Mike at exophase is showcasing yet another Hello World running in the PSP emulator of the Vita.
Most likely this is not the same as Teck4′s exploit, but who knows, I remember a few months ago that several hackers found the sukkiri demo exploit exactly at the same time…
The developer behind this exploit wants to remain anonymous. So, to that John Doe, or to Mike, if you guys read this, by all means keep this one under wraps. There are definitely many game exploits on the PSP, probably more than we could wish for, but if you can spare this one for your own research, that’s great!
