Hi, dont know why the game does not want to have the Perfiles.DAT decoded, but in demo you can check for all the info found in perfiles.DAT, most important are the user statistics for medals and mission unlocked/completed.
This is the fille format decoded so far:
Perfiles.DAT: Header (String) 0REP Login counter Int32 Last difficulty Int32 Last user id Int32 Mission unlocked Int32 Profile name lenght Int32 Profile name (string) to lenght Difficulty Int16 Medals (1 to 8) Int16 Mission completed Int 16
