In this video I will measure the input latency of different Spectrum emulators, an FPGA, and a real Spectrum (time elapsed between a key is pressed, to the image change, or sound is heard). I make a comparison in which the FPGA SiDi comes ahead of the others, with a very honorable second place for ZXBaremulator emulator for Raspberry Pi. I have tried to do all the measurements following the same criteria in the most honest way possible. However, since it is an approximate method, I cannot guarantee that my measurements will match other people's with the same or other methods. Test program: https://github.com/dcrespo3d/ZX-Input... FUSE emulator: http://fuse-emulator.sourceforge.net/ RetroVirtualMachine Emulator: http://www.retrovirtualmachine.org/ ZEsarUX Emulator: https://github.com/chernandezba/zesar...
