Allow user to set which box art, cart art, etc. should be used in edit menu

[darrel dearth]

allow user to set which box art, cart art, etc. should be used from within the edit menu when there are multiple versions found in the folder. right now the only way is to move the alternate arts out of the main folder because launchbox will pick one to use at random when more than one of a certain type is found.

By "edit menu" do you mean "game details pane"?
