PPSSPP - Mapping Problem - Wireless Xbox controller

mitu

I think PPSSPP uses the SDL2 gamepad API to identify and map controller buttons - it may be worth trying to update it's mapping database.
Grab the gamecontrollerdb.txt file from https://github.com/gabomdq/SDL_GameControllerDB and replace the file in /opt/retropie/emulators/ppsspp/assets with it, then try again and see if the gamepad is handled better.

gamecontrollerdb.txt

I tried replacing the file.
Nothing changed.

I did more testing. I noticed one more thing.
While I'm on the menu and I push the Left Analog UP, I go down.
When I press Left Analog UP DOWN I go up.
Pushing Left and Right work as expected.

Here is what PPSSPP registers on button press when I try to remap the controls to the XBOX360 controller.

Dpad Up - pressing UP does not register anything
Dpad Down - pressing DOWN does not register anything
Dpad Left - pressing Left registers as pad1.Up
Dpad Right - pressing Right registers as pad1.Down

O - Pressing B registers as pad1.b3
X - Pressing A registers as pad1.b2
[] - Pressing X registers as pad1.b4
Triangle - Pressing Y registers as pad1.b1

Start - Pressing Start registers as ThumbL
Select - Pressing Back registers as pad1.back

L - Pressing LT registers as pad1.b9
R - Pressing RT registers as pad1.10

Analog Up - Pressing X registers as pad1.Y Axis -
Analog Down - Pressing X registers as pad1.Y Axis +
Analog Left - Pressing X registers as pad1.X Axis -
Analog Right - Pressing X registers as pad1.X Axis +

I had also updated the Xbox 360 controller driver.
No change occurred.

@theink try this

Edit:
/etc/modprobe.d/xpad.conf

Change
xpad triggers_to_buttons=1 to xpad triggers_to_buttons=0

Then remap your controller in emulation station. Then try remapping in ppsspp. I had a similar situation where I couldn't get the xbox 360 right analog stick mapped in ppsspp. This fixed it for me.

modprobe

Hi.
I'm keen on trying that, but that file seems to be inaccessible through my network and I don't have Linux to browse the card.
It seems to be something in PPSSPP that does not recognize the buttons correctly.

@theink from emulationstation drop to the terminal (f4) and type

sudo nano /etc/modprobe.d/xpad.conf

That will allow you to edit that file. Make the change I suggested above then press cntrl-x. It will ask if you want to save the changes make sure you say yes. Then type emulationstation to go back to emulationstation. Remap your controller and try PPSSPP again. It's a possibility that PPSSPP isn't perceiving the controller correctly because of that above option.

You can also try updating the xpad driver in retropie-setup.

@quicksilver
Thank you.
I will try that in the coming days. I don't have a wireless keyboard at hand :p

I did a complete test of the Xbox360 controller inside PPSSPP.
This is a list of the buttons I'm pressing and how PPSSPP recognizes them in the menu.

Main Buttons
Back - pad1.back
Start - pad1.ThumbL
X-Box - pad1.ThumbR

Directional Pad
Up - Don't Register!
Down - Don't Register!
Left - pad1.Up
Right - pad1.Down

Face Buttons
A - pad1.b2
B - pad1.B3
X - pad1.b4
Y - pad1.b1

Left Analog
L3 - pad1.Left
Up - pad1.Y Axis -
Down - pad1.Y Axis +
Left - pad1.X Axis -
Right - pad1.X Axis +

Right Analog
R3 - pad1.Right
Up - pad1.Pressure -
Down - pad1.Pressure +
Left - Don't Register!
Right - pad1.TouchMajor +

Shoulder Buttons
LB - pad1.b6
LT - pad1.b9

RB - pad1.b5
RT - pad1.b10

@theink Have you had any luck with this? I'm running into the same issue with a third-party wireless controller that I got from local Best Buy manufacturer. Weird thing is that it works well with the other platforms like SNES or GBA. First time I set it up, left analog joystick worked fine as well as A, B and Y but dpad, shoulders and X buttons didn't do anything Tried reconfiguring it on retropie setup screen and when I got back into PPSSPP this time dpad worked instead of left analog. Thank you

Hi.
I did not have time to research any further.
I can only guess what is causing the problem, but it is definitely something tied to ppsspp.

I guess that not enough people had stumbled on it yet. Hoping for an update from the retropie team working on ppsspp.

I have exactly the same problem with a Raspberry Pi4 4Gb installed in a PiBoy DMG handheld game case. The D-Pad functions incorrectly in the same way as the OP.

@quicksilver
It had passed 4 months before I actually tried your fix proposal.
It worked. The X-box controller is now fully compatible. Thank you!

@rodolfoaguilar @Firebird_WS6
I'm summing up what quicksilver proposed.
This solution worked for me.

Plug in a Keyboard
While in Emulation Station press F4 to open the Terminal
Type

sudo nano /etc/modprobe.d/xpad.conf

Change
xpad triggers_to_buttons=1 to xpad triggers_to_buttons=0
Press cntrl-x
Accept the changes.
Return back to Emulation Station by typing

emulationstation

Restart Retropie.
(In my case, I noticed that the X-box controller had started acting strangely while in Emulation Station.
The D-pad buttons swapped positions in Emulation Station as they were previously in PPSSPP.)
Remap the controller in Emulation Station.
Remap the controller in PPSSPP if necessary.
(In my case, this was not needed.)

I'm not sure why this issue is affecting some people and not others.
Apparently, the problem is caused by the Trigger buttons somehow.
