Sony saw brighter pastures when they issued fixed versions of Motorstorm Pacific Rift and Hot Shots Tennis. Initially, those two pieces of software, when played on a Vita, allowed an exploit which let hackers run Vita Half-Byte Loader (VHBL). Within a day of Sony discovering the game was continuing the hacking community to continue, Sony pulled Super Collapse 3. If you purchased the title and deleted it for some reason, you cannot download it again to play until a fixed version is issued. Welcome to digital content!
The community claims the exploit didn’t allow pirated software to run, just unsigned code. However, after being burned by piracy on the PSP, Sony is clearly looking forward to close down these loopholes before they expand into a black hole they can’t climb out of.
