CAPs inject variables into GP4.exe
For example, in the IMSA mod I'm working on, as they are long-term races, the number of races can be set (for example 3,6,9,12,15 or 17 by default). That allows you to make the .cap file
To do this you must edit the CAP file with a hex editor. (remember to use the decimal to hexadecimal conversion table to check the values)
This example sets the championship duration to 9 races
