Hey, so, I remember my ORAS was in 3d for the battles, but for some reason my UM isn't. Are all gen 7 games incompatible with the 3d feature, or is this a me thing? Why?
I don't believe any areas are playable in 3D. The game case claims that some areas are, but I haven't seen a single one, in or out of battle.
Source: Lots of experience and this
Hope I helped!
