I saw this a few days ago but have only just got round to posting it.
Quick Info
5h4d0w's Seplugins Manager v1.2b1 is a plugin manager which allows for users to edit, enable and disable plugins from the psp.
Developers Notes
Tested on 5.00 M33, 5.03 GEN, 5.50 GEN, 6.20 TN and 6.35 PRO (the latter two don't have recovery menus).
You can enable and disable plugins without a computer.
Works on PSP GOs, and can force loading from "ms0:/" instead of "ef0:/" (the internal storage).
Includes a built-in configuration editor. The editor is password-protected. The password will be encrypted.
Any changes to the config will be saved in "flash3:/" for extra security.
Note: The config is saved separately from the plugin .txt files (Pressing start in the config editor will not save plugins, and vice-versa).
Can add, edit, remove, toggle, and move plugins in all three .txt files.
(When adding a plugin, do NOT add the device name (ef0:/ or ms0:/) OR the 1/0 switch; It will add them for you.)
Only loads from .txt files that exist. If they don't exist, it creates them for you.
You can revert your changes by pressing [SELECT].
Gives the option to auto-exit from the app once you save your changes.
Allows you to decide which options are available (by editing the config).
(Example: You give a friend your PSP for a while but don't want him messing with your plugins, so you disable what you don't want him to do.)
Nice pop-up menu.
Can be "themed" (by editing the config; unfinished).
Will strip-out any empty lines in your text files, making them look cleaner.
Installation Instructions
Simply copy the folder SePlugins_Manager found in the attached folder, and paste it into the game folder found on the memory stick, in the folder psp.
Source
Includes screenshots, changelog and future ideas etc...
I'm still using scepRecovery for 620 TN. Although I do like the extra additions, and the developer is also thinking of adding in the ability to transfer plugins from one PSP to another (adhoc). Then I would most likely use this instead of scepRecovery, to save me from having to go to a computer to add plugins on my friends psp's.
