Koikatu in linux.

There are two ways to go with this:
- Using lutris (recommended, it's a game launcher, also easier/faster to update wine/dxvk later)
- Using system wine + dxvk

---------- Using lutris

Installation:
1) Install Koikatu (and dlc/mods) by extracting the rar/zip/whatever file(s) (your windows game install should work too).
2) Install lutris, wine-mono and winetricks with your distro package manager.
3) In lutris, in the left sidebar, right click on wine and select "manage versions", click on wine (i tested with 3.19, but should work with 3.10+) and wait for it to download.
4) In lutris click on "manually add a new game" (+ symbol in the tools bar). We're setting up the game now (if the options mentioned here are missing enable "Show advanced options" at the bottom left of the dialog):
    - Game info tab: put a name on it and in "Runners" select wine
    - Game options tab:
                        - in "Executable" click browse and select Koikatu.exe (wherever you extracted it in step 1)
                        - in "Wine prefix" select your wine prefix (most likely ~/.wine)
                        - everything else can be empty
    - Runner options tab:
                        - Select your wine version (3.10 or higher)
                        - Click on "Enable dxvk"
                        - in "DXVK version' select the lastest one (at the time of writting 0.95)
                        - everything else can be the defaults
    - System options tab (OPTIONAL):
                        -in "Enviroment variables" add the DXVK_HUD options you want (see https://github.com/doitsujin/dxvk#hud).
                        - everything else can be the defaults.
    - Click save and a new entry should show up in the main window.
5) Repeat step 4 but with CharaStudio.exe instead of Koikatu.exe for the studio.
6) In lutris, right click in the new entry (with the name you gave it) and select "wine configuration":
    - in the "libraries" tab: in the dropdown select "winhttp" and click "add" it will show up below as "winhttp (native,builtin)" if not click on "edit" and change it to that, click on ok when done.
7) Load a terminal and run "winetricks allfonts" wait for it to finish, it takes a bit of time.
8) The game(s) should run now when double clicking on the game entries (both the main game and studio) in lutris, it will have some stuttering issues at first (because of dxvk) but they will be gone after a few runs.

---------- Using system wine + dxvk

Installation:
1) Install Koikatu (and dlc/mods) by extracting the rar/zip/whatever file(s) (your windows game install should work too).
2) Install wine (3.10 or later, preferably the lastest one), wine-mono and winetricks with your distro package manager.
3) In a terminal run:
    - "wineboot" (OPTIONAL, only required if you didn't use wine before).
    - "winetricks allfonts" wait for it to finish, it takes a bit of time.
    - "winecfg" and in the "libraries" tab, in the dropdown select "winhttp" and click "add" it will show up below as "winhttp (native,builtin)" if not click on "edit" and change it to that, click on ok when done.
4) Install dxvk (either by using your distro package manager if it's available or following the instructions in https://github.com/doitsujin/dxvk).
5) To run the game open a terminal in the game folder (or cd to it) and run "DXVK_HUD=1 wine Koikatu.exe", make sure you get the DXVK HUD when running it, if not check your dxvk install, use "DXVK_HUD=1 wine CharaStudio.exe" for the studio. It will have some stuttering issues at first (because of dxvk) but they will be gone after a few runs.
