Homecoming Developers do not support any client bugs on Linux. If an issue cannot be reproduced in a Windows client, Linux specific bugs will be given a form response and closed without resolution. Please use the Homecoming Forums for Linux client support from other users.

Overview

It is possible to run City of Heroes on Linux through a technology called WINE (WINE Is Not an Emulator). By porting the Windows API libraries that City of Heroes uses to Linux, WINE effectively "fools" City of Heroes into thinking that it is actually running on Windows.

Instructions (Homecoming Launcher)

For sake of brevity, we'll assume you have a working Linux installation that is fully patched. The distro does not matter. Also assuming a 64-bit system and you can replace "usernameGoesHere" below with your Linux username where needed.

• Install Wine Stable using this download page -- https://wiki.winehq.org/Download -- Once there, pick Binaries, and your distribution. Follow the instructions for the Stable branch.
• Once installed the default Wine Prefix (/home/usernameGoesHere/.wine) will be made. It will prompt to install Gecko and Mono. Note that NEITHER library is necessary to run Homecoming: City of Heroes (although Mono will be useful if you wish to use Mids Reborn or other .NET apps later.) Another note worthy of mention -- it is not prompted during setup but you do NOT need to install Visual C++ Runtime at all. Wine handles this requirement automatically.
• Do one of the following (optional):

• Any Graphic Cards new from 2016 onward: Install either Lutris (GUI Launcher, check your package manager) or DXVK (Vulkan Library - https://github.com/doitsujin/dxvk - follow the instructions in the GitHub page using a terminal.) Lutris prepacks the DXVK library and is easier for new users if you don't want to touch terminal too much. Installing DXVK yourself takes up less overhead.
• Ubuntu and NVidia: Open "Additional Drivers" and make sure "Nouveau" is NOT selected. The NVIDIA 440 driver and newer will run City of Heroes (The NVIDIA 340 driver will work if you're on an older card.) For most users this is automatically handled (Pop_OS, etc.) but if the game performs terribly, please check this area before you give up.

• Run the Homecoming Installer. Choose your location on Drive C same as you would in Windows (C:\Games\Homecoming).

Once installation finishes you can run the game from /home/usernameGoesHere/.wine/drive_C/Games/Homecoming/bin/win64/launcher.exe using either Lutris or making a shortcut to the location. (For a Gnome-based distro, for example, it could be as easy as visiting ~/.local/share/applications, then copying an existing shortcut and naming it Homecoming.desktop, and finally edit the new shortcut in a text editor with correct values.)

System Requirements

Linux has different system requirements than Windows. For binary video card driver releases City of Heroes will only run on a current video driver that compiles with a Linux Kernel. When NVidia, AMD, or Intel drop driver support for a video card and the kernel fails to compile with the legacy driver in-place, you can no longer play City of Heroes on that system.

There is no specific date when this support ends; it will not be announced publicly when a software upgrade fails. The day that the video driver fails to recompile kernel modules for your current OS is when you need to decide. Possible fixes include:

• Run COH on an older OS instead of on the bleeding edge (ex. choosing Ubuntu LTS over the twice-a-year update distro) so older drivers continue to compile normally,
• Upgrade your hardware (baselines provided below to help in replacement), or
• set up your system to dual-boot to Windows and move your game files to Windows to continue play.

Linux Driver Support

• AMD: Cards older than RX 300 no longer have active driver development. (Current baseline: AMD RX 400/500 and newer.)
• NVidia: Cards older than GTX 500 no longer have active driver development. (Current baseline: NVidia GTX 600/700 and newer.)
• Intel: IGPs with GMA3000 or older are no longer patched. (Current baseline: Intel HD Graphics and newer.)

The above does not mean your older card will not work today. It means if it stops working in the distant future, this may be why.

