Dataminers have been on a roll lately, and the trend has continued with yet another discovery that has been confirmed tonight. Dr. HyperCake, a dataminer, has discovered “Jack_Menentoes” within the strings of Super Smash Bros. Ultimate‘s LVD files. According to Dr. HyperCake, “the format of this string matches stage name strings in ui_stage_db”, which is usually (“[Series]_[Stage]”). Joker’s internal name is “jack”, so Joker’s stage may be Mementos. Dr. HyperCake’s tweeted the news, so we’ve included their tweet down below.
