The enemy layouts in the two sections of the final round, Doriasta, come together to form the phrase "インベーダー９０" ("Invader 90", part of the game's Japanese title; the ー after the ベ is underneath for some reason) in the Japanese version and "INVADERS" in the US one.
This in turn leads to the two versions having different amounts of enemies: 32 and 40 respectively in the first section, 42 and 41 respectively in the second.
