Alfred Challenge

This game works on NTSC, PAL and SECAM. The difficulty switches control the pallette and scanlines. As far as we know, this is the only VCS game with such a feature.

As part of a contest by Ebivision, there’s a secret room/screen hidden in the game, and the first person to find it won a copy of their unreleased version of Pac-Man. Jeff Rothkopf was the winner.
