GBA Emulator for PSP

[MrMe]

Hi, I have a slim psp with cfw 5.00 m33-4. I recently felt nostalgic and wanted to play a few old gba games.

I downloaded gpSP 0.9 from: http://www.dcemu.co.uk/vbulletin/showthread.php?t=46046

And following exactly the instructions found here:

I also download a gba_bios.bin and put it inside the gpSP folder, yet it doesn't work!

When I tried to play gpSP it wouldn't started and this came out:
The game could not be started.
(8002014c)

Can anbody tell me what I'm missing?
Would appreciate it!

sure

you're missing 1.50 kernel, look for another version of gpSP that supports PSP slim.

I think this (http://dl.qj.net/uo-gpsp-kai-3.3-test-2-build-132-PSP-Emulators/pg/12/fid/25466/catid/122) one should work
