You\'re referring to the Memory Card control panel. When you turn on the console without any game, it gives you 2 options: Navigator and Memory Card. If you select the Memory Card option, you will see the info saved in your memory card, the size of the saved games, info, etc. Those options you said (copy, delete) are only operations at memory card level. I mean if you select copy, you will copy a saved game to another memory card in slot 2.
In order to begin your GT3 with a previous saved game, just insert the disc and reset the system. It will load automatically the saved game and you will be able to continue the license or whatever.
If it doesn\'t load at the game\'s starting, you should check the game options and see if auto-load is active.
