Look at the top right corner of the game's cover art. Beneath the PlayStation logo is a small rectangular box. It reads "PAL" if the game is PAL, and "NTSC U/C" if it is NTSC.
Look on the spine of the game's cover art near the bottom of the case. Another small rectangular box is here. It will read either "PAL" or "NTSC U/C."
Open the game case and examine the game disc. Near the middle of the disc is a small rectangular box designating "PAL" or "NTSC U/C."
