1. "fulldouble=false" change to "fullbuffering=(off,double,triple)"
2. "fullresolution=original" to "fullresolution=(0x0x0,640x480x0,800x600x32)"
0x0x0 it will use desktop settings, 640x480x0 use desktop bit depth,
800x600x32 force 800x600 resolution and 32 bit color depth, the images must be stretched to selected resolution, and video system forced to work with 32 bit color depth must not to change screen (video restart), for example in dos use 4 bit color depth i enter to the game and it make video shutdown and re initialize it again, this must be avoided.
