What Ikemen GO is
Ikemen GO is a free, open-source fighting game engine for M.U.G.E.N resources. It supports Windows, macOS, Linux, Android, and iOS/iPadOS through stable releases and nightly builds. Lua scripting can add game modes and customizable story paths, while the ZSS language is used to program characters. Community-content compatibility is described as on par with M.U.G.E.N 1.1 Beta. Rollback and delay-based netcode support Internet versus matches and cooperative arcade or survival play. Minimum requirements include Windows 10 64-bit, macOS 13 Ventura on Apple Silicon, Linux x86-64 with glibc 2.35 or newer, Android 13 arm64, or iOS 17 arm64, plus a compatible OpenGL or Vulkan GPU. iOS/iPadOS IPA files can be sideloaded with AltStore, SideStore, or Sideloadly; free Apple IDs require refreshing the app every seven days. The engine uses the MIT license, while bundled screenpack assets use Creative Commons licenses.
