Nightshade: Data at E600

E600: The tail of the loaded block, left behind by the move (inside the buffer)

The tape loaded the game block 512 bytes higher than it runs, and the loader unscrambled it there and moved it down to ENTRY (LOADER). A move leaves its source behind where the two do not overlap, so these 512 bytes are a second copy of the game's last 512: from the operand of the first CALL in DRAW_SPRITE_AT (DRAW_SPRITE) to the end of the buffer's first 60 bytes -- byte for byte the same (compared in the snapshot). Part of the buffer: cleared before it is read (SHOW_PLAY_AREA), and never run.
