Yeah, that's a pretty ancient browser at this point, I can imagine that the forum is not quite at home on it..
Yep, the machine itself is a bit old. I'm assuming you didn't take my comment seriously, but either way, don't.
I would agree with this one. Red-label Donkey Kong seems about as common as red-label Donkey Kong Junior and I don't see either very often. 4 is about right for both, in my opinion.
Also, I would suggest bumping the 7800 picture-label Pole Position 2 up to at least 3. It's definitely not as common as the text-label cartridge, and in my experience isn't anywhere near as easily found as the other 7800 2's. The boxed version of Pole Position 2 is of course fairly common, however, not all boxes came with a picture-label cartridge inside, as I found out when I bought one from Big Lots back in the day.
I suggest bumping up 2600 Super Baseball some. Not ever seen in the wild anywhere, and not common in someone's collection.
