⚠️

This port isnot officially endorsed byNekoNyan,Aokana's applause-worthySteam publisherand English localizer. We still love you,NekoNyan.

1. Please legally purchaseNekoNyan's English localization ofAokana, becauseNekoNyan continually goesbeyond the call of corporate duty to support censorship-free localizationthroughout the English visual novel community. Online storefronts include:
   • NekoNyan themselves.
   • JAST.
   • Steam.
2. DownloadLinux-compatible videos in the language of your choice:
   • English and/orJapanese.
   • SimplifiedChinese.
   • TraditionalChinese.
3. Choose the installation route that's right for you:

   • "NekoNyan orJAST, please." But ofcourse, cultured senpai! This route installs theAokana PerfectEdition+ R18 release directly purchasedfromNekoNyan orJAST (identical to theuncensored Steam release detailed below). Either:

     • (Recommended)InstallAokana from the Lutriswebsite:
       1. Browse to theLutris Aokana page.
       2. Click theInstall button to the right of theLINUX WindowsNekoNyan or JAST version installer.
     • Manually install Aokana from this repository:

       1. Download ourwell-tested NekoNyan-or-JAST Lutrisinstaller.

       2. Open a terminal to the directory containing that file.

       3. Copy-and-paste this command into that terminal:

          lutris -i aokana-native-nekonyan-or-jast.yml

   • "Steam, please." Your wish is our Linux command. OurSteam installers are experimental, largely untested, and possiblyeven (but hopefullynot) broken. Please help us get a better idea of thestate of these installers bysubmitting a new issue documenting yourinstallation experience. Note thatNekoNyan'svanilla Steam release ofAokanais thecensored All Ages version. Some people like that. Some peopledon't.^{Obligatory shoutouts to/r/visualnovelshere.} Again, choose the installation subroute that's right for you:

     • "Censored, please." Sure thing! It's your visual novel. Thissubroute installs thecensored All Ages vanilla Steam release ofAokana:

       1. Download ourexperimental censored Steam Lutrisinstaller.

       2. Open a terminal to the directory containing that file.

       3. Copy-and-paste this command into that terminal:

          lutris -i aokana-native-steam-censored.yml

     • "Uncensored, please." You have chosen wisely. This subrouteinstalls thefree-as-in-beer Perfect Edition+ R18 Steam DLCpatch restoring all CGs, scenes, anddialogues from the original Japanese release as well as adding Misaka'ssupplementary scenes from the so-calledAokana Perfect Edition+:

       1. Download ourexperimental uncensored Steam Lutrisinstaller.

       2. Open a terminal to the directory containing that file.

       3. Copy-and-paste this command into that terminal:

          lutris -i aokana-native-steam-uncensored.yml

   • "Unspecified other sources, please." Please legally purchaseNekoNyan's English localization ofAokana when you havethe financial means – if you haven't already, of course. Without ongoingmonetary support, the visual novel community will get a BAD END (which isbad):

     1. Download ourwell-tested portable Lutris installer.

     2. Open a terminal to the directory containing that file.

     3. Copy-and-paste this command into that terminal:

        lutris -i aokana-native-portable.yml

     4. When asked toSelect main Windows executable "Aokana.exe", selectthe top-levelAokana.exe file in the directory containing yourportable Windows copy ofAokana.

You're done. Praise Misaka!

This port is afan-authored third-party conversion ofNekoNyan'soriginal Windows-only release, nowfeaturing:

• Native Linux execution. As a native Linux application, this port requiresno compatibility layer (e.g.,WINEProton) – reducingruntime overhead and the usual laundry list of issues caused by these layers.
• Linux-compatible videos. As a native Linux application, thisport leverages cross-platform open-source royalty-free media standards likeVorbis,VP8, andWebM rather thanthe non-cross-platform non-open-source royalty-encumbered media shipped withtheoriginal Windows-only release.
• Fast save restart. This port additionally supports a new low-level--continue command-line option substantially reducing startup times. Whenpassed, this option bypasses all startup logos, the opening video (OP), themain menu, and the load menu by immediately loading straight into the mostrecent save.Nice.

This port also features a number ofmostly negligible differences from theoriginal Windows-only release, listed here for bothcompleteness and to avoid confusion:

• Sprite Viewer file features unsupported. This port doesnot currentlysupport Sprite Viewer features attempting to open a file dialog, as theoriginal Windows-only release did so by opening anon-portable Windows-specific file dialog. This includes the following SpriteViewer features:
  • Background importation.
  • Image file saving.
• Letterboxing on window resizes. When manually resizing the game window toan unsupported aspect ratio, this port currently letterboxes (i.e., surroundsgame content with both horizontal and vertical black bars) rather thanauto-correcting itself as in theoriginal Windows-onlyrelease.
• Unpaused audio on window minimization. When minimizing the game window,this port currently fails to pause the currently playing audio if any ratherthan automatically pausing that audio as in theoriginal Windows-onlyrelease.
• Save thumbnail degradation. As in the Switch port, this port downscalessave thumbnails with Unity's lower-quality stock bilinear filtering moderather than the higher-quality bicubic filtering mode implemented by theoriginal Windows-only release.

Authoritative credit for this native Linux port goes entirely toUnity maestroand Fuwanovel forums contributorloam, whoseinitial post ignitedthe whole shebang.You are amazing and you surely know it.
