Ok
@aldostools I tested new app, and it seems to work fine, excluding that I wasn't able to make working configs with game ID at end (so almost full managunz archive). I think this is not app problem itself, but I need to make more tests to be sure. For now I can say it successfully encrypt config, and add it to pkg. So all that app is suppose to do, is done correct.
Note to anyone who want to use new config option:
After downloading config, open it in hex editor, and remove game id at end of config:
Before (game refused to boot, return to xmb):

After (that one worked for me):

So
@aldostools good work! I will made some more tests when I will have some more free time. But one working config mean that all of them should work perfectly fine after removing ID!
