Guide to Devhook

The Introduction to Devhook

Devhook is a application for the PSP that allows the user to emulate firmware up to 3.11 This application will allow users to have the newest features of the homebrew locked firmwares and the ability to run new games, without having to flash a different firmware to the PSP.
