Power Management Plugin changelog

If you're one of those people who tend to run their PlayStation Portable's battery ragged on a regular basis, you might find developer 3r Ch4mp1's Power Management Plugin for your handheld rather useful.

For those of you not familiar with this program, this plugin is designed to optimize your PSP's energy consumption while you stay on the XMB. The latest build has been configured for the 3.9x firmware series, with legacy compatibility for 3.7x and 3.8x not fully supported.

Here are the details of the new changes since our previous coverage of Power Management Plugin:

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

-Dependance of kernel libraries has been reduced, increasing compatibility with
further firmwares.

-Source code has been tidied to avoid stub dependances and functions called directlty
from libraries (extern-defined functions) where possible.

-Built against the latest PSPSDK

As always, don't forget to read up on the plugin's documentation for instructions on how to properly install it into your handheld. You can also find additional information on the program's different features there.

Homebrew developer 3r Ch4mp1 returns with an update to his Power Management Plugin. From the previous version, this release now clocks the app to v0.22. It's a rather short changelog, but the new features are pretty important too. Some of you guys might have been waiting for these to be incorporated. Especially the 3.71 upgrade.

Power Management Plugin v0.22 has the following changelog:

• 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

3r Ch4mp1 is back with yet another update on the simple and yet highly useful Power Management Plugin. As the name of the homebrew implies, this little tool allows you to toggle and configure settings to maximize your PSP battery's juices - conserve its energy and save on some game time.

Changes for Power Management Plugin v0.21 include:

• On Screen notifications when you activate a mode are displayed, thes 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.

If it's your first time to use this tool, the readme is included in the download. Make sure you look at it thoroughly. As before, 3r Ch4mp1 is giving a shout out of thanks to Neophyte, CoolJ, pspdev.org, his friends, Noe and Rebeca, and above all, Mariloli (a special dedication from 3r Ch4mp1: "because I simply love you and i'm very happy of your return from holidays").

This plugin has been designed and coded to optimize the energy consumption of
the PSP while we stay in the XMB.

This plugin has 4 main functions described here.

-Music Mode: To activate this mode you have to press L+R, this performs 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. Pressing again L+R will set the CPU/Bus speeds to the ones you had previously configured.

-ToggleIdle: This mode disables the autoidle feature of the console (not of the screen) this mode can be toggled on/off by pressing R+START, useful when watching pictures of any kind (even porn! xD).

-PowerLock: Pressing R+NOTE you 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: Pressing L+START we turn off the PSP Screen until we press L+START again, the screen will turn on and set itself with the previous brightness level we had. Useful used toghether with Music Mode it can save you a lot of battery!

-Software full power off: Pressing R+SELECT, the system will turn off totally, this feature was too easy to implement, I lef this here because you liked it, and if it is useful to someone I won't remove it.

To prevent issues like console hang ups, execute all the modes in the root of the XMB.

Suggestions, bug reports and new features to implement are welcome, leave me them in this post or better in my devblog at

Test30 in his fastpower plugin, and this is what i've done in 4-5 Hours...
