I worked all night on this, trying various things to make it work. But I think I did it. I added walls to bump into. I only kind of understand the code for this, though. What is really perplexing is that the code table for the rules of the maze has 15 rows while the actual maze has 20, yet it all seems to work together some how, in a way I don't understand. It's like Ms. Pac-Man for the 2600. I tried the game out with maze on a real Game Gear and all is good. It's 32 degrees and 6:30am here. But there's no snow. So anyway, here's a picture of the game in action. The file to download is in the "another Game Gear game" topic in the Homebrew section of our forums.
