   For reference , Fex is a translation framework for x86 to ARM much like Apple’s Rosetta2 and Microsoft’s Prism.

   Valve sponsor development as it’s also the way the new Steam Frame supports x86 games. It’s also being used (as a fork) in Crossover Beta to replace the use of Rosetta2.

      Why doesnt Stream require their binaries to be compiled to some bytecode and transpiled during the install ?

      THen they wouldnt require any emulator for any new compiles.

         They do

         x86 bytecode is bytecode

            I mean don't modern CPUs basically just run an x86_64 emulator on a RISC machine anyway? Like there's a layer between the microcode and the actual x86 instructions already.

               Yes, but the “architecture-independent” bytecode for these RISC machines that run underneath your various Intel and AMD CPU models is the x86_64 instruction set.
