u should note something. do u need the desktop resolution or the game resolution ? they are different. and the game resolution is set by the video_mode in your display00.wdl.

the desktop resolution can be any resolution but when u using video_mode, it sets the game at that resolution.

1 - 320x200
2 - 320x240
3 - 320x400
4 - 400x300
5 - 512x384
6 - 640x480 - (default mode)
7 - 800x600
8 - 1024x768
9 - 1280x1024
10 - 1400x1050
11 - 1600x1200

U can set the video_mode to any resolution u want at the beginning of the game or use "video_switch" to switch between resolution after the device has been opened.
