53 bytes between the last part (PART56) and the sprites, not identified. No room or part reaches them, and no address of any of them appears anywhere in the game.

The first nine parse as drawing commands (two points, a mode bit, the second point, a point and a line), but what follows does not end with $E5. The last eighteen are six groups of a byte and a word, and every word is an address inside this block (four of them different, 4 to 20 bytes apart), so the block was made for this address; it may be a table left from an earlier version.
