Activate 'Real Mode' Dreamcast BIOS menu
Go into Options, and select the Dreamcast Main Menu option, and set ANY icon. Once you have saved the new icon, the game will announce that you have unlocked Real Mode on the Dreamcast's menu. When you are on the BIOS menu now, pressing START will make the menu display in high-resolution 3-D graphics instead of the normal low-resolution flat menu.
