Special Slots

Most tracks run on all slots, with exceptions of slots 4.2, 6.1 and 6.2; additionally, some tracks run only at slots 3.1, 5.3 and 7.1. Here are the rules for these special slots:

• Tracks can run on slot 4.2 only if they have at least one truck, car or bomb car and have the special MDL0 from the original track containing polygon11 and polygon60.
• Tracks can run on slot 6.1 only if ice.brres is present; furthermore this object is necessary to activate the icy water fall boundary flag.
• Tracks using objects HeyhoShipGBA and HeyhoBallGBA run only on slot 6.2 and they must use HeyhoShipGBA and the object pocha with water fall boundary flag to run.
• sunDS and pylon01 only work on slots 3.1 and 7.1.
• poihana sometimes doesn't work on slot 5.1; curiously, the object is used on this slot by Nintendo.

• All other slots are different for KCL Sound Triggers, particular sounds or GFX for KCL flags or what effects they give to tracks.
