1 button joystick to navigate retropie/emulation station

craggus2000

Hi,

Pi Model: 3
Power Supply used: official
RetroPie Version Used: 4.3
Built From: Pre made SD Image on RetroPie website
USB Devices connected: sometimes keyboard
Controller used: 1/2 Atari CX-40 via DB9 connected to GPIOs

Can anyone help please?
I'm trying to navigate and select emulators/games with just a 1-button joystick. It is connected via a DB9 socket attached to the GPIOs, using the mk_arcarde_joystick driver.
Up, Down, Left, Right all work as expected, but when I hit the button to select Atari2600 for example, it brings up the emulation station menu instead.
I have tried reconfiguring the joystick controller, remapping A and B, etc, and even swapping A and B in the emulation station setup, but I can't seem to get the correct setting!

What am I missing?
Any help greatly appreciated!
Thanks,

@craggus2000 I am not sure a one button joystick is optimal for navigating the emulation station menu. At the least it would seem you would need directional control (which you have) a button to confirm ("a" button), a button to go back ("b"), and start and select buttons to access menus. You may want to have a separate controller to navigate emulation station or use your keyboard. Then you could use your one button joystick for emulators that only need one button. I am far from an expert on this but seeing as no one else has replied yet I figured I would share what little I know.

Hi,
Yes in the end I decided to get a snes-style USB controller, and it seems to be working a treat!
Sorry for the delay in replying...
