Navisoft Naviken 2.1 - Undumped Discs

From Redump Wiki

The HiSaturn (Sega Saturn) and Car Marty (FM Towns) car consoles supported Naviken formatted discs. This DAT is currently named after Naviken Version 2.1 format, but other discs in the same series may be eligible (please check with a mod before purchasing or submitting). The Navisoft series of discs had games (simple Quiz games) released, however the extent of this system's redump eligibility is not yet decided, so we do not advise purchasing these discs for the sole purpose of redump submission as eligibility may change in the future.
