How To Change The Static Background Screen To change the image you will need a replacement image in .BMP format that is sized at 720x480. Once you have your file ready we need to place it in the correct location. Open â€œThis PCâ€ or â€œFile Explorerâ€. Go to Documents>PlayCDG KJ Deluxe 64 LT>Utility. You will see a file named â€œScreenBGâ€, you can delete or rename this file. Place the new file here and make sure it is named exactly â€œScreenBGâ€. You have now set a new static background image.
