Whats the smallest amount of time to completely emulate a Spectrum?
Maybe the ULAs timings as mentioned here: https://opencores.org/projects/zx_ula?
If we go for a "Single step Emulation" and want to get a proper display whats on the screen, we may need to have two screens: One which displays "whats on screen" at this step. And another one which is calculated from this step "50 or 60Hz further" to show effects which are created by the full speed running Spectrum.
