Looking for Famicom sidescrolling platformers NOT released for NES, prefer legit

Hi. I'm after Famicom games of this sort. See topic title. The closer to Mega Man 2-6 / X1-X4 in general structure, gameplay mechanics, and production values, the more I'll be interested! Minimal Japanese text is also a plus. I'd generally rather have genuine carts where feasible. Of course some may be expensive enough to make pirates OK.

Not too familiar with Japan only Famicom titles so I don't have a list to go by. Thanks.
