TropHAX is a plugin that will unlock all trophys in any psvita game
after installing to *ALL or *TITLEID simply start the game u want to unlock trophys in,
once your at the main menu, simply press START+SELECT to enable the plugin and L + R to start unlocking trophys
this may take awhile but once it returns you to the game it is done unlocking
Trophys will sync online. so theres a potential ban risk,
use another account, or simply use offline if you care.
