NES ZGundam?

[BFC]

In the NES guide we find the game Zeta Gundam in the rumor mill. The generally known release is Mobile Suit ZGundam Hot Scramble. But on Enri's page we find a screenshot of one of his private dumps that shows only ZGundam in the title screen. I can't read japanese - maybe it is a very rare special edition and that rumor-mill game was indeed released?
