I’m deep into the console preservation, restoration, and modification scene personally as an active contributor, and in talking to another friend in the community tonight around this article, it wouldn’t surprise either of us if most if not all of the exploits from the link were happily held in community embargo until a safe distance after the date Sony officially discontinued its support for the Vita had passed. There’s been a real flurry of “jailbreak” activity from the community since Sony decided to walk away from the Vita, despite some niche third-party manufacturers like Limited Run Games still supporting the system with new physical releases.
That said, while the Acekards and R4s made the Nintendo DS by far the most accessible vector for piracy and homebrew, exploits made the PSP ground zero for multi-system emulation fans. The PSP display was significantly better and the system, prior to the 3DS, was significantly more powerful.
We're about to see the Vita assume the PSP's place on that mantle, it looks like.
