When enemies are behind corners or objects, the object blocking the enemy from view flickers for some reason, showing the enemy sprite. Tested several video plugins, same result. Anybody running Disruptor with graphics that are all right?
You know what. That actually happened during the real game. It's just part of the game bugs. It's nothing to really worry about. I remember because this was one of the first games I ever played on PS. Unless it gets really bad, just try to ignore it.
