    For Gradius III: Only stages that you have reached will be available in stage select.
    For Gradius IV: You must complete the game to unlock this option.
  • Option Mode: Allows you to select game options. Options chosen in this mode will only affect the game you're in.
  • Main Title: Brings you back to the main menu which allows you to choose between Gradius III and Gradius IV.

Option Mode[edit]

  • Save/Load: Allows for saving and loading of high scores and progress for Stage Select.

Options Exclusive to Gradius III[edit]

  • Wait Level (Off/Level1/Level2): The PS2 processor is much faster than the original arcade hardware, therefore the amount of lag present on the original arcade game can be toggled on and off.

  • Sound: Allows selection of Stereo or Mono sound.
  • Screen: Allows selection of Arcade or Full-size views.
