Quickest Exit is a very simple plugin to activate in GAME. Its function is to replace the classical HOME meni (the meni that appear when you presses HOME during a game or homebrew) and to enable the quick exit from the game or homebrew. So, if you enable the plugin, when you will press the HOME button during a game or homebrew, PSP will return to dashboard immediately, with a great time profit.
