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
2、更新内容-使用了scePower_EBD177D6 代替了scePowerSetClockFrequency来改变速度 从而解决了在某些游戏运行时没有正确锁定速度的问题(简言之改变cpu时 速度锁定更精确 一切尽在掌握)- UMD/ISO 速度选择也被应用到了psn游戏当中-libupdown.prx 被连接到了dark-alex.org 上面而不是sony网站 当 npsignin_plugin 检查新版本和m33升级功能被启用(应该是直接升级m33固件而不是升级官方固件的意思吧)-Iso文件的描述符号没有在驱动删除时被关闭-在VSH menu中加入了关机功能-修复psp未插记忆棒,或插入损坏记忆棒无法进入恢复模式的BUG-M33网络升级不会出现DNS错误之类的报告了-优化了记忆棒读取速度，试着让CSO的读取速度接近于ISO
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.
4、Changes:- Speed sele罕铞泱殳cted for umd/iso was not properl烤恤鹇灭y locked in some new games that used scePower_EBD177D6 instead of scePowerSetClockFrequency to change speed.- UMD/ISO speed settings now apply to PSN games too.- Fixed libupdown.prx connecting to dark-alex.org instead of sony when npsignin_plugin checks for a new version and m33 update is enabled.- Iso file descriptor was not closed in driver deletion- Added a shutdown command to vshmenu.
