Install 6.35 Hen + Prometheus ISO loader on your PSP

If your PSP is on 6.35 OFW, don’t fret, there’s still the 6.35 Hen available for your system and the Prometheus ISO loader that will allow you to play those free PSP games. Note that if you’re on 6.20 OFW, follow this 6.20 HEN guide instead or if you’re on 6.31, follow the 6.31 HEN.

Requirements for 6.35 Hen and Prometheus ISO

Installing 6.35 Hen and Prometheus ISO loader on your PSP

  • Extract the Mina no Sukkiri Demo onto your PC
  • Copy the folder (NPJG90047) into x:\PSP\GAME (x is your memory stick or the PSP Go‘s storage)
  • Extract the 6.35 file onto your PC
  • Copy it’s contents directly onto your PSP. This contains both the homebrew loader and the exploited save data.
  • Extract the Prometheus ISO loader onto your PC
  • Copy the extracted folder to x:\PSP\GAME (x is your memory stick or the PSP Go‘s storage)
  • Extract the Light VSH menu file for your PSP model on your computer.
  • Copy the plugins folder directly onto your memory stick or the storage of your PSP Go.
  • On your XMB, Run the Mina no Sukkiri
  • Select the second option to load the save exploit. This would automatically load Hen onto your PSP and it will revert back to XMB
  • Once you’re back on the XMB, press “select” to make sure the Hen menu displays correctly.
  • Follow this guide: Installing the Prometheus ISO loader on your PSP.
  • Enjoy your Free PSP Games :).

Update: Added installation of Light VSH Menu.  Why is it at the start of the installation process?  So you can immediately load it after installing the 6.31 Hen.

Important Note: Be sure to check the Prometheus ISO loader compatibility guide
Important Note: You need an ISO folder in your PSP’s memory. Simply create one and dump your PSP ISOs/CSOs there.
