As I've noticed you can't update US game rom on EUR console (it downloads, kinda installs, but with no effect), so you are forced to stick with roms of your region, if you want to keep your game up to date. But the think is I have a savegame for a nice little game Azure Striker Gunvolt that I don't wanna go to waste. The game has 1.2 update with new content, but I have no way to install it. I can't update it by normal means and I can't find a pre-made cia file. Is there any other way to update the game in my case?
