Im presuming you have characters, and know hoew to unzip unrar etc... and have your character extracted to a folder3 steps i will use ryu for example1: open the folder, check the name of the .def file is the same as the folder that its inEgryu/ryu.def2: copy the folder to your chars folder in your Mugen install folderEgc:\program files\mugen\chars3: go to your data folder in your Mugen install folder, and open select.def with notepad. Inside this file has the instructions, like every file in Mugen (There actually no need to ask questions really) Anyway find kfm he is the default character. Under him add the line for your characterEg (to add ryu and get him to load on a random stage)ryu/ryu.def, randomdonePS if you want a video go to google and type the following:insatalling characters in mugen then click a video
all you need to add chars is reading the don'treadme.txt files and/or the select.def and some poor knowledge about paths
sometimes it works and sometimes it doesn't Does that mean there is something missing in the def file?
No, it means that your def file doesn't have the same name as your folder or that you're having problems writing in the select.def a name identic to the def file of the chr you want to add.
http://mugenpedia.de/en/Adding_Charactersmugenpedia.de said:At first you have to copy the character's folder in the chars folder of M.U.G.E.N. Pay attention to the folder structure. There must not exist a sub-folder so that the *.def file is readable.mugenpedia.de said:Furthermore you have to consider that the *.def file's name and folder's name are the same.
