1、使用方法解压缩文件，将UPDATE文件夹复制到记忆棒的PSP/GAME目录下（*如果您需要从3.71M33,3.80M33,3.90M33,4.01M33直接升级，还需要下载5.0M33文件包以及5.00官方固件）退回到XMB界面，在游戏里面找到升级程序，运行即可
3、英文原文----------Instructions: Copy UPDATE folder /PSP/GAME/ and run.If you come from a version prior to 5.00 M33, put sony update as 500.PBP in same folder, or let the program download it for you using a wifi connection.
