8Bitdo NES30 Pro Bluetooth controllers not registering right analog left and right positions properly

Rion

@GeekOB Have you tried older versions of the firmware for the NES30 Pro?

Here you can find all the releases for every 8bitdo controller that's been made from the official website. Not easy to find but it's there.

well after testing i cant my N30 Pro or FC30 pro to work once i update my Pi to version 4.4.9 and yes i have also gone up to version 4.4.11

i have downloaded all the firmwares from what @Rion posted and nothing seems to work, and yes i have uninstalled and reinstalled xpad drivers

so far nothing seems to work.

posted issue on github

@ExarKunIv Can you try updating your Emulationstation package ? There was a recent update for the SDL libraries and since Emulationstation is technically at fault here, it might help to test with the new updated SDL2.

EDIT: just to confirm, is your controller started in Dinput mode - otherwise I don't think the xpad driver would have any effect ?

ExarKunIv

@mitu I did update the Emulationstation package. No luck.

I'm not sure I get what mode you are talking about. As far as I know it is just a default one. The one that is just with the power button. I'm not pressing any other buttons when I'm powering on the controller

mitu

@ExarKunIv OK, then let's debug this further.

Exit Emulationstation, then from the terminal run

emulationstation --debug

Emulationstation should start in debug mode, and more messages are logged in it's log file. Run the input configuration again and map the buttons, then exit emulationstation.

Save the following files:

/home/pi/.emulationstation/es_log.txt
/home/pi/.emulationstation/es_input.cfg
/opt/retropie/configs/all/retroarch-joypads/<controller-name.cfg

Paste their output to pastebin.com so we can take a look and see how the input is managed by ES and the configuration file is generated.

@mitu thanks for getting back to me

heres what you asked me to do

es_log txt
8bitdo FC30 Pro cfg
es_input cfg

Looking at your controller mapping session, I see that RightAnalogLeft button is not mapped in Emulationstation

 Mapping [Axis 1-] -> LeftAnalogUp
Mapping [Axis 1+] -> LeftAnalogDown
Mapping [Axis 0-] -> LeftAnalogLeft
Mapping [Axis 0+] -> LeftAnalogRight
Mapping [Axis 3-] -> RightAnalogUp
Mapping [Axis 3+] -> RightAnalogDown
Mapping [Axis 2+] -> RightAnalogRight

The 8Bitdo FC30 Pro.cfg file for RetroArch (that you posted) is obviously also missing that part:

# Entries re-arranged for readability

# Left joystick
input_l_x_minus_axis = "-0"
input_l_x_plus_axis = "+0"
input_l_y_minus_axis = "-1"
input_l_y_plus_axis = "+1"

# Right Joystick
input_r_x_plus_axis = "+2"
input_r_y_minus_axis = "-3"
input_r_y_plus_axis = "+3"

Looking into a RetroArch auto-configuration file for a similar gamepad - see https://github.com/libretro/retroarch-joypad-autoconfig/blob/master/udev/8Bitdo_Pro_F30_BT.cfg -, I see that the joystick controls are similarly mapped, the only difference is the added input_r_x_minus_axis (i.e. the RightAnalogLeft missing from your mapping session in Emulationstation).

So, are you sure you actually mapped the Right Joystick Left trigger in Emulationstation and you didn't accidentally skip it ? Does it not register at all in Emulationstation in the input configuration dialog ?

ExarKunIv

@mitu nope i have done it more times then i would like to say. each time it just will not see it. i have skipped it and gone back to it. it just does not see it

but if i map it on a clean 4.4 load with out updating anything it will work like a champ.

but if i put the controller into switch mode. which Emulationstation will see it as a pro controller. then it will work. but i will have to remember that i need to boot the controller in switch mode each time

and i did use jstest and the 2 axes which it the right stick, left and right. it does show a number code as i move it about, both positive and negative

mitu

@ExarKunIv Can you download and install sdl-jstest and then repeat the controller testing ?

ExarKunIv

@mitu i really hate to ask, but how do i install it.

i hate to say but it is above me on how to go about getting it installed, sorry

mitu

@ExarKunIv In this case, I have a simpler test you could perform.
On your 4.4 clean image, update RetroPie's installed packages - but without updating the OS and it's packages. This should also update your RetroPie script and put it up to the current 4.4.11 (?) version. Try mapping again the controller and see if it works.
After this test, re-do the update, but this time choose to update the OS and packages. It will take considerably longer - but try again after that to map the controller.

Btw, if jstest shows the right joystick as working, a simple workaround would be to try and replace the controller's .cfg file with the one I posted earlier (https://github.com/libretro/retroarch-joypad-autoconfig/blob/master/udev/8Bitdo_Pro_F30_BT.cfg) - this should get you a functional right joystick in RetroArch.

ExarKunIv

@mitu ok so i updated just the retropie and NOT the OS.

i tried mapping the controller and -2 axis would not work. so i just started hitting anything to get pass the mapping.
so the hell of it i went back in and this time it worked. i was able to map -2 axis to anything. so i got it done and i went back in and again it worked.

not sure if this is normal or not. ( i just never payed close attention to it. but the mapping that failed was gamepad 1.
and next was gamepad 2, which worked.
and then gamepad 3 which worked.

is it this right. the gamepad number goes up as you map the controller even if it is the same?

im updateing everything right now. ill let you know what i get

mitu

@ExarKunIv said in 8Bitdo NES30 Pro Bluetooth controllers not registering right analog left and right positions properly:

is it this right. the gamepad number goes up as you map the controller even if it is the same?

The number is indicative of which controller you're mapping. If you have 2 identical controllers, there's no point in mapping the 2nd one - the config would be the same.

ExarKunIv

@mitu very odd

i have only one controller im messing with but yet it says gamepad 3 when i map it now.

i have updated everything now and i have able to map the controller correcly. i did it 4 times and each time it says gamepad 3.
but everything came up.

now why it mapped 3 different controllers i dont know.

think ill do a clean load. then update everything and see if i get a bunch different mappings like i have now.

mitu

I would suggest to reset your game controllers on the image that you started initially and try again to map your gamepad(s).

ExarKunIv

@mitu
i reset the controllers settings through Emulationstation

now its back to not seeing the -2axis on the right stick. i have done everything i can to see if i can get it to do the same thing as the other day and no luck.

also this is the 3rd Pi i have this problem with. and my NES30 pro is doing the same thing on my other build. so i know its not me being dumb :P

think ill try dropping the config you post earlier, but there is still a problem with something in Emulationstation i think

ExarKunIv

UPDATE

editing the .cfg and the ES input file for the controller and still nothing. the - axis for the right stick just will not been seen by Emulationstation

i also have tryed my NES30 pro. and that is also the same.

I have two FC30 Pro on firmware 4.1 using a fully updated RetroPie

They both map fine. I power on in the default mode by just pressing power button. Note that make sure you have them "registered" when they were in the right mode.

ExarKunIv

@BuZz
when you mean registered, that they show up with the correct name when im in the mapping menu?

BuZz

@ExarKunIv when you register/pair them via the Bluetooth config.
