"Hi, I just got the Reaper of souls version of diablo, the problem is that i had a europe diablo 3 save game, and the game available in the internet of RoS is US, is there a way to switch that ?" Problem resolved i got my characters from the europe version of diablo 3 into D3Uee.
You download bruteforce it's a software to open save games, it comes with a param sfo editor, take your save from the console, if it's europe change its titleID in param.sfo(it's a file that come in save game forlder, see attachement) with BLUS31437, i think it's better this way since the 1.01 update is available for the US version now so... In my case i changed the game's titleID, which mean i changed the game copy's titleID with BLES02035, hope it helps.
