Dear Reader:
Undertale creator officially considering port to Nintendo platforms
It's surreal that it's newsworthy that a Nintendo rep tweeted at me. I actually already talked to Nintendo about a port months ago... ^^;;

But Game Maker (what I use) doesn't export to any Nintendo platforms. In most cases, the game would have to be reprogrammed from scratch.

So I'm concerned about accuracy/bugs. I've reached the point of "might as well try it" though. This isn't an announcement or promise.

BTW, I wouldn't do the porting/reprogramming myself. It'd be up to someone else. I don't know any actual programming languages LOL

ALSO if there was a Wii U port do you think all the UNDERTALE Miiverse posts would finally have a home? Or would it just spread them more?

Well, that was cleared up surprisingly quick! While Toby mentions Wii U directly, he does say 'Nintendo platforms' in an earlier tweet, so perhaps a 3DS release could be possible as well.
