virus for nes?

[Enigmus]

What Tootai states is true. The first copy was sold cheap as a "Tetris" prototype without being tested. It was then resold to a European proto collector.

This is at least the second copy, but I'm pretty sure it's actually the third. Dream has said:
"an internal Nintendo development studio for strategy guides which has been known to produce some pretty rare finds (Virus was found at this same studio)"

I'm assuming that he was referring to this title, although I could be wrong.

Let's hope a community member buys it and dumps it for further study.
