My understanding is that it's nowhere near the state of, say, PSX emulators around the turn of the century. There's still swaths of late 2000s and 2010s releases that are unplayable without the original hardware.
RPCS3 has come a long way in the last few of years, both in performance and compatibility. Even Metal Gear Solid 4 is supposed to be playable (albeit using game patches) now. And emulating the PS3 architecture, with those weird Cell SPUs, has to be one of the most difficult emulations to implement.
I'm continually impressed by the emulation scene's passion for maintaining access to older games. LLMs/agents will be a force multiplier for that kind of skill and passion.
I guess I view 75% compatibility of the most oddball console architecture ever to be fairly successful. And it is still meaningfully gaining. It was 70% at the start of the year.
