How to transfer EUR save data to USA game?

All you have to do is rename the save folder. This will not work with all games especially when one version was updated while the other didn't and for whatever reason save format changed, but for many including GE series it will since PPSSPP doesn't cry about it like real PSP would.

I just wonder why did you get 2 western versions since GEB EU/US trully is same game, works same way and even has a crossregion multiplayer.
Only JPN version of GEB differs as it got more updates and dlc's.
