You know how you can download Kart tracks from Sega in Sonic Adventure 2? Is there any information on how to make custom tracks? I know the Kart tracks aren't already stored on the game disc, as the VMU files have different sizes (if they just enabled what was already there, odds are they would have the same size) and I remember Sega doing some contest or something where you can submit track designs and the winners would be made into playable tracks. I even remember reading the person who sent in the Eggrobo track design also sent in a clay model of the Eggrobo car. EDIT: (And a very late edit, 1/13/20.) I've changed the name of the thread, which was previously called "Sonic Adventure 2 Kart track editor?". If a moderator sees this, feel free to move it to "Engineering & Reverse Engineering"; I don't think I'm able to do it myself.
