Ikemen GO

IKEMEN Go is a remake of the IKEMEN (open source fighting games engine that supports M.U.G.E.N resources) in Google’s Programming Language “Go”.


For now automated build from AppVeyor can be found at:

Inside the artifacts tab. Installation bundles will be provided in the future.

If you need to install OpenAL dependencies, for windows, look at For other platforms, use the respective package manager.


On windows, execute Ikemen_GO.exe

On mac/linux, double-click on Ikemen_GO.command

Download the Mugen dependencies and unpack them into the Ikemen_GO source directory. Then, use Goland or Visual Studio Code to debug.

Cross-compiling binaries with docker (linux/windows/mac)

The easiest way to compile binaries for other platforms is with docker. You don't need the native development environment set to be able to build binaries if you decide to use docker. The image downloaded has all required tools to compile Ikemen_GO for all the three platforms.

Install docker for your platform. For mac, you can install using homebrew (brew cask install docker).

Open a terminal, go to Ikemen source directory folder and then run the script Look inside the script for details on how it works.

Preparing for release

Before generating the installation bundle, first make sure that the binaries for Ikemen_GO are properly generated. Download and install InstallBuilder. Once finished, open the program, then open the file releaseconf.xml. Click in Build. For other platforms, select the target platform then click in build.

You may edit releaseconf.xml or use the InstallBuilder wizard to customize the installer.

NOTE: InstallBuilder is free for opensource projects. But you need to get a license for it. Do not include copyrighted dependencies in the bundle.
