Got a few more gems in today, including 2 more unreleased NES games:
First up, Airball:
Obviously, most have you are familiar with Airball after BunnyBoy made it famous with his first major Retrozone repro release. This one is cool for a few reasons. First, it is a VERY early build and completely different from the version Bunny released. Although early, it is still beatable (I actually beat it minutes ago). It does not have a difficulty option, so it's one hit and you're toast this time around. No floating ability and you can burst from over inflation. the one thing it DOES have that the Retrozone version doesn't have is the ability to change the configuration of the D-Pad movement. You can set it to "Diagonal" which is the set up you have in the Retrozone version, or you can set it to "Normal" which allows you to move up and down and left to right.
Next up, Star Trek V: The Final Frontier:
After reading all of the hate about this game, it's honestly not THAT bad. Decent graphics and platforming aspects, it just doesn't seem polished. I can forgive it for that as it never saw release. The game definitely has a tough learning curve, but I found it enjoyable enough.

I also picked up a proto of James Bond: The Duel for the Genesis with box (what appears to be a photocopy of the final art), but I'm just not excited enough for it at the moment to snap a picture.
These two games bring Matt and my total of Unreleased NES games to 16! Not bad for a couple of Science Teachers

Wanted to give a big thanks to Portnoyd for hooking up my brother and I with some sweet deals. Thanks so much man, we really appreciate it!
