CoolCV not recognizing d-pad

pajordan

i'm trying to use the CoolCV emulator on my GPi case (RetroPie 4.2 built from pre-made SD Image on RetroPie website running on a Pi Zero W).

i ssh'ed into the Pi and ran jstest (jstest /dev/input/js0) to determine my controller button and axes numbers. when i press up or down on the d-pad, this registers under axis 7; left or right register as axis 6.

i modified the first few lines of the coolcv_mapping.txt file (/home/pi/coolcv_mapping.txt) to reflect these axis values:

' CoolCV mappings for Colecovision controllers to keyboard and joystick
joystick_1_vert	joy0	axis7
joystick_1_horiz	joy0	axis6
joystick_2_vert	joy1	axis1
joystick_2_horiz	joy1	axis0
up_1	key1073741906
right_1	key1073741903
down_1	key1073741905
left_1	key1073741904
left_button_1	key32	joy0_3
right_button_1	key109	joy0_1
button3_1	key1073741939
button4_1	key1073741939
key1_1	key49	joy0_3
key2_1	key50	joy0_1
key3_1	key51	joy0_2
key4_1	key52	joy0_0

when i launch a rom, my controller buttons seem to be mapped fine - i'm able to start a game and use the controller buttons - but i can't use the d-pad to control the game character.

any idea on how i can get this working?

still curious about how to do this in coolcv, but i ended up trying lr-bluemsx instead and it works fine (all the controls were already mapped by default and work great).

Its very odd for a dpad to register as an analog axis what controller are you using?

@grant2258
it's the built-in controller for the Retroflag GPi case (http://retroflag.com/GPi-CASE.html) - i think it's connected like a USB gamepad, though i'm not sure.

thanks
