Hacking mortal kombat mod question

[G36cBossMan]

i was looking into mk9 mods for ps3 such as the boss mod to play as boss characters i looked in the mortal kombat vita directory and noticed it uses the same.xxx files used for the ps3 mod i want to try in on the ps vita but am worried about a brick could this brick my ps vita or is it worth a try?

Edit: doesn't work gives me an error and says something about files in the data directory tried deleting the files and loading the game again but it gives me the same error and makes new files in the data directory would have been sweet if it did work playing as boss characters
