Performance might be better, but compatibility is likely to be worse. In that regard, I'm worried that emulation-based compatibility is much more likely to be an ad-hoc crowd-sourced thing-- how many titles work fine for the first 1-5-10-15 hours, then you hit that one time it uses an unsupported API call? If I rely on some crowd-sourced database that says "platinum compatibility", what's my recourse then? I guess I'm picturing my experience with FF7 on Windows back in the early 2000s, where it played fine until the middle of the 2nd or 3rd disc and then had a showstopping crash; soured my experience on it for years until I got the late-2010s rerelease which could make it to completion.
