gpSP Help

Sorry if this has been asked a million times, but I couldn't find anything I was looking for with the search function.

I am trying to get gpSP v0.9 to work on my PSP. I have watched numerous YouTube videos, read multiple tutorials and triple checked my work, but every time I run gpSP my PSP comes up with the "game cannot start" message.

-I am running CFW 3.71 M33-3
-I have both the gpSP and gpSP% folders in the PSP\GAME150\ folder
-I have the GBA bios in the gpSP directory, named as "gba_bios.bin"

Is there anything I'm missing? Any help would be greatly appreciated.

Update:

I tried using gpSP Kai v3.2 Test 8 and it worked.

I sill cannot figure out why the gpSP v0.9 will not run, but if anyone knows please let me know.

Just wondering if you have the 1.5 kernal patch for the CFW

ye you cant play gpsp 1.5 eboot unless you have 1.5 kernel patch, but if you have a slim, you have to use 1.0 eboot on all homebrew
