If you are really wanting to play circa 1993 games, your best bet would be to use a circa 1993 computer.
Emulation software can be good but it is not perfect and it may have been written more towards emulating for production software not games.
I think you will find that a lot of those games want to directly interact with the processor and memory and don't like what they are seeing. They may also be submitting requests to the CPU and receiving the information back much faster than they can process it.
I saw a lot of programs have that problem when the first (yes I said first) pentium chips came out. The chip would overrun the program.
