Game showed black screen on latest Proton build. Switched to Experimental and game played normally without issue.


Won't run with default proton at all, just shows black screen. Run flawlessly with Proton Experimental.

Changed settins via Controller Layout
Settings I used to get the game to work:
Click on game and hit properties, launch the controller layout (which is actually the video settings)\
Resolution: 1200x800
Screen Mode: Windowed Mode
Video Quality: High
Framerate Limit: 60 FPS
Vsync: Off
Controls: Default\
Hit Apply.
Now youi should be able to boot up the game fine.
Note: May need to decrease resolution to maintain 60FPS.
Set game resolution to 1080P in game properties
Game has a hard time reaching 60FPS on 1080P on medium settings, use 720P if you want constant 60 without sacrificing much else.
Out of the box, the game would only launch in desktop mode while game mode just gave me a white screen. What worked for me was going to Game Properties -> General -> Game resolution and setting it to 1080P, while also ticking the option for "internal and external display" for consistency across docked and undocked. Has to be 1080P, other resolutions or "Native" won't work.
Initially I also set the game to windowed but later realized using any of the 3 display modes works just fine as long as 1080P is being forced on the Steam settings. This could have been a "need to do it first time only" situation in which case I can't replicate it anymore, but should the forced 1080P not be enough for your situation, try launching the controller layout tool (which despite the name houses the video settings) and change from the default full screen to either windowed mode.
In game, running at 1080P on default settings (medium) would make the game chug along around the 40FPS range and rev up the fans, I changed to 720P and got stable 60FPS without the fan noise. Do note that changing the resolution requires you to use full screen or normal windowed, borderless gets locked to 1080P.
These settings worked fine for me on both docked and undocked mode. You can use 800P on undocked but I couldn't find any combination that got rid of the blackbars at the bottom so at the end I set it to 720P for consistency between modes.

Despite Steam Deck Verified status, it freezes at a white screen at startup. Using a brand new Steam Deck OLED with all OS defaults.
Tried various grahics options in launcher
Without some advanced potential workaround, it seems completely unplayable for now. It should be marked as unsupported on Steam Deck for now.

In general, set game resolution to 1080p and tick set resolution for internal and external display in the controller config, select vsync off and 30fps limit, and set resolution to 720p from there the game should run great.
need to tinker with the controller config for the game to run
if vsync is on then cutscene audio will be out of sync

GE-Proton-8-25 booted the game without any issue. Using the system default proton, 7.06, hotfix and experimental all gave a white screen on boot.
From past user reports, I initially set vsync off from the games's controller config tool at launch. I don't know if the vsync setting really made a difference as I was still able to boot perfectly fine after re-enabling vsync. I also cleared all compat data and could still boot the game with vsync on and GE-Proton set.

Since upgrading to an OLED deck this game no longer functions and just gets stuck on the white screen issue.
Game has been running with no modification at all on a 512 GB Steam Deck LED model. However, it has reverted back to having the white screen error on the Steam Deck OLED. I tried every versioon of Proton available in the compatability settings as well as tinkering with the game's launch configurator to modify FPS limits, resolution, and other settings.
Until an update is pushed by Valve this game appears incompatible with the OLED Deck.

I had to plug in dock after starting the game to use a external display.
If I wished to use a external display I had to plug them in after starting the game. Otherwise it would not start.

When launching from game mode while docked game gets stuck on a blank white screen. Solution is to either set resolution in properties to native, or whatever resolution the deck adopts while docked. The cause is a mismatch between default game settings resolution (1280x720) and deck resolution
It is needed a workaround to be able to play the game. On that configuration, some stuttering may be experienced.
Launched the game in desktop mode with a second monitor.
On default configuration in Game mode, the game will freeze at a white window.

In-game 30 FPS cap
There's little reason to go above the Medium graphics preset if playing portably, as all of the improvements from the High preset (AA, AF, Shadow res, AO res) are largely wasted on the Deck's smaller screen.
30 FPS vs 60 FPS is personal preference, though the game was originally designed for 30 on the PS2.
For a PS2 games, it doesn't seem well optimized and you'll have to run medium settings to get locked 60fps
