I want to use this Disgaea stage in MUGEN, but no matter how hard I search, I can't find it. I also searched mugenarchive, but couldn't find it there either. I know that the def file name is "IOFW.def" and the name is "Island of freedom and wealth". Since it was used in a Japanese video, it seems that this stage was created by a Japanese creator. Does anyone know where to download this stage?
