Proton experimental & proton-ge doesnt work with the game wine staging 9.21 does tho
WINE_CPU_TOPOLOGY=2:0,1 %command%
On higher core count CPUs, the game will eventually fail to load assets and crash after a few hours of gameplay. Using Proton 9 and its environment variable WINE_CPU_TOPOLOGY=2:0,1
to limit the game to 2 CPUs seems to fix it.

Runs great by default

FPS lock -> 30 fps / Half Rate shading = enabled / TDP limit -> 3w / GPU clock -> 300 MHz
Played the game from start to finish without issues. Sometimes the resolution when starting the game is wrong but as soon as you enter the main menu it fixes itself. The tweaks for battery allow the LCD deck model to have about 7hs of battery while playing, without any loss in visual quality or compromising gameplay experience.
Game works perfectly

Gamw runs flawlessly without being a big battery drain

Sometimes the game would not boot on start up. All I did to remedy this was close the game and start it up again. This always worked.

Works completely as expected out of the box.
Not much to say here, as this one doesn't require a whole lot to run. There's not a whole lot of graphical options either. If you want to cap the framerate, use DXVK_FRAME_RATE
, the mangohud
frame limiter, libstrangle
, or the gamescope
frame limiter. The choice is yours, all of those seemed to work just fine.

The disappearing sprites & crash is annoying, but infrequent enough to not ruin the game for me.
gamescope -H 1440 -h 1440 -W 2560 -w 2560 --adaptive-sync -e %command%
Occasionally character sprites disappear, seems to happen after playing for some time (>1h)
Fullscreen only works with gamescope
After a character sprite dissappears, opening the menu causes a crash. Has never crashed under other circumstances.

PROTON_USE_WINED3D=1 %command%
Sometimes the music crackles, though it doesn't always happen and I don't consider it a deal breaker
Because my IGPU (Intel Iris 5100-Haswell) has incomplete vulkan support, I had to lauch with "PROTON_USE_WINED3D=1 %command%", but overall I had a blast playing this game on linux.

Set watt to 5w. (For 60fps!)

gamemoderun %command%
using Proton Experimental. enabled vsync on game settings. game screen does not shake when panning the scene.

Dropped TDP to 3 W, limited frames to 30 fps.
Faint crackling very infrequently.
This isn't a demanding game so make sure to optimize for battery life.

Game works perfectly when framerate is capped at 60. Touchpad controls are a plus; just like the DS days.
Change right trackpad to move Mouse, and "Touch" command to left click (this lets me "examine" areas easier). Changed back grip buttons to "A button" (Confirm/Examine) and "Y Button" (Present Evidence).
TDP and GPU Clock can be lowered quite a bit without slowdown. I use the lowest settings.
The game can be blurry on first start up due to low default resolution. Set the resolution in the game's settings.
Sometimes audio can become horribly distorted after waking from sleep. Saving and restarting the game always fixed this.
Game can be choppy when "panning" (courtroom scenes, examining 2-screen rooms). Cap framerate to make this less noticeable.
Also, disabling ingame V-Sync and keeping Steam's V-Sync on ("Allow Tearing" off) may help with latency and smoothness.

gamescope -h1440 -H1440 -b -r144 --framerate-limit 144 -- %command%
When not using Gamescope, game would sometimes silently fail. When this would happen, character portraits would disappear and opening the Options menu whould close the game. Running in Gamescope with fixed refresh/framerate fixed the issue.
During one session, the game didn't act when the lower half of the screen was clicked. Restarting the game fixed it.
Slight choppiness when screen is "panning" (courtroom scenes, 2-screen investigation rooms). Fixed (or at least less noticeable) by capping framerate to refresh rate using Gamescope.

Works well with very little issues.
when playing on my laptop on the side, it was a little demanding to run.
I've had one or two crashes. They are very rare.
There was a moment where the characters stopped speaking after reloading a save and the game softlocked.

Game runs perfectly, finished it on the Steam deck. The few times it shows keyboard icons or starts at a weird resolution do not affect the gameplay at all.

One of those instances will happen depending on the renderer used in Proton:
On DXVK (default), sprites will be missing and fix itself. Happens when playing for too long. Once you experience that, expect the game to crash once you try to go to Options or reach the checkpoint for saving the game.
With WineD3D, major graphical artifacts will appear and break the game entirely.
It is possible that it may happen when switching between windows (With Alt+TAB) too much in full screen.
The best way to play this game is to use Gamescope to avoid any issues, despite not owning the Steam Deck I think it will run just fine on it.

Minor hickups while the camera is sliding left and right during trials

flawless experience with Xbox One Controller
works flawless
Runs perfectly, no problems here!

The game may launch with wrong resolution, but resolution is right in main menu and story.

Game sometimes starts with a weird resolution, but fixes itself once you get to the main menu.

Set TDP limit to 4w, but it's not necessary. I got 5+ hours of battery.
The game runs out of the box.
Works, but wished this was a better port job.
This is a hold over from Windows, but the full screen takes a bit to load and it's hard to tell if it's working until the game start/restarts. I blame Capcom and Windows for this, not Proton/wine
Any issues you find here are going to be the same on Linux as it is on Windows. Probably going back to the 3DS or CITRA to play these games.

made right trackpad press Left Mouse Click instead of being right stick click
3W TDP
Keyboard prompts show up sometimes instead of controller prompts, but it's only if you accidentally touch the screen or use the mouse.

Sometimes displays keyboard prompts instead of or alongside gamepad prompts.

Perfect!
Plays like native, encountered no issues.

There's a minor visual hiccup, but only on first startup. Keyboard prompts are sometimes displayed in menus, but it plays flawlessly.
The game briefly displays at the wrong resolution upon first startup, but the problem fixes itself by the time you reach the title screen. There are keyboard prompts present during menus, but they don't show up during actual gameplay.
Running in 40Hz mode seems ok
Opens up at a weird resolution but resolves itself
Has non-gamepad controller glyphs throughout
Works great out of the box. No tinkering required.
if you want to install the spanish community patch... you NEED access to windows, there is no way around that sadly
i had one crash, but i think it was due to the translation patch i'm using, not sure
