I own this cartridge, and it is not listed in the current DP Guide 7. Only the CBS re-release is listed, but there was a K-Byte release first (as was with K-Razy Shootout), and the model number for this cart is ATR-1001. I cannot comment on the rarity, but I have only come across one (the one I own) in quite some time of searching amongst various collectors and ebay, so it can be considered quite rare I suppose.
