Car quantity over 16 cars and 255 laps

[sinaosal]

I had an idea to make RVGL be possible with over 16 cars and 255 laps.
I expiremented with the cheat engine (as Nickpalm suggested). I found out the value in the Cheat Engine, and i changed it (lets say 18). It shows up in the RVGL settings menu:

Number of cars: 18

I can modify the same with the laps:

Number of laps: 257

The game crashes.

Should i change the hardcoded value with the Cheat's Engine auto assembler or should i use a .dll (as Theman suggested)


Here are my questions:
How does the ZMenu RVGL do this (Add more cars) ? Can be viewed here:

Thanks in advance!
