One more, I point to this because it addresses quite a lot of stuff
that's needed to emulate a CPU, though you don't need to implement it
this way at all.

Generally these days, it doesn't pay to create a JIT, writing in C (or
even javascript in some instances) is enough of a portable "assembly"
language.
But yeah, do mind the endianness, integer sizes, etc.

Also Ferris Writes Emulators series is pretty good:

(He's got a few more emulator related playlists in his channel beyond
this one that are worth a watch.)
