COD4 Need help with saving data

[Tally]

I just tested it fast, made link to iw3mp.exe and added +set dedicated 2

map mp_bog
set foo 123
map_rotate
foo ------> will print 123, as expected from CoD2

So cvar is clearly there, right? Or GSC cannot access them?

Edit: I just recalled the functions are named setdvar(key, value) and getdvar(key) in CoD4.

Just tested on my dedicated COD4 box - didn't work.

Next!
