I posted the source code for entertainment purposes only, and I never seriously intended it to be compiled and run on another machine. Nevertheless, if you intend to run this on your own computer:

1. Make sure ScreenWidth, ScreenHeight, TOT_MINES are correct
2. Make the game window as big as you can. Try maximizing it.
3. Be sure that the entire game window is visible 2 seconds after it starts.

The calibration routine looks for intersections of dark lines, and if the resolution is too small, the lines change to a grayish color and you'll get "Calibration failed".

Detection is tricky and doesn't have a 100% success rate on my machine either. If it still doesn't work, you're out of luck xD
