Make one easily using this software (you need an unzipper to use this (and you need Windows XP)):http://dl.qj.net/TOTALNewbi-easyInstaller-PSP-Tools-Utilities-(on-PC)/pg/12/fid/14749/catid/193Follow the instructions. Next you need a Pandora's Battery.Make one by opening it uphttp://youtube.com/watch?v=6iYPktUqPQkAnd following the steps.When you have a Pandora's Battery and a Magic Memory Stick, put in the magic memory stick, then the pandora's battery, then install 3.71 M33!
