We already have the first PlayStation 5 and PlayStation 4 game emulator for PC, KyTyyes, it is still in a very early stage of development, the version being available 0.1.0which is only compatible with the operating system Windows 10 in its 64-bit version.
that to its early phase, its creator indicates that it is already possible to run some other game commercial for PlayStation 4. Obviously, many of the games can experience graphical glitches, crashes, freezes, or run at low framerates to the point of being unplayable, so there is still plenty of development time left to iron out these issues.
This is related to the PlayStation 4, since with the PlayStation 5 things are even greener and still not able to run any game. Behind the emulator is InoriRuswho has already announced in the past the development of the Spine emulator and GPCS4 (PlayStation 4), so it seems that both projects have merged them into one and paved the way for the PlayStation 5. Knowing this, at least 35% of the 1,000+ PS4 games Tested in their day can be executed, but of course, now that they are fully playable, it is another story, and almost individual work is required, so it is to be expected that preference will be given to the most relevant titles.
If we take into account that the current and most popular PlayStation 3 emulator, the RPCS3was launched in May 2011 and to this day we are still actively working to try to make most games fully functional, you can imagine how long it will take for this to happen with PS4 and PS5 games.
