I have the same problem with PSPUAE 0.63, it boots the splash screen, then just turns off the console. Also tested with 0.62 and 0.55a, same problems.
- kickstart is renamed kick13.rom and placed in KICKS
- __SCE__PSPUAE is placed in psp/game150/
I have fw 3.52 M33-4. PSPVice (C64 emulator) is just running fine, so I'm sure it runs homebrew stuff.
