I've seen this topic a few times searching for information on Naxat. Seems Kaneko may have released it 92' as a coin op. However, I don't think there is a know cab or board in existence or even known pictures or video. . . be quite the find though.
If you search nexzr + arcage you get a whole bunch more arcade sites that list the game like those with a release date of 92', however all have no information after that.
Wonder if anyone can prove that these existed?
