GBA4iOS VS rpcs3

Not surprising at all; the App's screenshots bared more than a passing resemblance to GBA4iOS: https://github.com/CocoaBob/GBA4iOS

Really just makes you think how much easier things would be if you could simply distribute Open Source apps safely on iOS. This one-two step of ad-ridden forks and who-knows-what isn't making things any easier for users. Nobody wants good software to be polluted with anti-features and redistributed by someone that isn't the maintainer.

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!
