Works out of the box
Game runs out of the box. No Proton compatibility issues.

Protontricks is required to install this: https://github.com/b-fission/vn_winestuff
Don't bother using protontricks to install WMP11, it will cause the game to crash. Instead, do this:
- Clone this git repo: https://github.com/b-fission/vn_winestuff
- Run protontricks and select your game (in this case, "NEKOPARA Vol. 3: 602520"}
- Dismiss a bunch of warnings complaining that it can't detect the bitness of your Wine setup (these days it's WOW64 by default)
- Keep "Select the default wineprefix" selected, hit OK
- Select "Run a commandline shell (for debugging)", hit OK. This will fire up your default terminal emulator, now configured to run Wine/Proton within your game prefix
- On the just opened terminal run the following:
export WINEARCH="win64"
bash /path/to/your/vn_winestuff/codec.sh quartz2 wmp11
winecfg -v win10
This should be enough to get the OP/ED movies working, for those that absolutely want them (hint: you paid for them, so you do!)
The OP/ED movies will not play without tinkering, but the engine (Kirikiri) will just skip them. Other than that, everything works flawlessly, so enjoy your catgirls and your pervy patissiere~

The game is fully playable, you will only miss the OP/ED movies, everything else works fine
Opening/ending videos do not play at all - the game just skips them. This is most likely due to missing GStreamer components to demux/decode WMV/ASF files (which are used by this series).
This is a visual novel built on Kirikiri, where use of WMV videos is common. FWIW, usually Kirikiri+WMV VNs work fine on vanilla Wine after installing gstreamer-libav and gstreamer-plugins-ugly (which provides the ASF demxuer required for this format). Unfortunately the savegames for the Steam and non-Steam versions of Nekopara (yes, I paid for both!) are not compatible, so I can't really test video playback on upstream Wine unless if I play the game all over again.
Worked after switching to Intel Power Saving mode in Optimus (Intel Arc is fun, ain't it?)

Launches, freezes, then exits. No game window even pops up. No error message.
Proton log file says 'MESA-INTEL: warning: cannot initialize blitter engine'. Game worked fine on same hardware on Windows 10. Appears to be an Intel Arc Linux driver problem.
When fullscreen is enabled, moving the cursor to the top of the window to access the top toolbar freezes all of KDE Plasma, requiring me to reboot. Playing windowed or just avoiding moving the cursor too far upwards can avoid this.

install directshow and wmp9
Cannot delete save file
Install directshow and wmp9 to play OP (GE-Proton8-11)
Game works out of the box for the most part and runs very well. Fixable issues with resolution by changing to Native.
If the resolution shows up as pixelated, change the Steam settings of the game to Native resolution instead of default and it will fix it.
Couldn't delete save files without game crashing. Not a huge deal, can still be overwritten.
Basically works out of the box.
PROTON_USE_WINED3D=1 %command%
install wmp9
Install wmp9 to play OP.
LANG=ja_JP.UTF-8 %command%
install wmp9
Lauguage is traditional chinese. LANG=ja_JP.UTF-8 %command% to fix the square fonts in the menu bar. Install wmp9 to play the OP.
Changed to Use left click to advance text
Reduce TDP to 5W with no difference in performance
Steam Input bindings don't function in game mode unless the game is changed to windowed. Fullscreen bindings work fine in desktop mode.
Only the settings have some small text that is harder to read

Steam Input does not load the mapping in gaming mode
The specified custom controller mapping which makes the game a better experience on the Deck doesn't load correctly on the Deck gaming mode for some reason and only a few of the buttons work. In desktop mode it loads fine and the game is totally playable.
perfect, no tweaks
No issues at all
Work's perfectly out the box.
Runs like native.

Worked OOTB
This game crashes on startup on Windows 10 for me, but it works fine with Proton 5.13-5.
I was surprised that all my saves were synced to/from steam cloud from when I played this game years ago on Windows 7.
In this volume, I didn't notice any plot holes from a missing movie that others were reporting.
Opening and ending movie didn't play
When switching from fullscreen to windowed and back to fullscreen, the game would softlock my system.
Adding this command as a launch option on Steam helped fixed the blank/square Japanese fonts.
LANG=ja_JP.UTF-8 %command%
Live2D (and almost whole E-Mote engine) doesn't work properly on latest Proton so you need to roll back to Proton 4.11-13 to have the the characters appear on the screen
Going from fullscreen to windowed somehow shrinks the window without user input. It's best to leave it as default since you run it for the first time or go ahead to fullscreen. But then, it has problem going with fullscreen that it doesn't scale to fullscreen properly.
The OP and ED doesn't play and I haven't found any fixes, yet.
- Movies did not seem to play
- Japanese text rendered as boxes (while chinese text was good)
As long as you're using Proton 4.11-13 + "wmp11" protontricks verb, the game will run very well.
The new "wmp11" winetricks verb is required for video cutscenes playback. Install protontricks, then install "wmp11" verb with "protontricks 333600 wmp11". More info about the verb: https://github.com/Winetricks/winetricks/pull/1489.
Jiggle effects from moving around the game's window aren't working. Pressing P for the jumping jiggles is working as expected though.
Graphical regression with Proton 5.0-5. The Direct3D E-mote (live 2d avatars of the girls) won't appear, or in rare cases will appear semi-transparent. No issues with Proton 4.11-13.
Works like a native game, patch included (both Steam and third party)
Your system will need the Japanese locale set for Japanese text it seems, but other than that everything works including patch both from Steam and from a third party site like Denpasoft if you bought the patch that way.
To enable Japanese text, use the launch option (for Mint at least) "LANG=ja_JP.UTF-8 %command%". For whatever reason, LC_ALL isn't respected, but LANG is. If this isn't sufficient, as it likely won't be, run "sudo dpkg-reconfigure locales" and check ja_JP.UTF-8 in the list, then confirm to recompile the system's locales with support for ja_JP.UTF-8 added.


Games runs perfectly fine except for Japanese dialog (rendered as square boxes)


Perfect


It just works. Awesome.



Works perfectly. No tweaks needed.


Works out of the box run trough the full game


Japanese text won't display when system language is English. Changing system language to Japanese works perfectly


it works perfectly only that it lacks to the sources of the other languages that are with bugs but the English language takes normally also does not work the opening and nor the ending outside it perhaps with future updates of the proton correct those problems
