Controller configuration per system and finding device index number.

matalog

In /opt/retropie/configs/all/retroarch.cfg it says

Device IDs are found in libretro.h.

Does anyone know where libretro.h is located?

Is there a way i could have searched for this file? I tried,

find / -name libretro.h -print but it said permission was denied on all results and then, i tried this logged in as root and it showed no results.

Thanks for any help,

Matt.

@BuZz Do you know where is is located on a retropie 3.8 device?

BuZz

It isn't - it's part of the source.

@BuZz # Sets which libretro device is used for a user.

Devices are indentified with a number.

This is normally saved by the menu.

Device IDs are found in libretro.h.

These settings are overridden by explicit command-line arguments which refer to input devices.

None: 0

Joypad (RetroPad): 1

Mouse: 2

Keyboard: 3

Generic Lightgun: 4

Joypad w/ Analog (RetroPad + Analog sticks): 5

Multitap (SNES specific): 257

Super Scope (SNES specific): 260

Justifier (SNES specific): 516

Justifiers (SNES specific): 772

So then, where it says device IDs above - it's not talking about controllers on my system?

BuZz

Please format your posts - see https://retropie.org.uk/forum/topic/3/read-this-first

These are the ids used internally by retroarch afaik - perhaps it would just be easier to explain what you are trying to do ?

I read that and assumed that I could order the player number of my controllers. It does look like that's what it is suggesting.

I became sidetracked when i was searching to see if there is anyway to have a controller specific configuration per system - do you know if there is?

@matalog in the documentation:

That doesn't seem to have all the information required - it doesn't mention how to find your selected joypads index - do you know how?

What i am looking to do is have my wii u pro controller use different x,y,a,b button number assignments from my ps3 pads - because they are numbered differently on the devices - both on the NES.
