Using the original firmware, you can run a signed copy of HEN straight from the XMB without having to run any "Minna no Sukkiri (demo)" exploits.
To do that, you'll need:
- PSP original firmware v6.35
- A way to access the memory stick.
- A signed version of HEN (I'm using liquidzigong's 6.35 PRO)
- The rest of the instructions for setting it up are the same as homebrew for 6.31 except you do not need to do anything related to "Minna no Sukkiri" demo/save data.
- Move your current HEN files ("ms:\h.bin" and "ms:\hbl") to a backup folder (in case anything goes pear shaped).
- Extract EBOOT.PBP from the HEN archive into "ms:\PSP\GAME\635PROHEN"
- That is all.
- From the memory card, select "635 HEN by Coldbird & VF".
- This will reboot your PSP as usual and then bring you back to the main menu.
- Then select your homebrew (ie. Prometheus ISO loader) and enjoy!
- This is living.
