Mugen, or M.U.G.E.N., is a free 2D game engine that lets you import characters, character stages and other assets commonly found in PC and console fighting games to create your own custom fighting game. Many developers and designers spend their free time creating custom characters that can add to your Mugen roster. As you have no limit to the number of characters that you can add, you can extract characters and edit files to expand your Mugen character roster.

Skill level:

Things you need

  • Mugen character folder

  1. 1

    Browse to the Mugen folder that contains the Mugen executable file and open the "Chars" folder. Copy the Mugen character folder to the "Chars" folder. If the character folder is in a ZIP file, double-click to extract it and drag the folder to the "Chars" folder.

  2. 2

    Double-click the character folder that you just copied and look for a file that has the ".def" extension. This file must have the same name as the folder in which it resides. If it does not, click to highlight the file and press "F2" to rename the file. Set the filename so the ".def" file matches the folder name but leave the ".def" extension intact. Note the name of the new character folder because you will need it in Step 4.

  3. 3

    Go back to the folder that has the main Mugen executable and open the "Data" folder.

    Click "Start," type "Notepad" in the search box and press enter. Drag the "select.def" file in the "Data" folder to the Notepad window to see its contents.

  4. 4

    Scroll down the Notepad window until you see the "[Characters]" section. Add the folder name of the new character below this section. Do not add the ".def" extension next to it.

  5. 5

    Repeat these steps to add more characters. Click "File" and select "Save" so you can use these new characters in Mugen.

Tips and warnings

  • In the "[Characters]" section, you will see all of the other playable characters in your Mugen game. Use this as a guide for adding other characters. As each line in the section represents a character, do not add a new character in the line next to an existing character but only above or below the line.
