I'm still hoping for an official release for this one, in collaboration with the original programmer (where he tunes it up and adds a bit of polish here and there like a difficulty select, maybe a tweaked scoring system, some minor additions/improvements to animation/sprite graphics, etc.). This is one of my favorite 2600 games of all time, and to think that it nearly never saw the light of day at all (that would have been a tragic loss, IMO).
