Ois: I still see DK2 around under the 'black diamond' (aka Rainbow Products Entertainment) packaging/distributor now & then. Usually in the budget bin if you want to avoid e-bay.
Ah, I haven't seen a copy of DK2 outside of eBay in a long while, but that might be because I usually only frequent EB Games. It's probably a good thing I don't drive, otherwise I'd be game shopping all over the place.
I couldn't find the unofficial patch, which makes me wonder if there really ever was one, or whether I confused it with this
patch.
If you ever feel the inclination, you should check out DK2 again, and hopefully, you'll have better luck. It's well worth it.
