更新内容：
- Speed selected for umd/iso was not properly 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
-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
- Added a shutdown command to vshmenu.
