I don't know how it works on emulators. on smartphones, data/shaman king/files/epzone/ two files with the name LOCAL KEY and LOCAL CORE. if you delete them before linking to Twitter, the game will start again without additional file downloading. you do a reroll, as it is repeated, and then you link the account to Twitter. or don't do it, just save these two files somewhere on your phone, and after updating the game and the mod, insert them in their place.
