Atari 5200 (jfroco version) - Help with second trigger? Never works on controller.

[tmo1138]

Pi Model or other hardware: Pi3 Model B ( from Canakit)
Power Supply used: (Supplied with Canakit) DCAR-052A5
RetroPie Version Used: 4.1
Built From: Pre made SD Image on RetroPie
USB Devices connected: Dualshock 3, Keyboard
Controller used: Dualshock 3
Guide used: :

Game: Choplifter 5200

And jfroco's rpi project https://github.com/jfroco/atari800-rpi

Everything works pretty well, except for using trigger 1 and 2 on the controller. That always seems to defer to the keyboard (Ctrl and Shift).

I've also reviewed @jfroco 's notes here to no avail:

Anyone else having this problem?

Sorry to hijack. I never knew that an alternative fork of the highly complicated A8 emu for retropie existed! Thanx for the info. I will have a try
