I use a Mister FPGA for emulation of pretty much all 5th gen and older consoles, as well as a ton of arcade games. I like to use it with my CRTs - it has direct analog video output, and it’s highly accurate hardware emulation with effectively zero latency by nature of it being FPGA. It was expensive but it turned out to be right at home in my CRT setup, and I couldn’t be happier with it.
