Super Vaders is an expansion on the massive arcade hit Space Invaders. The basic gameplay is exactly the same (except that the screen is turned sideways), but there are options that you can enable/disable and mix to create unique games in their own right. This includes guided bombs, diving invaders, exploding bombs, and guided missiles.
The screenshot above for the options screen has some garbage at the top; I believe that the game was meant to run from a cassette system only.
