"COPYRIGHT 1984 A.C.G." -- the same 21 characters Knight Lore has in the same place, just after its last routine (flip_done) and before its screen buffer, carried over with the engine: Alien 8 is from 1985, and its menu prints its own notice from its text list. Nothing refers to it (the loaded block searched for its address), and the game never reads or writes it (measured, as for BUFFER).
