C# is a common choice for emulators, actually. It probably goes C/C++ (it's really hard to disambiguate the two, in this case; few codebases are pure either way) then Rust (for hobby emulators, it's probably third or fourth for serious efforts), C# and Java. JavaScript and Python are very common for hobby efforts, but generally exceptions for serious codebases (excepting WASM).
