With permission of Yohji I've added the KRP versions of the three tracks to my database. ( http://forum.kartracing-pro.com/index.php?topic=4785.0 )
Tsumagoi and Southern Circuit are nice kart tracks. (tsumagoi.pkz, Southern.pkz)
Gunma Cycle Sport Center is a long mountain track, maybe better suitable for WRS but I've added it nevertheless. (gunsai.pkz)
Thanks to Yohji, aoitori and nui (miyapon).
