Only Uncharted 4 is available on PC, none of the PS3 era games are available, sadly. I haven’t tried on the most recent version of the emulator, but:

Uncharted 1: I’ve completed, it’s basically flawless Uncharted 2: I got right to the final level, but the demon hallucination things crash the game Uncharted 3: I’ve completed, but it crashed a LOT, and there are several janky spots with crazy slow downs etc. like the ship graveyard. It’s also a bit annoying to get running in the first place. The recommended settings are actually required in my experience. Doesn’t work without them.

I love me some Uncharted! Emulator is going to be the best way to play them soon. It’s already superior imo because I was able to set up gyro aim
