I'm using a USA 3DS and will be getting the USA game. Now, since the demo is not region-locked, (It's technically the "EUR Release", though) let's say I put a header in the demo, and name it to .3dz, and once the full USA version releases, I put the same header in that one (and obviously make it .3dz as well,) Will the rewards transfer over then, since they're using the same header? Thanks!
