SDE ssse2 emulation

Hi all, hope you can help me out.

I was wondering if it is possible to just emulate ssse2 using the SDE and if so how would this be accomplished?

I have tried using the --help but all them option confuse the hell outta me.

Thank you in advance for any help you can offer me.

There is no SSSE2 extension. There are SSE2 (https://en.wikipedia.org/wiki/SSE2) and SSSE3 (https://en.wikipedia.org/wiki/SSSE3) extensions. Depending on which one you want to emulate you have to use one of the SDE command line options that correspond to the CPU architecture that introduced that ISA extension. For SSE2 that would be Pentium 4 (the option is -p4) and for SSSE3 that would be Merom (-mrm).

Note that both SSE2 and SSSE3 are available in hardware for a very long time now, so most likely by running SDE you won't be emulating them but actually disabling any more advanced extensions that might be supported by your CPU.
