Well as far as menus go, you can't make menus of all reloadable things. You can't make a menu for year, manuf, numberPlayer, genre, etc. You can for items like the title, even the reloadable images like artwork_front and logos. Not so much for things like a menu of just fanarts. Of course it gets loaded for the the single item on screen but to have a menu that shows all on-screen items including the players for each game is a no go. A menu to show a default image for all on-screen items is a no go. You can only reload the single item in the menu.
Good example, look at the snes mini game menu. Underneath each game there is an image for the numberPlayers underneath each box. This I cannot do.
