M.U.G.E.N, THE FAN FIGHTING-GAME ENGINE, IS FULLY DECOMPILED AND REBUILT IN C

The M.U.G.E.N 1.1 fighting engine is fully decompiled

The M.U.G.E.N 1.1 fighting engine is fully decompiled

mugen-unleashed is a C reconstruction of the M.U.G.E.N 1.1 Beta 1 engine, Elecbyte's 2013 build of the fighting-game engine behind thousands of fan-made characters and crossover rosters. The creator says every function is now in C and was checked against the original executable with differential tests: the rebuilt mugen.exe writes the same log as the original on the title screen, VS and AI matches, menus and storyboards, bugs and quirks included. A native build is attached to the first release. Fixes and new features are left for later.
