ROM Hack Just Dance 2020's into the unknown

[stellarr]

With this song being released only with an internet network, is there any way to get it? Say, a mod or a save file. I had the feeling that perhaps a save file that unlocked the song would do, is that the case?

 

[sillz]

are there any ways to add the online song lists to this game with a banned / offline switch?

unfortunately a save file with into the unknown unlocked does not unlock the song. doubt there's a way to add online songs
