Hmm ok you started the game system up ok and you are left at the command prompt
... It's the same as dos at the end of the day
the game has not auto started so you will have to find the *.bat or *.exe that starts your game
dir = list all the files in current folder (use dir *.exe or dir *.bat when there are lots of files)
cd = change directory e.g. cd game
once you find the bat/exe files type in the name of the file and hit enter (you don't need the file extention typed in)
