@steveowl – That suggests you have a typo – try typing
“nano /opt/retropie/configs/all/retroarch-joypads/X (then press tab to auto complete the name)

@dalehitchy What game/emulator are you testing with – how do you start the P2 player without a start button for it?

It looks like the issue may be resolved by adding this to /boot/cmdline.txt

Autofire on the axis

However, reading that thread as a whole would be helpful as many other people have the same issue – mostly resolved by editing that file – just make sure you do it properly in nano with a space after whats there then adding the new data based on your vendor id.
