Trying to update Cube Creator 3D on an OG 2DS, and other updates worked fine, just this one doesn't. If it helps it is a .cia, and so are others that I have, but those ones updated no problem. Any ideas on what the issue could be?
I can't say, what exactly the issue is. But u can also update games manually. So simply go to the internet, and search for the updatefile and install it like a cia.
I think it's not allowed to post links to such websites here, so just a tipp: You can often find the updatefiles, where you can also find the game files
