So the name says more or less all .
When you pass a song in hard or insane , only in that diff you unlock the visual mods (no skin , no hitsounds , no SB , lower dim)
What I want to say is that you pass a diff , the easyer diffs on that song unlock too ,(In a song with easy, normal , hard , insane ,extra diff .If you pass the hard diff , only the hard ,normal and easy would be unlocked .If you pass the insane , all the previous should be unlocked and the respectivly song too , and if you pass the hardest diff , in our case the extra diff , the whole song should be unlocked ).If the map have another play mode too (ctb , taiko ) that should be unlocked normaly , not incluyed in the standard mod.
Edit 1
So more of you told me that this its not workin , but lets say that i fount a little diffrence betwin the diffs
Voilá
