Hi @Colo513 I guess you're using VPhoneGaGa Gold right? If yes, please do not use Magisk mod version here, please download Magisk 26.1 from GitHub. This will solve 9% error.
I tried emulators like MuMu and BlueStacks. It seems they can install the Magisk delta version, whose latest version is 25, but Shamiko requires Magisk version 26, and Vphonegaga does not work with the emulators. I don't have an Android phone to try either. Anyone who can share the way to work...
I go to folder "data" but can't find the package for this game "com.bandainamcogames.dbzdokkanww" so I can't backup the save game. So, where can I find the package? or how to make the package happen?
