I am curious about how the inner workings of the emulator work. Is it mostly assembly? Can we get some boosts from SIMD operations from SSE/SSE2/3dNow/MMX/Altivec? I bet there are some huge opportunities for optimization considering a N64 emulator runs faster than DOS games right now!!! 😜

How important is FPU speed for the emulator? Old games were mainly integer based for the poor 486. It wasn't until Quake when John Carmack discovered the fun of the dual issue Pentium FPU that floating point really came into the picture....

Dark Forces is noticably slower on a computer without a FPU, or if the FPU is simply turned off in the BIOS.
