 Through the use of codes before starting the game, the player can choose different characters for their playthrough, as well as display arcade-specific ROM information.As the code for displaying ROM information works on the Dreamcast version (though all data displayed is blank), it is believed that the codes will work on the arcade version as well.Codes can be entered anytime between the "Brought to you by Sega" audio at the start of the game through selecting "Game Start" on the main menu.
