Euro Hot Hatch is another series i have installed but it does not appear in the 'Class' options and none of the cars are available as options for race weekend.
If this one doesn't appear in your CLASS options .... you surely miss a .gbd file in your install
Is it well this one: Hot Hatch Euro Challenge 2012 ?
In this case, look in Gamedata folder if you have those files: SIM_HHEC.gdb, SIM_HHEC.tga and SIM_HHEC.txt .... if you don't find them, that's a install mistake or you didn't install the whole mod.
And that's the reason why this class doesn't appear in game.
Those SIM_xxxxx.gdb are as important as the CLASSES=xxxxxx of the .car files.
Without the 1st ... the class doesn't appear .... without the 2nd... the car doesn't appear in the Class.
EDIT: in order to be complete:
- what appears above is the CLASS = the name coming in the first line of the SIM_XXXXX.gdb file
- for each CLASS, the choice appearing at the left is: the Special Classes of this same SIM_XXXXX.gdb file
- the car models appearing in the car choice are all cars included having those Class and Special classes in their own .car files.
Moreover: in those .car files you also have in the classes=XXXXXX the category in which this car is included..... this category in the one you see in the results or timing in the column at the right of the driver one.
For example, this could be ( if the SIM_XXXXX.gdb is prepared that way )
Class: Le Mans 24 hours ( choice at the top )
Special classes: LM1985, LM1986, LM1987 etc.... ( choice at the left )
Category: C1 - C2 - GTP ( appearing in one of the Timing or Results columns. )
