1.) I once made a wild mix of "Hiragana, Katakana, Romaji and Kanj" using the DOS tool vgafed30. Just to get a glimpse of "how it could have looked"....as I cant find DOS/V and or japanese BIOS ROMS anywhere. 2.) Im also wondering if a "Sega Teradrive HDD dump" is existing anywhere and if the menus of the "TeraDrive" are stored as files or within the BIOS.
