Hmm... I'm noticed that is Metroid game wasn't released in Japan on Cartridges, only as FDS game (at least there is no known Metoroido (J) dumps out there)...
I know that is Jackal (U) was released in Japan as "Red Forterss" only for FDS... And so on...
This is not counting FDS only games that wasn't released as cart versions at all...

I just curious, there is exists any info or List of all such games that wasn't released in Japan for cart system?

There is another one thing interest me, some games carts was ported from FDS to carts by pirates like Whirlwind Manu. Like well known "SMB2", but there is a a lot another conversions... I wish to find info about most of such conversions, for now I didn't know exactly which carts and games was ported from FDS since they undumped or unknown for me at all, only thing i can that is suppose ;) ...

I recommend these as starting points:


This is a list of Famicom cart games -- it'll tell you what's "Japan only".

This is a list of FDS games. You'll have to cross-reference this with the Famicom cart list to see which games are exlusive to which mode. It'll also tell you which are Japan exclusive.

Soon enough, www.famicomworld.com will have more comprehensive games lists, but right now the site only has the same information you'll find at the above links.

Biomiracle is probably the second most famous FDS to pirate (Baby Mario) after smb2j.  I've heard that there is an official Biomiracle cart too, but I've never seen it.

Yeah, it's supposed to be very, very rare...
