Easy to use and implament skeleton of a config file. Requires Enhancement Pack installed. This will show you how to read from a file and setup the starting window to be on or off,

This is ready to be implamented quick without problem. Just be sure to have a file in the main directory with the exe that is named as what you have loading with something similare to:
1,800,600,32
1 = Window on, anything makes window off
The next 2 sections define first the width and then the height
The last one (in the example #32) will tell it the depth
