From what I've understood of this - it's transpiling the x86 code to ARM on the fly. I honestly would have thought it wasn't possible but hearing that they're doing it - it will be a monumental effort, but very feasible. The best part is that once they've gotten CRT and cdecl instructions working - actual application support won't be far behind. The biggest challenge will likely be inserting memory barriers correctly - a spinlock implemented in x86 assembly is highly unlikely to work correctly without a lot of effort to recognize and transpile that specific structure as a whole.

There is an open source project that already does this a bit called box86 and box64.

I think you can find videos of people running Skyrim on arm chips like phones or maybe raspberry pi 5.

They don’t run well, but with more powerful chips and valves experience and money, I’m sure they can do it.

But does it run Doom? Using CMOV instructions only?
