Summary	01350: rthunder: Graphic glich of the door.
Description	About Rolling Thunder door glitch: - Spriteram buffering fixes sprite lag, but causes a glitch in rthunder when entering a door. The closed door is made of tiles, but the moving door is made of sprites. Since sprites are delayed by 1 frame, when you enter a door there is one frame where neither the tile-based closed door nor the sprite-based moving door is shown, so it flickers. Given the experience with Baraduke, where a glitch like this is apparent in the floor 6 boss, this could very well be a bug in the original; if it isn't, I wouldn't know how to fix it.
Steps To Reproduce
