Bumping this as it would be nice to know when Pkhex releases if changing the game version flag is possible
I'm using a save started in Scarlet that was swapped halfway through the game to Violet, and there are nuances like the online pages showing the wrong game and Miriadon having the wrong name. Also version exclusives (like Iron Bundle) can't be used online since they're considered as being caught in Scarlet (a flag that will be changeable in Pkhex, but will still affect any freshly caught Pokémon)
