This is pretty dang impressive.
What's next? Radar Scope? Monkey Magic?
If you don't know the history of this game, you're not alone. The article really downplays it - details are scarce, but the common belief is that there were only ten units produced and they were never officially released - the game tested poorly (for an arcade shooter, it's rather slow with some poor design choices that lead to long 'down time' waiting for enemies to move so you can complete the levels). This isn't just a 'lost' game - this is like the hidden grail of the Arcade community (well, one of them).
There was some renewed interest in this title of late thanks to the Sky Skipper Project and their work done to faithfully recreate a cabinet, down to the last details. I wonder if this played into Nintendo deciding to dig this one out.
Curious if they'll leave the "Damn it!" in for the release.
