Games: Pokemon Diamond (DS)
You hit the Y button and it should have a save game in the bottom screen of options. I think it is in the left column.
click the start or Y button and it should bring up the menu and in the menu go down to were it says save and click the A button then click yes and yes.
Press X and the menu will appear. At the bottom it says save. If it says overwrite the previous file then pick yes. And like it says, dont turn off the power until it says So-and-So saved the game.
