Solved Moonlight game controller mapping

[Jinuk Ahn]

I installed latest recalbox. I paired my ipega 9025 controller and It works well with kodi and ES.
But It doesn't go well with moonlight.
I found out auto generated gamecontrollerdb.txt includes wrong button mappings like below

0500000049190000020400001b010000,ipega media gamepad controller,platform:Linux,b:b168,righty:a3,rightx:a2,a:b167,x:b170,righttrigger:b176,rightstick:b181,leftshoulder:b173,dpup:h0.1,start:b178,dpdown:h0.4,rightshoulder:b174,dpright:h0.2,lefttrigger:b175,leftstick:b180,guide:b141,y:b171,lefty:a1,leftx:a0,back:b177,dpleft:h0.8,

I tried to edit it manually but every time I launch a game with moonlight, Recalbox overwrites it.

Any advise will be appreciated!

@jinuk-ahn why is it wrong ?

[Jinuk Ahn]

@Substring Axis mappings are right, but button mapping start at b167. It's obviously weird.

[Substring]

@jinuk-ahn so what ? what's wrong with it ? doesn't work ?

[Jinuk Ahn]

@Substring yes, It doesn't work. All buttons don't response. And that's why I wrote this thread.

@jinuk-ahn button numbers get that high especially if the pad also advertises keyboard. Reading http://upload.sunsky-online.com/res/drivers/PG-9025.pdf have you started it as gamepad mode ?

[Jinuk Ahn]

@Substring
Yes, I did. I connected my game controller into Windows 10 PC and tested it with a tool that can get sld key mappings http://www.generalarcade.com/gamepadtool/

03000000491900000204000000000000,Ipega PG-9023,a:b0,b:b1,back:b10,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,leftshoulder:b6,leftstick:b13,lefttrigger:b8,leftx:a0,lefty:a1,rightshoulder:b7,rightstick:b14,righttrigger:b9,rightx:a3,righty:a4,start:b11,x:b3,y:b4,platform:Windows,

I've got above in Windows 10. As you see button number looks more reasonable than Recalbox generated key mappings.

I found out that es_input.cfg also has unreasonable numbers on buttons.

<inputConfig type="joystick" deviceName="ipega media gamepad controller" deviceGUID="0500000049190000020400001b010000" deviceNbAxes="6" deviceNbHats="1" deviceNbButtons="183">

@jinuk-ahn that's because our sdl is patched yo find more buttons. But the patch was made by someone who had a good idea but made it dirtily. I really think about making this the rught way, but some pad configueations will be wrong, people will have to recinfigure their pads, most ppl will shout at us ...

[Jinuk Ahn]

@Substring
Thank you for your answer, Can you tell how to configure my controller manually? Or should I go back to Recalbox 4.1 and wait until SDL get patched?

[Substring]

@jinuk-ahn not 4.1, but the release before the Moonlight upgrade. Still, it should work, i should look at the Moonlight source code but i'm away for holidays

[Jinuk Ahn]

@Substring
Thank you! and spend nice holidays.

I found the solution, I write this for someone who have same issue.

I edited config files like below and it worked!

\RECALBOX\share\system\configs\moonlight (SMB)

gamecontrollerdb.txt - Duplicate and rename it ex)gamecontrollerdb_fixed.txt , Edit button number to what you got in SDL2 Gamepad Tool (http://www.generalarcade.com/gamepadtool/)

0500000049190000020400001b010000,ipega media gamepad controller,platform:Linux,b:b1,righty:a3,rightx:a2,a:b0,x:b3,righttrigger:b9,rightstick:b14,leftshoulder:b6,dpup:h0.1,start:b11,dpdown:h0.4,rightshoulder:b7,dpright:h0.2,lefttrigger:b8,leftstick:b13,y:b4,lefty:a1,leftx:a0,back:b10,dpleft:h0.8,

moonlight.conf - Uncomment mapping and write the path of edited gamecontrollerdb

## Default used mapping for streaming
## Searched for in $XDG_DATA_DIRS/moonlight or /usr/share/moonlight and /usr/local/share/moonlight
## Mapping can also be user overrided in $XDG_CONFIG_DIR/moonlight or ~/.config/moonlight or current directory
mapping = /recalbox/share/system/configs/moonlight/gamecontrollerdb_fixed.txt
