weird copy of ice climber

[Xcursion666]

So I recently bought a bundle of Famicom games from Japan and one of the games is ice climber along the way in the mail the shell for ic popped open and board was loose the board says hvc-nrtom-01 no Nintendo markings the weird thing is the cart shell itself look 100% legit and match my friends real copy to a tee
now I was told it was a ntdec board elsewhere but I have a few other ntdec bootlegs already and the shells don't match
