Its kind of hard to explain, because ive just started getting into decoding and other stuff since i Rig'N'Roll came out and im eager to edit the game files and make mods....
But for starters if you look into the Data folder and open the scripts.jar file with a jar extracter you can see all the scripts to the game
With this you can edit anything you wish such as game time and starting location for your truck too.
BUT the only thing that is holding me back is the SCH files that are alos in the DATA folder...Ive tried downloading programs that can open this but it says it is corrupted. So ive decided that it is a russian program that has encrypted the file, so at the moment im seeking help from modders on the russian side to help me out. When i figure a way to open these files ill let you guys know and provide a tutorial for it.
