Suppose it really depends what emus you are talking about. Chankast won't run at any kind of decent speed on a 1.2. I tried it on my Morgan 1.1 when it was my primary CPU. Basicaly every game was quite far from playable.
SSE emulation
Im not sure where to put this so I will put this here I just want to ask is there a way to emulate SSE on a non SSE pc, cause i want to run chankast on my other machine but the procsser has not got SSE. plz can you help me.

Basicaly, I think what is really being said is 'not as far as we know', and even were it possible, it wouldn't be worth it.

Yes it is possible but it is an EXTREMELY bad idea to try and do so. The whole point of the SIMD (MMX, SSE, SSE2) is to have a single instruction process multiple data. To emulate the instructions on a processor which doesn't have them would involve trapping invalid opcode (INT 6) and emulating the instructions in a loop. This defeats the whole purpose of using the SIMD instructions in the first place. It's better to have different versions of critical performance routines (MMX/SSE/SSE2, MMX/SSE, MMX-only, non-SIMD)and use the appropriate routine for a given CPU after checking what's supported via CPUID level 1.
