so, i signed up to be a developer through Nintendo (its free, apparently you just need a developers device.) Apparently you can create content with html5 and put it on the Wii U. So, the question becomes, how to do this from RPG Maker MV and is there any legal issues i should know about?
As for "how to do this", bear in mind that there is no
direct way to do it. It isn't like Unity where you might select a platform, such as iOS or PSVita, and export it in that platform's native format (before anyone jumps in, I'm well-aware that there is more to switching platforms on Unity than simply selecting another platform; I just mean that the option exists).
My best understanding (
someone please correct me if I'm wrong, as I'm keen to know this) is that all RPG Maker MV games are essentially HTML5 games; just if you export to PC/Mac stand-alone, the game goes inside a "wrapper". This means that if you wanted to convert to a non-supported platform, you would export to HTML5, and then you would need to create your own wrapper for the platform, and potentially have software to recompile the game for distribution.
Also, be aware you would need to write plugins and make changes to your game to satisfy Nintendo (or Sony's, or anyone else's) submission conditions. This would mean you'd need to display WiiU button icons on the menus, have the correct order of events on starting your game, along with a variety of other conditions.
I'm not certain about legal issues; someone else hjere might have a better idea about that. However, the above steps are a pretty big undertaking if you've never worked on a console game before.
I'm not saying "don't do it"! If you're really keen and you want to bite off that big task, then go for it! Just be aware it's pretty involved.
