Do note that you have to download the character and the .snd file in order to have those characters works. (Also after the extraction make sure the chracter folder is not in a folder by iteself. EX: Name_of_folder > Name_of_folder again).

Afterwards, place the .snd file into the character folder and place the character folder into the mugen's "chars" folder. After that its only a means of editing the select.def to add the chracter to the list.
