Hacking Transfer Fire Emblem Awakening save

[Aerione]

Hello,

I was wondering if it's possible to transfer a Gateway FE: A save file from a region to an another?
The transfer involves the EU ---> US version of the game, if that makes any difference.

Work. Need Savedatafiller on the 4.x CFW and need Gateway.

With Gateway, your target region (in this case USA) rom will needing to be converted to card 2.

IF you having MT, you no need convert card 2

so how is this possible? How do I carry over the 99999 renown from a JAP save file to a US save file? I tried replacing the save files from US to JAP, but when I opened fire emblem awakening, it didnt show.
