So for my setup, I’m using a rpi2 with 3.2.1 installed using a Wi-Pi, Logitech K400r wireless keyboard and two Logitech F710 wireless gamepads. ES on startup recognizes both gamepads and after the joypad setup all buttons/axis are known. ES can be manipulated with both pads no problem. Select a Nintendo game rom and the first message on screen says something to the effect of “Press a key (or joypad button 0) to configure launch options for emulator/port (lr-fceum). Errors will be logged to /tmp/runcommand.log”. Very quickly thereafter, the emulator starts and I see in yellow at the bottom of the screen “Logitech F710 Gamepad configured in port #0” and “Logitech F710 Gamepad configured in port #1”. After the rom is launched there is absolutely no response from the keyboard or the gamepads. I have to power down rpi2 to restart everything.

It is clear that ES and the emulator are recognizing that the pads are installed but they don’t get configured to play. jstest gets responses from all buttons and axis controls. Interesting that when I select DosBox the keyboard is recognized and works. The DosBox emulator also reports the following “Two or more joysticks reported, initializing with 2axis. Using joystick Logitech Gamepad F710 with 7 axis, 11 buttons and 1 hat(s).” The second line is repeated for the other gamepad. I don’t see this when the game emulators are started.

Poking around in /opt/retropie/configs/all/retroarch.cfg I see “input_autodetect_enabled = true” and “joypad_autoconfig_dir = /opt/retorpie/configs/all/retroarch-joypads”. The directory does contain a mapping for the F710 controller but I don’t know where it came from. Looking further at retroarch.cfg I see “# input_libretro_device_p1 = ” for up to 8 players. When I uncomment two of those lines and set the value to 1, save and restart, I can launch and the pad works but not as I expect it to. Maybe I need to use a value of 5 because these pads have analog capability as well. I’ll try that tonight. I also found that there is no way to escape out of the emulator once it is launched. Back to the power cord for a reboot.

In the process of playing with this thing I also discovered that the “more” command is broke. It only displays one page then dumps you out to the commoand line. Good thing that “less” is also installed and works properly. I also found the at the game scraper has a serious problem when selecting “thearchive”. It takes several minutes between key/btn presses before it will accept another input. Default keyboard is set to “gb”, not “us” so piping Linux commands is impossible and some special keys are swapped on the keyboard. I’m sure there are more bugs yet to be discovered.

Please share any discoveries you make. I’m experiencing the same problem with a pair of Logitech F710 controllers on 3.2.1.
