COL flag
From Wexos's Wiki
This page describes the flags of Mario Kart Arcade GP DX COL files.
Collision Flags Format
The collision flag values are split into one 16 bit and two 8 bit groups. The 16 least significant bits determine the basic effect of the flag, the next 8 bits seems to be a sound variant, and the 8 most significant ones determine a special effect variant. In Mario Kart Arcade GP DX, collision is detected by polygon angle, meaning it can be either road or wall. Walls were not found into COL files except for the ones that connect a ramp with the road.
