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.

Although it can be more hassle to set up than custom firmware, the risks of bricking are lower, it's very easy to undo, and you can have multiple firmware versions installed at once, allowing you to choose the one you want for any given task.
