For Steam deck users: Refer to the Flatpak section.

Any distribution (Flatpak)

First you will have to open up a terminal and add the Flathub repository.

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

then, you can install the launcher by running the following:

flatpak install moe.launcher.the-honkers-railway-launcher

Flatpak has additional configuration options which you can view here

Arch Linux (AUR)

Using an AUR helper

You can install the launcher like any other AUR package using yay or other preferred AUR helpers.

yay -S the-honkers-railway-launcher-bin

Without an AUR helper

First you will have to clone the repository.

git clone https://aur.archlinux.org/the-honkers-railway-launcher-bin.git

Then move in to the repository directory.

cd the-honkers-railway-launcher-bin

And build the package.

makepkg -si

Note: Any missing dependencies not included in the base Arch repositories using this method will have to be fetched and install from the AUR manually.

Gentoo Linux (Ebuild)

Make sure that app-eselect/eselect-repository and dev-vcs/git is installed. After that add the launcher's overlay.

eselect repository add the-anime-team git https://github.com/an-anime-team/gentoo-ebuilds.git

And sync the repository.

emaint sync -r the-anime-team

Finally, emerge the launcher by running:

emerge --ask games-misc/the-honkers-railway-launcher

NixOS (nixpkg)

Cachix

It is recommended that you set up Cachix before the installation as not have to compile the launcher yourself. You can do so by running

nix-shell -p cachix --run "cachix use ezkea"

Or alternatively in a declarative way by appending the following to your configuration.nix

{
  nix.settings = {
    substituters = [ "https://ezkea.cachix.org" ];
    trusted-public-keys = [ "ezkea.cachix.org-1:ioBmUbJTZIKsHmWWXPe1FSFbeVe+afhfgqgTSNd34eI=" ];
  };
}

Installation

Add the following to your configuration.nix.

let
  aagl-gtk-on-nix = import (builtins.fetchTarball "https://github.com/ezKEa/aagl-gtk-on-nix/archive/main.tar.gz");
in
{
  imports = [
    aagl-gtk-on-nix.module
  ];

  programs.the-honkers-railway-launcher.enable = true;
}

Then install the launcher by running:

nixos-rebuild switch 

Flakes

Both the Cachix config and NixOS module are accessible via Flakes as well:

{
  inputs = {
    # Other inputs
    aagl.url = "github:ezKEa/aagl-gtk-on-nix";
    # Or, if you follow Nixkgs release 25.05:
    # aagl.url = "github:ezKEa/aagl-gtk-on-nix/release-25.05";
    aagl.inputs.nixpkgs.follows = "nixpkgs"; # Name of nixpkgs input you want to use
  };

  outputs = { self, nixpkgs, aagl, ... }: {
    nixosConfigurations.your-host = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        # Your system modules
        {
          imports = [ aagl.nixosModules.default ];
          nix.settings = aagl.nixConfig; # Set up Cachix
          programs.anime-game-launcher.enable = true; # Adds launcher and /etc/hosts rules
          programs.anime-games-launcher.enable = true;
          programs.honkers-railway-launcher.enable = true;
          programs.honkers-launcher.enable = true;
          programs.wavey-launcher.enable = true;
          programs.sleepy-launcher.enable = true;
        }
      ];
    };
  };
}

For installation through the nix package manager on other distributions refer to the instructions in this repository.

Any distribution (Executable)

Grab the latest binary from the Release page. Then set execution permissions for the binary.

chmod +x honkers-railway-launcher

And run the launcher with the following:

You will have to install any missing dependencies yourself.
