Aura has updated his security application PSP Lock. It allows you to set a password before you actually can use your PSP.
Release notes:
I made this a while back, I’ve removed the annoyance of the Sony startup screen everytime you enter the XMB, and I’ve also fixed a few bugs in the code.
Tested on 3.52M33-4 but should work on all version.
Instructions are in the readme, and example lock.lock and config.lock files are also included.
Hopefully in a future update I’ll remove the 2 main bugs (CXMB and password upon exiting a game).
Any questions, just ask
