I have a menu that need to be saved and never reset even you start a new game.
That menu contents are game progression, collectables items, new images on gallery, etc...
In the Manual it says to use global linked to option data, but I think for all this info the global will be to polluted.
It looks like you're new here. If you want to get involved, click one of these buttons!

What do you mean by "too polluted"?
Linking a variable to Options Data is the way to go if you want its value to be restored upon running the game's application, but not as part of individual save files.
