First "Signed" PSP Homebrew Example By Kgsws (NO CFW/HEN)
Developer kgsws shares an example homebrew that requires zero hacks — run it on any PSP — any PSP at all — no HEN or CFW needed. Just create a directory under PSP/GAME and copy this EBOOT.PBP there. Now run it from the XMB. How ya like that?
How’s it work?

Quote:Simple, notice it contains ~PSP header from demo game (UCES00206), it is exactly same header. It is easy to craft last 16 bytes of encrypted data block to match header CMAC – yes, that’s the trick
There are some strange thigs, it can’t run homebrews with bigger executable block (data block does not matter), and because of ~PSP header, it has to match exact size of original game.
This trick might be possible on firmware kernel modules to get permanent HEN on non-pandrorable PSPs, i was not able to do it but i was not trying that much.
PS: i am not only one who found this trick
