Sony Xperia - Recording / run games off the internal memory of the phone?

view story

http://forum.xda-developers.com – Good morning, I have a Sony Xperia Miro with 2GB of internal memory available to the user, but after I realize that I record every game must go to the folder mnt / sdcard / android / data. As already installed some games "heavy", I start to get a little limited to the internal space. I have a 16gb class 10 card I bought to install applications and games, among outas things. The phone is already routed. Is there any way to set default date of the reading of the games to the folder mnt / ext_sdcard / android / data (which is my external card)? Grateful in advance to anyo (HowTos)
