It's only a matter of time until most of these games get vibe-coded back end clones. Still not as good as a full ROM but at least and improvement over complete unplayability.
Even if they were pixel perfect clones with exactly the same play. As a person who vibe codes like there's no tomorrow to have custom software, I still find the color of the bytes important for something like a retrogame.
Otherwise it's like color photocopy of an art piece.
PS4 is AMD64 based. And so few games leveraged the cell processor in the PS3 to it's fullest, IIRC, the current emulation strategy is to translate the cell calls to x86. So the hard work is actually already done.
