So I decided to plug in my Odyssey 2 again. This after I discovered I had been working on a version of Explosive Diarrhea for the Odyssey 2. I looked to see what the current version did. I couldn't move. So I looked at the code. The moving the guy code was in there. So I reset my computer and tried it again. It worked. So I did a few updates. The main part of game logic and movement were OK. I added an outhouse for the guy to go to when he's done crossing the minefield. This is how the game looks on real hardware. Aside from a few nasty bugs which turns the high score number (in black) to 31 for no particular reason sometimes and the grid flashing for a split second, everything looks OK.