Must Meet Game System Requirements

System Requirements are the same for a Linux system as they would be for a Windows system: 1 GHz Dual Core processor, 2GB of RAM, a video card capable of OpenGL 2.0/3.0, and 6-12GB free hard drive space. As a generality, if a system would not be able to play City of Heroes using Windows because of the hardware in use there's a good chance Linux won't work either.

ARM Linux

Homecoming Launcher (and more importantly the City of Heroes client) is not compiled for ARM. Wine will not run HCLauncher on an ARM system without a Software Emulator for X86 apps. Single-Board Computers (Raspberry Pi and variants, all use Broadcom) as well as Chromebook ARM chips that either have Linux app support (NVidia Tegra, Rockchip, Mediatek, Qualcomm Kyro or Snapdragon) or have ChromeOS replaced with Linux will not run City of Heroes with Wine alone.

A possible basis to start with would be QEMU, Box64, or a premade setup such as TwisterOS, but the broad swath of ARM systems available will not have sufficient hardware capability to expect useable performance to begin with.

How It Works

Programs that run on Windows do not directly access the hardware in the machine. For example, if a program needs a file from the hard drive, it does not talk directly to the hard drive, but it calls a function in the kernel, which in turn talks directly to the hard drive.

The primary advantage of this type of abstraction is that programs do not have to worry about the hardware-specific details of every device that is installed. Before this level of abstraction was achieved, every program had to have special drivers for every device that might be used. Now, only one set of drivers must be installed on Windows, which can be shared through a common set of functions that Windows provides (called the Application Programming Interface, or API).

A special set of functions may be grouped into a programming library. Such libraries typically handle some specific functionality. For example, there are two primary graphics libraries in use today to program games: Microsoft's DirectX, and OpenGL, an industry-standard graphics library. Since DirectX is a proprietary software library, programs that use it will typically only run on Windows. Since OpenGL has Windows and Linux versions, however, programs that run using this library are much more easily converted between Windows and Linux.

The open source community developed an application called WINE that provides a layer of abstraction between Windows programs and the system they're running on by taking the place of the Windows kernel and API. Among other things, it implements much of the DirectX library (converting the 3D parts to OpenGL). When WINE is installed on Linux, programs that use DirectX may be able to run, because they believe they are calling DirectX functions, and those functions work similarly under Linux and Windows.

City of Heroes in particular already uses OpenGL for its 3D graphics (while using DirectX primarily for input), which gives it a performance advantage when running through WINE.

Live Game (2004-2012) Installation

This section contains information that no longer applies to the current version of Homecoming: City of Heroes/Villains. It is provided for historical purposes.

Although City of Heroes works with Wine, the NCsoft launcher does not. There are currently two options for installing City of Heroes on a Linux system:

1. Run the NCsoft launcher to install City of Heroes on a Windows computer and copy the files to the Linux computer. Launch the game from the command line as "wine cityofheroes.exe -project coh -renderthread 0". The Windows computer doesn't need to be capable of playing City of Heroes, it just needs enough disk space to install it.
2. Use the unofficial City of Heroes launcher to install and run City of Heroes directly on Linux.

Paid Support

Codeweavers

The main sponsor of the Wine Project, Codeweavers, maintains a paid license of Crossover as a Prosumer Wine distribution offering tech support for use. It is important to note two things:

1. Paying for Crossover is not required to play Homecoming if you can install Wine on your own, however, it will work if you require paid Tech Support assistance instead of a Community-led forum.
2. Crossover's main customer base is business-class users. They will support gaming, but a lot of what Cedega did to simplify gaming use is not built into the application.

Cedega

This section contains information that no longer applies to the current version of Homecoming: City of Heroes/Villains. It is provided for historical purposes.

A company named TransGaming developed an application named Cedega that made the task of installing WINE and configuring Linux to run games much easier. Cedega was commercial software that required a $5 per month (or $55 per year) subscription fee to maintain the latest version, but many users use Cedega to make ease of installation and use of games running on WINE easier.

TransGaming went out of business in 2009, well in advance of the Live Game shutdown.
