Visiting unavailable Ultra Spaces

[Sodarok]

Hello everybody,

I have a question about the Ultra Spaces. Is it somehow possible to use PKHex to visit the Ultra Spaces that aren't available,

for example the Ultra Jungle in Pokemon Ultra Moon? I'm very curious about that.

Furthermore, I have a small question about PKHex. In the Trainer Info dialog, you can "change the game" in a drop-down menu.

What is it for?

 

Thank you for your help!

In terms of the Ultra Spaces all of them are in both versions.  You can find the map coordinates for each location in the thread below.
