So,
I was reading this one document about the prospect of Banjo getting into Smash, and this segment reminded of the unused files pertaining to Jet Force Gemini and Blast Corps within Ultimate's data.
Alright, someone school me on copyrights
I always see people's rebuttal to this being that Nintendo simply still owned the Japanese copyrights and the people behind selecting the spirits in Ultimate just didn't realize that they don't own the IPs anymore before cutting them out, but is there any actual proof that Nintendo still has the copyrights to Blast Corps and Jet Force Gemini anywhere?
Honestly, Blast Corps kind of makes sense considering that it was published wholesale by Nintendo, but JFG is a bit weird in that regard. As far as I can see, it was solely published by Rare, even in Japan. The Japanese boxart says as much.
I don't know, does JFG being "distributed exclusively by Nintendo" give them the copyright in Japan? Seems really odd that what was a self published Rare IP ended up getting mixed in with Nintendo owned properties.
