Tips On Increasing Emulator Framerate???

I have tries a few emulators but morphgear is by far the best, but seems like the GBA games no matter where i try i cant get a playable framerate, really slow.... SNES, NES, and GameBoy Color are practically perfect even with sound on but i cant seem to get similar results for GameBoy Advance.Is there any tips on increasing performance in frames or tweaks i can do to make my device faster from any fellow emulator users? Or is the Vogue chipset too weak??

I dont think its an issue of the chipset being strong enough or too weak, like many have stated and the reason TF3D hasn't been fully ported let alone the glitchy video playback in some apps/codecs is because of the drivers fully implementing the chipset has not, nor from the looks of it will ever be released

searching finds alot of dead ends in regards to implementing full D3D driver support although some close calls there seems to be that elusive spark to turn the chipset lead into true 3D gold
