Custom Firmware 3.40 oe-a quistion/Help

Hey, I recently bought a PSP and have 3.40 oe-a custom firmware. The problem is that when I go to install homebrew games or emulators I keep getting errors.

I have gotten Daedalus to work but when I try to play anything else like gpsp.9 I get the error code 80020141.

any help would be appreciated :o

Put the emulator and homebrews wich requires 1.5 kernel in GAME150, not in GAME folder.

what sarrachini said and if that doesnt work go into recovery, enable 3.40 kernel and make a folder called GAME340 put em in that
