How do you add characters to mugen

when you unzip the character put it or unzip it to the "chars" folder.Then copy the name of its folder. Now go to the "data" folder and open the select.def file with notepad or wordpad. scroll down until you see this line
kfm, stages/kfm.def

paste the name directly under . don't worry you don't have to do the stage thing unless your mugen is really old. hope this helps :)
