Developer kgsws released " the first signed homebrew." It requires zero hacks and can run on any firmware and on any psp. Imagine you running homebrew on a psp without having to moddify it or hack it.

How to install:
Just make a directory in PSP/GAME and then place this eboot in it and run from the XMB! Nice, hopefully this will now lead to homebrew games and applications that can be run on all PSP’s hacked or not hacked.

kgsws answers:
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
– [sic]
Confirmed working on my PSPgo OFW 6.20. kgsws, everyone else involved — props, nice work!
