I guess the real question would be how to operate the mod.
When I click on the enable mod button under options, the menu background animation and the sound stop, and the brightness fades for a few monents, and then it continues, but there is nothing changed, even when I restart and repeat the process. I also have the load on startup option checked, but it is to no avail.
I have a friend who downloaded Sins Plus a while back, and that included a different shortcut to open, but I know of nothing like that for 7 Deadly Sins.
I've been searching for a while, and can't find any forum help at all anywhere else, including here. The only post that had help stopped at clicking enable, and the person that was trying to run 7DS was stuck where I am.
