Super Giuseppe by atari2600land is a Super Mario like game for they Odyssey 2. The game is still a work in progress and develops slowly.
Release notes:
I fixed the problem I was talking about in today’s blog entry. When this new version is played on real hardware, the ship sometimes blinks. I don’t know what is causing it. Well, anyway, at least it looks better than it did. Here’s the latest binary file.
