rpcs3 VS citra

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!

Doesn't cover 3DS (Citra)

Another wonderful option is to play Nintendo 3DS games with the Citra emulator. They look incredible. I would go so far as to say that if you're a fan of the console then this is the best way to experience its games, even better than on the original hardware. Again use 3840x1200 @ 60 Hz and full SBS. In Emulation -> Configure... -> Graphics -> Stereoscopy set it to "Side by Side". Also increase the renderer internal resolution to as high as your PC can handle (I used "5x Native"). We'll also have to set the display layout for our resolution and aspect ratio. Unfortunately, this has to be done manually. Browse to %APPDATA%\Citra\config and edit qt-config.ini with this in the [display] section:

After some more research, I discovered that the Citra devs discovered and fixed this issue by allowing the Back button to open the in-emulation menu. This fix was added on Jan 22 2023. When I checked the version of Citra available on the Google Play Store on my phone, it was a very old version from May 2021, which is strange because viewing the same Play Store page on my computer shows it was updated in April 2023... maybe your Play Store version is also outdated? If so, the only solution I can think of would be to install the apk from the Citra Nightly github repo.

You might want to consider compiling it on your Mac yourself, rather than trying to download a build, given the situation with MacOS transitioning to ARM. Beyond that, your question is related ton emulation, not ROMs specifically, so if you still need help, ask on related subreddits like r/EmulationOnMacOS and r/CitraEmulator.

https://citra-emu.org/ just typing the console + emulator on any search engine should give u the best option most of the time

I used the one here (you need a github account): https://github.com/citra-emu/citra/actions/runs/5078058438

There have been several recent changes merged for custom textures. Here is one of the pull requests for example: https://github.com/citra-emu/citra/pull/6452. The slow loading you're talking about was only an issue for me if preload custom textures was enabled.
