I've searched and could not find a solution.
I have 4.01 M33.
I tried both methods to install PS1 emulator listed in this thread:
(Ok so can't link, it's the thread called ULTIMATE Homebrew Guide / FAQ v2.20 (Updated Aug 14, 2008))
So since my 'GAME' folder is configured KERNEL 1.5, I try the "3) Installing Homebrew on a PSP with 1.5" method and gave me the same error.
Then there's another method for "4) Installing Homebrew on a PSP using Pre-made Eboot packs". Tried that - again same error.
I understand my CFW does not have PS1 already installed, so any help on what I'm doing wrong?
