QUOTE said:Snowball Blaster has 128 channels of Light-o-rama controlled by a PC. The game logic is running on a Basic Stamp which accepts inputs from the player switches and controls the Red Arrows with sold state relays. The BS also sends logic level triggers to the LOR system for Game start and Crash. The snowballs, scoreboard (and the rest of the light show live in the LOR program.) There are separate LOR programs for Attract, Crash and Game play. The BS knows when the snowballs reach the bottom, and compares that to where it knows the Arrow is to detect crashes.
The game is designed around the limitation of having very few positions to light up. The timing of when they light up is more versatile, so that's where the game lives. It's easy to learn, starts easy and gets harder pretty quick.
When I saw the title I thought the guy had made a grid out of Christmas lights (each light representing a pixel), and ran a Gameboy emulator on it
