Valkyria Chronicles II

[nvrbnacmp]

heya guys, i'm trying to play this on an iPhone with iOS6

and, everytime i let the game saves on the memory stick, it loops into "save data corrupt", "delete the save data", "create new save", and it says its corrupt again..
so far i've been able to play, and use the save state, but it'll be much better if i can solve this memory stick issue...

so, anybody has a clue?
thanks..
