Summarize the following:
Push the blue triangle with a single line beneath it. The door of the disc holder will now be open. The screen will freeze momentarily, which is fine. Take the disc out gently. You may hear a click, which is normal. Close the door to the disc holder by hand. Plug your controller into Slot 1/A, and ensure the memory card is properly inserted into the console. The port is located on the left side of the console, just on top of the controller port. Plug in your PS2 and connect it to your TV. Make sure the proper cables are attached. A red light will appear on the power button at the front of the console. Press the button and the light will turn green.  Using a button labeled "Source" or "Input" on your TV remote, go through the inputs until you find one where you can see your PS2's visual. If there is a game in your PS2, the start menu for that game will appear. Make sure it's highlighted in light blue and push the blue "X" button on the right side of your controller to select. The screen will have a grey background, which means you should now be on your browser screen. If your memory card is inserted correctly, it will appear as a little rectangle on the screen.  The contents of the memory card will appear once it is selected. It may take a few seconds depending on how full it is. All the data on that PS2 memory card will pop up in rows. Skip this step if the console recognized the card. Using the arrows on the left side of your controller, select data that you want to delete. Use the logo, theme, and name of the game to identify the data you want to remove.  Each piece of data is a picture that corresponds with the said game, or configuration data. (For Example, Final Fantasy would have a Chocobo, or Soul Calibur would have the logo and so on). You will slowly see 3D renderings of games that have saved data on the memory card. When there is a white light on a rendering, it means it is selected. Note that if you see the name of the game but the data icon is a blue cube, then the data is corrupted and therefore cannot be deleted or removed. " Once you've selected the data that you want to delete, a screen should appear. It will bring up the icon along with two options: "Copy" and "Delete." Ensure that you are deleting the correct data, as there is no undo button. It may ask you to "Confirm'/'Are you sure." If so, and you are sure, select "Yes." Press "X" and the data will be deleted. If you don't want to delete the data press "O." Make sure to read the foot-note. The data is removed and you have now freed up space on your memory card.

Summary:
Eject and remove any disc before you turn on the console. Turn on the PS2 console. Select "Browser" from the standard PS2 menu screen. Highlight the memory card and select it by pressing the "X" button. Find the data of the game you want to delete then push the 'X' button. Use the arrows on the controller to highlight and select "Delete. Exit the screen by pressing the triangle.
