Poor little Kangaroo. All it needs is a bit of love.
If distance, money, and spousal harmony were not factors, I'd buy that. The artwork looks great and that chipped off side should be easy repaired. If you can't find anyone to trade it off to at least try to keep the sideart intact.
I didn't realize there was such a vocal anti-Kangaroo base out there. Sure it has finky controls, shoddy hit detection, and is basically a Donkey Kong knock-off, but it's still not that bad. I have fond memories of playing Kangaroo at Santa's Land in Cherokee, NC.
EDIT: Just noticed the start buttons are missing. I'm guessing someone parted them out because nobody makes those volcano buttons Atari used?
