  • Fixed custom CPU clock not working in games
  • CPU clock has never (in any SE/OE/M33) be set at all in games that restarted using sceKernelLoadExec to use a subgame or reload themselves, after said restart happened (e.g. Castlevania). Fixed.
  • Added setting to recovery to hide PIC0.PNG and PIC1.PNG in the XMB game menu By default off, when on you will probably notice a faster browse in XMB games. This setting only applies to any kind of apps/games (pbp, iso) that load from MS, but not to UMD's.

  • Added some internal changes required by incoming 3.80 popsloader plugin.
DownloadVersion 3.80.2
  • Function scePowerGetClockFrequency/scePowerGetClockFrequencyInt was not resolved properly due to a confusion between the two nids applying to the same function. Fixed, this update is necessary for plugins and kernel homebrew reporting psp cpu speed.

    • Fixed a bug that could hang the psp when exiting with home.
    • Fixed compatibility issue with Castlevania Dracula X Chronicles, and maybe more games.
  • Vshmenu: it wasn't displaying properly with psp slim TV-OUT due to the change of resolution. Fixed.
DownloadVersion 3.71.2
  • There was a bug that caused corruption when writing files of more than 32256 bytes using usb flash. The bug has been corrected, and now the implementation is as reliable as it was when it was based on 1.50 kernel. (tested with a full restauration of a dump)
  • Psp Slim: a functionality to let the charge of battery when connecting a usb cable has been added. This feature is based on Noobz plugin code. By default is not enabled, you can enable it in recovery. Note that the charge of battery may be delayed some seconds since the moment you plug the cable.
  • After installing this update, program at PSP/GAME/UPDATE will always be executed on 3.71 kernel, despite configuration.
  • VSHMenu: vshmenu will not be executed when onscreen keyboard is active, to avoid the lost of the select button function in the keyboard. An option to reset the psp has been added.
  • VSH plugins are not longer executed anymore in recovery mode, that was the cause of pseudo-bricks.
