Hi

I have a strange problem whereby in 2 player games (specifically 1943), both joysticks control the movement of both players. They are effectively linked on the screen. P1 fire buttons fire from P1 plane and P2 from P2 - it is just the joysticks that are the issue.

I have mapped the binds in Retroarch and have set up the controller settings in Retropie (although I am concerned that I didn't do something correctly here as it only gave me a player 1 option).

Any advice as to how to correct this?

Thank you

Peter.

@herts101 How is your controller detected in Emulationstation - in the Input Configuration - is it 1 controller or 2 controllers ?
There's a tidbit of info about Xin-Mo 2P controller in the docs, though it doesn't seem to apply in your case since your buttons are separately detected.
You can use the jstest program to check that it's not a wiring/hardware problem: run jstest /dev/input/js0 and jstest /dev/input/js1 and see if the P1 joystick moves appear when testing the P2 controls. More details here.

Input Configuration

Thank you. I've done a bit of testing as you suggested.

The controller is detected in Emulationstation as Gamepad 1. There is only the option to enter controls for one of the joystick/button combos as far as I can see.

I've tried jstest as you suggested and got different numbers for the buttons, but both joysticks changed the 0 and 1 numbers.

I'm sure this isn't a wiring issue as the joypad still works effectively with a previous pi as 2 seperate joysticks. I'm just upgrading the pi to a new fresh install on a fresh pi which has caused the problems.

Any other ideas?

Thank you again

Maybe worth saying that my controller.cfg file just seems to refer to 1 input as below.

input_device = "xin-mo.com Xinmotek Controller"
input_driver = "udev"
input_l_btn = "4"
input_load_state_btn = "4"
input_start_btn = "8"
input_exit_emulator_btn = "8"
input_down_axis = "+1"
input_r_btn = "5"
input_save_state_btn = "5"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_select_btn = "9"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"
input_up_axis = "-1"
input_a_btn = "0"
input_b_btn = "1"
input_reset_btn = "1"
input_enable_hotkey_btn = "8"
input_x_btn = "2"
input_menu_toggle_btn = "2"
input_y_btn = "3"

Solved it! The issue was with getting the Xin-Mo board to be detected as 2 gamepads. Thanks for the link on your reply @mitu

I got a lot of help from this link also https://blog.petrockblock.com/forums/topic/how-to-get-xin-mo-dual-arcade-working-with-retropie-easy-guide/page/2/, but please be wary that it is old and the changing of the kernel is not required for a Pi 3. It will brick the pi.

The process I used was as follows:

Exit emulationstation (F4)
Type lsusb to show the usbhid of your Xin-Mo controller. Note the usbhid of your controller. Mine was 0x16c0:0x05e1:0x040
Type sudo nano /boot/cmdline.txt
Move to the end of the line, press space, then add usbhid.quirks=0x16c0:0x05e1:0x040. If your usbhid is different then use your reference. Do not press enter or move to 2 lines in any way.
Save the cmdline.txt file
If you have already tried to configure a gamepad, then delete these files using sudo rm /home/pi/.emulationstation/es_input.cfg
Type: reboot

Then, when emulationstation starts again you will first be able to configure gamepad 1 (pressing one of the P1 buttons), and then go back in and configure P2 by pressing one of the P2 buttons.

Finally, you'll need to configure in retroarch. I had already done this so thought it was fine but the Select and Start P2 buttons didn't work. The solution was to reconfigure User 2 in retroarch, noting that there are now 2 Xin-Mo options under Device Index and User 2 needs to use the second one of these.

That link is the source material for the page in the Docs that I mentioned, only the configuration (i.e. adding the usbquirks module option) is required with the current release. Glad you got it working.

@mitu Thank you. Only remaining issue I can see is that the L1 and L2 buttons no longer page down the rom lists.

Is there something else I need to do to update the config for this to work?

Thank you so much for the help.

mitu

@herts101 Restart Emulationstation, should work.

herts101

I’ve restarted and still no luck. Any other ideas?

Thank you.

mitu

@herts101 I don't have any other ideas, I noticed that after first configuring the gamepad the L/R triggers don't work, but they work after ES restarts. Can you paste the output of the ~/.emulationstation/es_input.cfg file ? This is where Emulationstation stores the mapping for gamepads.

Thank you. File shows the following:

@herts101 Hm, this looks a bit different than the one I have. Try replacing leftshoulder with pageup and rightshoulder with pagedownin the file.
My configuration file looks like this (it's a SNES type gamepad) and has the pageup/pagedown functionality using the shoulder buttons.

<inputConfig type="joystick" deviceName="USB,2-axis 8-button gamepad  " deviceGUID="03000000830500006020000010010000">
    <input name="pageup" type="button" id="4" value="1"/>
    <input name="start" type="button" id="7" value="1"/>
    <input name="down" type="axis" id="1" value="1"/>
    <input name="pagedown" type="button" id="5" value="1"/>
    <input name="right" type="axis" id="0" value="1"/>
    <input name="select" type="button" id="6" value="1"/>

  </inputConfig>

Brilliant. Words perfectly. Thank you once again.
