Cita:Japanese PSP scener Mamosuke announced today on his blog that he was able to confirm a ÔÇ£Hello WorldÔÇØ running on the PS Vita through the embedded PSP emulator. The exploit was made by developer teck4, and most likely relies on one of our good buffer overflow friends. and for those who are wondering ÔÇ£is it real?ÔÇØ, my current answer is that I havenÔÇÖt tried it yet, but knowing Mamosuke fairly well I can tell you itÔÇÖs true.
Technically, the idea behind the hack is simple but brilliant: the PS Vita has a PSP emulator, and we have plenty of PSP game exploits lying around can we assume they will work on the emulator? Thats what teck4 tried, and the answer is yes, so he managed to run unsigned code on the PS Vita.
...
ThatÔÇÖs the theory. Practically, although this is good news, there are a bunch of obstacles which will probably not make the exploit so interesting for most users (at least not yet): First of all, the exploit happens within the PSP emulator on the Vita, and will not directly give access to the Vita hardware or features. So this can theoretically only allow to run PSP homebrews on the vita (which, to me, is already fairly nice), and also, only User-mode ones ( a game exploit does not give access to the PSP kernel mode, so some tools and functionality is missing, which prevents emulators such as Daedalusx64 for example to run at full speed).

Básicamente lo que han conseguido es entrar al emulador de PSP que lleva incorporado la Vita, y a partir de ahí podrán correr toda la scene de PSP. Hasta el momento, el hardware y el software de los juegos de Vita está intacto.
