If you look into the arcane architecture of the Playstation 3 console you quickly gain an appreciation for just how impressive the RPCS3 emulator is. PS3 is definitely one of hardest emulation targets, so it's wild they have the majority of the library working (with enhancements like upscaling and higher frame rates on many of the titles).

I guess it's nice people want to help and AI assisted coding can be fine but I can't imagine submitting a PR to a high-profile, much-revered project like that without reviewing and thoroughly testing it myself.

When I saw it treats SPE code in the same manner as shader code on GPUs that was an enlightening moment. It made so much sense to treat it like that. That move while complicated removes a lot of potential performance issues.
