Hi all

ive wired up a pi 3, a 4 buttons PCB, and all the button work up.down.left,right,A,B

however X Y don't work, I was wonder if I need to add a ground.

im using GPIO 20,21 not sure if thats right ?

Im using the 3.5 mm jack for audio and ive wired up a 3.5" cheap SPI screen.

ive enclosed my retrogame.cfg

LEFT 26 # Joypad left
RIGHT 5 # Joypad right
UP 13 # Joypad up
DOWN 6 # Joypad down
LEFTCTRL 4 # 'A' button
LEFTALT 17 # 'B' button
Z 20 # 'X' button
X 21 # 'Y' button
GND GND # Spare ground point for 'Y' button
SPACE 12 # 'Select' button
ENTER 18 # 'Start' button
ESC 12 # Hold Start+Select to exit ROM

All the buttons work except X and Y,

Also how do I get rid of the stats info off my SPI screen,

any help would be great

thanks
