The format of cc-line is so:
I'll start with offset 0x3812 at monza byte listing.
1f 00 00 00 00 60 are 3 integers. The first means length of CC-line 
sector. The second is some adjustment, I'm working on it. The last 
integer is a radius of the curve. The smaller number the sharper 
corner. I don't know, how this can be processed as fast as is in the 
game, but it works.

The algorithm is so
let's say we have the two values in these vars

float len, float radius;

I need a global angle
angle=0

and an angle increment
angleinc = 1 / radius   <- this is it

for i=0 to len do
  angle += angleinc
  float x = cos(angle)
  float y = sin(angle)
  draw_line_towards(x, y)  // draws line from the last place
