Space Invaders

• EASTER EGG: The bottom 2 rows of aliens are actually the letters “RF” (for Rob Fulop) sideways (picture #1).  {Darrin Williamson TV Gamer April 1984 pg 63}

• At the end of the 8th wave, the mystery ship comes down and takes your ship.

• The game is on an 8K cartridge but it’s only 4K in size.  The first 4K is empty.

• The 5200 version (picture #2) is actually a modified version of the 400/800 version (picture #1).  The biggest changes were the elimination of the rocket, the addition of bunkers, and the different (and multiple) types of invaders.  See the 5200 section for more info.

• BUG: The cart version is not fully compatible with the XL/XE.  When the mystery ship appears, you get a high-pitched, almost inaudible tone, and no sound f/x when you shoot it.  {Scott Stilphen}

• BUG: Your shots sometimes go through an invader that’s at the lowest level of the screen.  {Scott Stilphen}
