如果開啓游戲會宕機，進入“控制器配置工具” 將解析度改為720p, 或關閉全螢幕（畫面會拉伸）。
If the Steam Deck system crashes on game startup, go to the "Controller Layout Tool" and change the resolution to 720p, or uncheck the fullscreen mode (the screen will stretch).
Custom wrapper script
In order to play with thcrap, while keeping Steam integration, use this wrapper: https://github.com/tactikauan/thcrap-steam-proton-wrapper
The game works perfectly fine out of the box in Japanese. Getting it to work with the English patch is a bit trickier.
Custom translation tool: https://www.thpatch.net/wiki/Touhou_Patch_Center:Main_page
While the game itself is handled with no problems, the thcrap translation patch proves to be annoying. The normal version of the program doesn't work, so I had to download the standalone version, rename "th17 custom (thpatch-en).exe" to "custom.exe" (backing up the original custom.exe first), and run the game by picking "Launch Configuration Tool". If it does work, I recommend deleting the thcrap_update.dll file inside the thcrap subfolder.
Aside form the missing character window when you start the game, the game runs as expected. The steam version is in japanese only so beware.
when you start the game, it first shows a windows with what i can only assume is used for what reolution the game hsould be run in, theres a lot of missing characters but if you press the button with question marks the game starts up as normal
Experienced no issues during play.
The game itself works perfectly. Check your window resolution, edit some options in the Configuration Tool, add JP locale, and that's it.
My video card is a bit old and does not support Vulkan.
Used the environment variable LANG=ja_JP.UTF-8 and installed Japanese locale to remove buggy japanese characters in the Configuration Tool.
Game crashes if you try to launch the game in a resolution bigger than your monitor and in full screen. Both the conditions need to be met, so launching in windowed mode or with a resolution smaller than your monitor in full screen is fine.
My final Launch Command on Steam is
LANG=ja_JP.UTF-8 PROTON_USE_WINED3D=1 %command%
If you're using on a non-60 Hz setup, Input Method (入力のレイテンシ) needs to be set to "Fast" (高速) or the game will run at the wrong speed. All details about the setup I did are available at https://gist.github.com/kazuyanakamura/85c85bc62ac5a10646c24b6b7cf7c134
Vulkan doesn't work with my GPU.
I've installed the following fonts via protontricks: fakejapanese, fakejapanese_vlgothic.
I also have inserted the command LANG="ja_JP.utf8" on "set launch options" to emulate the japanese locale, so the game displays the japanese characters then.
The game runs pretty much flawlessly.
Fullscreen is a no go.
The only issue is Japanese fonts will not display correctly in the configuration menu nor in the title (in the game everything displays perfectly), but the Thcrap patch fixes that issue.
Everything works perfectly except for fullscreen (game only works in windowed mode). No tweaks needed for 144 Hz monitor
