So I got Ironhax running on my EU New 3DS, latest firmware, and can now run my old US games, but i'm encountering a problem, how do I update my games? Specifically Smash, every time I boot it up, it says I can't save because the update info hasn't been found on the SD card, it tells me to press the home button to exit and enter the e-shop to update my game, which I do, but every time I press the home button my 3DS crashes. I went to the e-shop and downloaded the latest Smash update but the same problem still persists. I even put the Smash cart and micro SD card on my brother's US old 3DS (SD adapter) updated that way, but when I put the SD and Smash in my EU New 3DS it still says that the update info is not found on my SD. Any idea if it's even possible to update US games on a EU 3DS?
