So I have two versions of Xenoblade Chronicles, and I want to know if it is possible to transfer my save from 1 of my files, to the other. If so how do you do it?
If two versions of a game have different game IDs, there is no simple way to carry over save data in the general case.
If it's just the gameID you could just rename the folder in /title/ to match the other game ID.
Or you can use Wiimms ISO tools (wit edit game.iso --tt-id=XXXX) to set the savegame ID for that game to XXXX (of course you'd need to replace that with the savegame ID of the other game).
