fpPS4 VS rpcs3

PlayStation 4: fpPS4 is the best PS4 Emulator according to the emulation wiki (PS4 Emulation is very early in development so it's not recommended you use PS4 emulation): Download fpPS4

Yes, in fact the PS4 is beginning to see HLE with various emulators, most notably fpPS4 (free pascal PS4).

There's a couple actually. Spine was the most impressive at the time of its last release, but it's been about a year since that release and whether it's still being developed is still unknown. fpPS4 and Obliteration seems to be the most promising right now.

PS4 emulation is in the works, but playing something like Ghosts of Tsushima is years away. fpPS4 and Obliteration are experimental emulators / compatibility layers, but they’ve only been in development for a few years and can just boot simple games. That being said, Ghost of Tsushima was one of many games listed in the GeForce NOW leak from Ighor July a few years ago; Since then, many of the games listed have indeed been announced for PC, so a PC port might be on its way.

There's a PS4 emulator being developed in Pascal. For real.

The emulator: https://rpcs3.net/ The rom: https://vimm.net/vault/24833 I forget if you need anything else but finding a video on YouTube is not very hard for rpcs3, a bit complicated, sorry I can't remember how to do it all, it's been a while.

What you'll need: A PC with a decent CPU (RPCS3 tierlist of CPUs), a legally obtained copy of Sly Cooper: Thieves in Time (eBay link for physical; getting your own digital copies of PS3 games is a bit more complex and requires jailbreaking your PS3, I recommend MrMario2011's channel for any PS3 jailbreaking you need to do... or Google), and a PS3 emulator for PC (RPCS3 is the only one you should look at). Note that you can also run RPCS3 on Linux and macOS but I have no experience with that so any system requirements will have to be found by you). You also need a DualShock 4 (PlayStation Store link), a DualSense (PlayStation Store link), or another controller that has gyro functionality. There are other methods for bypassing gyro, such as emulating gyro (GitHub link for DualShock 4 emulator) or modifying your saves to skip past mandatory gyro sections of the game (PasteBin link for a tutorial). Also check out the RPCS3 wiki page for the game for any potential fixes.

RPCS3 (PlayStation 3) Emulator: https://rpcs3.net/

it's the same issue as here: https://github.com/RPCS3/rpcs3/issues/13031

Finally, there is a sizeable catalog of PlayStation 3 games that support 3D, which you can output in SBS using the RPCS3 emulator. Their resolution is quite low but the stereo effect can still be impressive. Note that normally only half SBS is supported, but some games might have a community patch for widescreen resolutions, in which case full SBS might be possible. Make sure to set Configuration -> GPU -> 3D to "Side-by-side" before starting a game. This will tell the game that you are connected to a 3D display, in which case it would have an in-game option to enable stereoscopic 3D. You might also need to set the aspect ratio to 4:3. I can confirm that Prince of Persia Trilogy 3D works nicely. Note that you need a fairly beefy gaming rig to emulate PlayStation 3 well!
