Is there a easy way to convert this save for the USA version of the game? https://www.3ds-savegames.com/save/the-legend-of-zelda-majoras-mask-3d/after-dungeon-1
I don't own a Gateway so I wouldn't know. But what any person would do is try to see if it will work regardless if it's EUR. Remember to back up your save if it fails.
