D500: Room 0x15: Ballroom West (teleport: 1359)

Used by the routine at 8912.
The first 128 bytes are copied to 8000 and define the room layout. Each bit-pair (bits 7 and 6, 5 and 4, 3 and 2, or 1 and 0 of each byte) determines the type of tile (background, floor, wall or nasty) that will be drawn at the corresponding location.
