you mean like the POPS emulator that the PSP used to run PlayStation 1 games (to correct the common mistake, the PSX was a completely different Japanese console, which only had the PlayStation as one of its parts).

PSX was a codename for the PlayStation. They decided to reuse the name for their failed entertainment center, but the name predates it by almost a decade.

I was unaware of that. I thought they were both PowerPC designs.
The only platform a PSX emulator might have not done full dynarec/interpretation would have been the PSP, and that's unlikely to actually exist for various reasons.
