So basically in the freeplay (and only freeplay) menu I can add custom difficulty’s, and I’m planing to add these difficulty (Hard (normal), V3, V2, V1/V5).

I was gonna add 2 more (F3 (The F3 trailer build of Vs Impostor) and PreV4 (the beginning development of V4)).

And some song may have special difficulty (Like Erect, remixes (from official devs), hotfixs remasters, and some stuff like that).
