Help with super smash bros melee running slow.

[MrDark]

I'm new to using dolphin (Ive used other emulators though) and cant seem to get a decent fps speed with super smash bros melee.

My specs are: (cpuz site link is broken thanks to weird internet stuff.)

Intel® Pentium® 4 CPU 3.20GHz
Windows XP professional 32 bit (version 5.1,build 2600) SP3
Direct X 9.0c
Memory: 1022MB RAM
Page file: 432MB used 2024 MB available.
Dell inc.
Dimension XPS Gen 4
BIOS: (doubt its necessary but...) Phoenix ROM BIOS PLUS version 1.10 A05

DISPLAY:

NVIDIA GeForce 6800
Aprox memory: 256.0MB

I used dxdiag for this.

I really just want to know what settings or something to do to make it go faster.
