Enforce

Even if the title screen says 1988, Enforce was released in April 1989 in Japan.

Despite that late release, the high score is anonymous.

Even after you complete the game, you'll get a game over screen after the staff roll, just like in "Continental Circus" or "Chase H.Q.".

World and 2 Japanese ROMs have non-metric units: foot and inch for length, height and width along with pound for weight. Only the gun is measured in a millimeter. All 3 ROMs have English speech. The engine in all 3 ROMs is a diesel 12V turbocharger. It's not known whether it was meant to be a V12 engine (12V means 12 valves; V12 is a type of 12-cylinder engine with pistons shaped in a 'V' letter) or a 12-valve one.

'Special thanks' are misspelled as 'Spacial thanks'. 'Laser cannon' is misspelled as 'laser canon'.

World rom is licensed from U.S. Navy under U.S. Patent 4,021,846.
