1. That is not a repro, that is a homemade cart. somebody put together. A true repro, is a duplicate of the original.
2. I did encounter F-zero 2 on the net for the Super Famicom, It has a box and everything.
3. F-zero two just has slicker looking everything. One of the reasons why it was never released, in the west. The soundtrack is the biggest difference, and track sizes, I think.
Of course I can't think because I am Mameless. I am thinking about that, now........you know terms.
I love the N64 F-zero, it is just right, for a 3d game. The GCN got the shaft because they took out a feature, in the west version. I would play F-zero on Kal.
