Power Management Plugin PSP

Power Management Plugin is a tool designed to optimize your PSP's energy consumption while you stay on the XMB. Coded in C/C++.

Installation

Copy the content from the binaries folder to ms0:/seplugins/.

If you have a VSH.TXT copy the line of the file bundled with this pack and append it to your own VSH.TXT file.

Open the recovery and activate the plugin.

This plugin has 4 main functions.

Music Mode (L+R):

This mode perform an underclock to 60Mhz for the CPU and 30 Mhz for the main system bus.
Suitable to listen to your Mp3 and even ATRAC music files.
Press L+R once again will set the CPU speeds to the ones you had previously configured.

ToggleIdle (R+Start):

This mode disables the autoidle feature of the console (not of the screen), useful when watching pictures of any kind.

PowerLock (R+Note):

This mode will block the console power switch in order to prevent an accidental turn off of the system.
If you toggled it on and you attempted to turn off the console it will simply don't.
But when you unlock it, the console automatically will turn off (if you did not touch the power switch it will unlock but it won't turn off the system).

Black Screen Mode (L+Start):

This will turn off the PSP Screen until you press L+Start again, the screen will turn on and set itself with the previous brightness level you had.
Useful to use together with Music Mode it can save you a lot of battery.

Software full power off (R+Square):

L+R - Music Mode

R+Start - ToggleIdle

R+Note - PowerLock

L+Start - Black Screen Mode

R+Square - Power off

The latest build has been configured for the 3.9x Firmware series, with legacy compatibility for 3.7x and 3.8x not fully supported.

0.2.3 version

The plugin has been fixed to work as intended with the 3.9X firmware series, legacy compatibility with 3.7X or 3.8X is not assured nor supported.
Dependence of kernel libraries has been reduced, increasing compatibility with further firmwares.
Source code has been tidied to avoid stub dependences and functions called directly from libraries (extern-defined functions) where possible.
Built against the latest PSPSDK.

0.2.2 Version

Ported to 3.71 Kernel, for use with previous firmwares, use 0.21 Release.
To turn off the PSP use R+SQUARE, it was changed in order to avoid conflicts with M33 Firmware VSHMenu.

0.2.1 Version

On Screen notifications when you activate a mode are displayed, these ones are a bit experimental, so their behaviour may not be the adequate under some situations.
The Software Full Power Off has been modified, it now turns off completely the system without risk of crash. If PowerLock is active, the Software Power Off will be locked too.
The plugin seems to work in all the places of the XMB but is recommendable to turn modes in the XMB root to avoid conflicts with button press combos, crashes seem to have been bypassed.

0.2 Version

Added the Black Screen Mode, it turns off your PSP Screen, and if you press buttons it will remain black, useful when listening songs
Fixed the compatibility bugs which lead te system to a crash with the latest M33 Firmaware updates
Some of the key combinations were changed in order to be more compatible with the latest M33 updates, and by popular demand with Wildcard Firmwares too
