If there was a way to take advantageof the 2nd core I believe emulation would reach very desirable speeds that's 666mhz all together and project 64 recommendations are 700mhz 666mhz would be fast enough. I cant find the speed of the Voodoo2/Banshee Based 3DFX Card but im sure it's extremely slow and it's so old I think the psp's gpu may be more powerful cus because the cpu is more powerful.
