Youma Ninpou Chou, meaning "Demon Magic Technique Super," likely involved fighting demons using ninjutsu techniques. The 'alt' version suggests a variation either in graphics, gameplay mechanics, or game settings from the standard version. The developer and exact release dates for both versions are unclear and would need further investigation into Japanese arcade game archives.
