PSP Custom Firmware 3.80 M33 Released!+Update


Dark-AleX has released PSP Custom Firmware 3.80 M33. But he has also just released an update with the following bug fixes

  • Function scePowerGetClockFrequency / scePowerGetClockFrequencyInt was not resolved properly due to confusion between two nids applying to the same function. Fixed, this update is necessary for plugins and kernel homebrew reporting PSP CPU speed.
  • PSX EBOOT.PBP that have an icon of 80×80 pixels will not be replaced by Dracula icon in savedata.

In order for you to install this update you’ll need to have CFW 3.52 M33-3 Or higher.


  • Copy the UPDATE folder into /PSP/GAME/
  • Get the 3.80 Sony update, rename to 380.PBP, and put it in same folder.
  • Run it, the update will be done by Sony updater. At the end when you are asked to reboot the PSP pressing X or O.

3.80 M33 Changes:

  • HEN core: user mode can load now signchecked files from flash.
  • recovery: flash1 format will create flash1 directories after format. This could fix some flash1 issues with the previous versions.
  • Network update from page. By default is enabled. You can turn it off in recovery (when off, network update will download sony updates as usual).
  • Nids resolver for various kernel libraries.

Users should note:”popsloader plugin from 3.71 will not work in 3.80 M33 due to its system dependency. A new one will be rewritten for 3.80 M33.”

    I should point Out that the 3.80 m33 has many bugs even with the New Fix (3.80 m33-2) as it was pushed out to soon pluse note that it does not support popsloader Nore 1.50 Kernel SO. some of them fav. games you like to play or Apps you like so Much MAY NOT WORK on the 3.80 m33 For now i would stay on the 3.71 m33 till the 3.80 m33 gets to -3 or when ever the popsloader and 1.50 Kernel is FIX.
