Have you ever heard of MartyPC? I think you’d find it pretty interesting as well. It’s an IBM PC XT emulator that supports a bunch of essentially 8088-based systems, and it runs fully online.
They did a lot of benchmark testing with some really iconic demoscene productions, and the results are fascinating. Definitely give it a try if you haven’t already, the WebAssembly version is particularly impressive.

1 points · Open discussionThe most accurate IBM PC emulator is in rust.

In Memory-efficient enum arrays in ZigI don’t think Rust is inherently bad to write emulators. For example one of the best cycle-accurate IBM XT emulators is written in Rust: https://github.com/dbalsom/martypc
In Memory-efficient enum arrays in ZigI was a little confused why anyone would need or care for a cycle accurate 8088 emulator, but there's some answers on github. https://github.com/dbalsom/martypc

"8253 PIT - Recently rewritten after microcontroller-based research. At least one previously undocumented feature discovered. Accurate enough for PCM audio."
... and it turns out that it's this ...

// If the counting element was reloaded between load of LSB and MSB, it is an incomplete load.
// Reload the counting element again when we get the MSB.
// Note: This is completely undocumented behavior
