So here is the command line parameters needed to run the game:

supercan.exe -nx 270 -pl oyuncu -d defGSQ_3 -d defGPQ_3 -d defGTQ_2 -d defGMQ_3 -d defGGQ_1 -d defGEQ_2 -ip 00000000000 -sn null -d defGRX=1920 -d defGRY=1080


defXXX are for game quality, defgsq_0 being lowest defgsq_3 being highest etc. Check supercan.wdl for possible def_xxx's last 2 defs are initial game resolution.
