Watch the explosion at the end (could also just hit P here, and then SHIFT+P to step the frames 1 by 1).
Additional Information	Real footage from a board Luke Morse repaired.
