I’m not particularly deep into the emulation scene or even a dev with actual knowledge. But from what i’ve read over the years X86 doesnt have to be a beneficial because the instruction set is ridiculously big and complex. While the chips are based off of PC hardware there still is a lot of custom fuckery going on which isnt publicly documented.

Prominent example is to look at the state of OG XBOX emulation vs PS2. Based on a Pentium 3 and some semi custom Nvidia GPU of that time and you would expect it to be perfectly emulateable. But even after almost 25 years xbox emulation is still in a rough spot. While PS2 emulation with its weird custom architecture thrives.

Widespread interest in a plattform is probably a far more important factor.

With that said PS4 emulation is already pretty mature considering how young the shad4 project is. Even though its also x86, but they’re using an approach more like WINE i think(!).

PS5 has almost no exclusives though. Like GT7, Astrobot aaand uh? I dont see put effort into it too soon.
