This is the New XMB control for PSP running on ME, PRO and GOD Custom Firmwares (CFW)'s. This basically puts the Recovery menu on the XMB for you.
After Downloading the File from the link below, Extract the files and you will see the xmbcntrl folder. Take that folder and place it in the ms0:/PSP/GAME folder or on PSP Go ef0:/PSP/GAME folder and exit USB mode and run it from the XMB. If your running CFW ME use the ME installation, If your using PRO or GOD CFW use the PRO install. Reason using this for GOD is because GOD is based off of PRO CFW and its more compatible. Once you've done that you should be ok and PRO Settings should show right above System settings on the XMB.
If you DO NOT see the PRO Settings, don't panic. Go back into USB mode and go to your seplugins folder and open the VSH text. If you have a PSP Go you need to change it to read ef0:/ at the beginning instead of ms0:/ at the beginning cause its probably on the HDD instead of the Memory Stick (MS) especially if you don't have a MS.
