steam-deck-tools VS rpcs3

I use Steam Deck tools for windows for all my deck buttons and shortcuts https://github.com/ayufan/steam-deck-tools

It's friendlier than it looks! First download the latest Steam Deck Tools release from GitHubsteam deck tools, then install RTSSrtss so the overlay and quick menus work, and optionally follow thisvrr guide to get VRR working. Make sure they're all set to run on startup and you should be good to go. The options all live in the task bar, and you can easily toggle between desktop/controller mode and different fan profiles, refresh rates, etc. It takes some fiddling around to get perfect but it has most, if not all, of the functionality of the native OS

Are you sure you are actually using Windows on the deck? Because except for getting the controller working in 3rd party launchers (which needs this single tool: https://github.com/ayufan/steam-deck-tools) - there were absolutely NO errors / hurdles at all. Everything just works as expected.

I prefer Steam Deck Tools for Windows https://github.com/ayufan/steam-deck-tools this is free, and adds pretty much full Stream Deck functionality to Windows. Steam Deck shortcuts for bringing up the windows keyboard, closing apps, alt tabbing, bringing up an overlay, using the overlay to choose frame rate and scaling options, etc, etc.

Steam Deck Tools I launch Diablo hold start and swaps to controller mode.

Install https://github.com/ayufan/steam-deck-tools This gives you control of fans, power limits, controller/mouse mode, etc. Its an all in 1 tool

And I use Steam Deck Tools for Windows for everything else and it works great https://github.com/ayufan/steam-deck-tools

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!
