Haunted House and Adventure both used a light radius around the player when in a maze -- you could see what was inside of your light radius, like walls of a maze, but not beyond it. Does anyone have any insight on how they did that, especially with so little ram? I mean, it's not a bullet, it's probably not a sprite... I can imagine it wouldn't be hard on a modern computer's resources but I really don't know what they did on an atari to do that. In fact I find it amazing that adventure (and certain other more-advanced-than-usual-games) were created at all on an Atari at all.
