Game Sync issue with JP White 2 save into US Black 2.

While I could easily make the Friend Code differ, the same cannot be said for the Game Sync ID. I know that the Game Sync ID can't be changed on the same save file, but I want to use Game Sync in Black 2.

You won't be able to use it on the U.S.\European Global Link, even if you do transfer the save to US Black 2. It'll probably work on the Japanese Global Link, though.

Oh well, the problem has risen again as I tried to move on from US Black 2 to JP White 2. On both DS Lites I get the error message saying something with two instances of "1" and DS. I can't play Dream World no more.
