Upon booting up a pre-owned Vita title, players will get a screen that reads, "You cannot earn trophies in this application. Only the first player to use an application can earn trophies. To earn trophies, you must link the Sony Entertainment Network account of the first player to use this application with the PS Vita system." Pocket Gamer says the following steps will render that warning useless:
- Go to the main menu and hold down the screen for two seconds, until little bubbles appear on the upper-right side of each game's icon. Hit the bubble you want and click "Delete."
- A screen reading "All data related to this application will be deleted" will pop up. Hit "OK."
- Load the game and you should be good to go.
