Kingdom Hearts: Birth by Sleep - US - ULUS10505

[Red Joker]

Now, my only problem is the speed.I think in the PSP, the FPS in Battle Mode is around 30. Here, it's around 8 FPS, which is annoying because I can't get past the shotlock tutorial.
My specs are :
1 GB RAM
Intel Dual Core @1.6GHz
Mobile Intel 965 Express Chipset Family (My Graphic Card)

Settings (The checked ones ):
Video : All unchecked
Memory : Ignore invalid memory address
Media : Use Media Engine and SonicStage
Compiler : Use Compiler (dynarec) and the max method is 50.
Display : Anti-Aliasing off and Res. is native
I'm grateful to anyone who can help me . Help, I'm a newbie.
