SPACE INVADERS
• 3 different PAL versions exist. The 1st version (picture #1) is a matte-label style and runs slower than the NTSC version (like most PAL conversions do). The 2nd version (picture #2) corrects the speed problem but introduces a glitch that affects the controls of 2-player games #81-#96 (the shots alternate between the players, but the movement doesn’t; only the right player moves the cannon). Also the colors are darker (and still incorrect). The 3rd version (picture #3) corrects all these problems.
• The SECAM version displays the first and last digits in both players’ score counters in different colors (picture #4).
• BUG: Holding RESET down while turning the system on gives your ship double-fire (picture #5 and video). {Bill Heineman, Oct. 1982 Electronic Games, pg. 38; Paul Geisler, Sept/Oct 1982 Atari Age, pg. 4}
• FRYING: Fry the game until the UFO flies by. Start the game, and you'll have double shots. {Jens von der Heide}
