There is a debug switch inside the ROM disabled in the release version of this game, similar to debug flags, used in other games by the same developer like in Captain Tsubasa J: Zenkoku Seiha e no Chousen. Game Genie code 620-12F-6EF will re-enable it. At the title screen press B to switch to the debug menu.
