Instructions
Go to the GameFAQs website and search for your desired game.
Click "Save" to view a list of saved games, if any.
Click the saved game you wish to download. Confirm your download folder and wait for the process to finish.
Open the folder where you downloaded the save. Open your game's save folder in a separate window. This exact location will vary, but it is usually within the game's installation folder or in the Documents folder.
Drag the downloaded game save into your game's saved game folder. This automatically installs it into the game, and you can load it the next time you play.
