As for your point about the date 1989-02-21 which game do you refer to? I cant find any reference to this in any of your earlier posts.
There is none, it was just an example going by your logic of favouring a box print instead of ingame infos:
Being realistic if there is a boxscan / diskscan / manual available for the games they have to be the first point of call when it comes to renaming a game.
