Hey i'm currently doing the Senran Banka Switch version as well, had any luck on it since? Thank You very much for updating it to make it work with Switch version's .dat files!
P.S. why can't they just fucking use .xp3 like the PC version? tryin be different 'n shit, makes things more compilated then it should or unless these companies are fully aware of the modding scene...
Edit: your tool doesn't work at all, how the hell do i use it dude?!
