nice work nanochess for coolcv buy the way, for the rasberrypi F7 is still not working. to find the commands to all button, I used an earlier version of coolcv. My only problem is that for my joystick up/down and left/right, the F7 tells me some thing like this "axis1 key-32767" but I am not able to put it in coolcv_mappings.txt, because coolcv clears this entry when I execute it.
