Ok, I’ve been trying to wrap my brain around this for about 20 minutes. I’m not familiar with homebrew and such, so some of the technical jargon used has gone right over my head.
Here goes: MotorStorm Arctic Edge has been pulled from the PSN Store. Apparently there was an exploit found within the game, and by using Vita Half Byte Loader files, you’ll get a “limited PSP homebrew experience”.
Wololo seems to have already released the Vita Half Byte Loader files, which caused the reaction from Sony who removed Arctic Edge in a matter of hours. I’ve had a look through the store and the game definitely isn’t there.
I’m guessing that with the amount of piracy on the PSP, and the PS3 hacks last year, Sony will be pretty hot on this type of thing.
