I'm curious because I can't find anything about it

Sure, why not, any game is runnable. I think some people toyed with the idea when it first came out, but I imagine the lack of documentation on it is due to lack of interest. Feel free to be the first.

I'm new to the idea of speedrunning FF6 so I just wanted to make sure.

I figured this would be a good spot to ask. I have a completed run of FF6 any% glitchless for Steam now. Will that get a board?

I could see it being a miscellaneous category. Would be cool to see that as well as 100% categories on the board, even though sadly very few people run it.

i can make a board just for you if you want it. It is an official release, something very different but defenitley not Misc, would have a main board
