If you move everything to under the heading “defaults” that should theoretically unlock them. (I haven’t tested this, so save a back-up of the file first.)
if you open unl.dat in notepad, you can see which items are unlocked, the unlocks.txt file has a list of all of them, so just copy and paste them all in unl.dat but make sure it’s still saved as unl.dat, not unl.dat.txt which notepad may try to do…
