What about titles that requires updates?

[blasteg]

I just got this working, but it tells me that the game needs to be updated to connect to internet.

Without internet connection, the game is just a shell of itself (Jam with the Band P)

Is there a way to do updates?

You can update via e-shop like your game was original and then launch the game again using the exploit (tested with sky3ds and pokemon alpha saphire)

actually no. pokemon is a special case and basically the only games for which that will work.

for most games, you simply can't update using regionthree, sorry.
