USB Encoder Mapping

Still no luck when running the script directly.

Works for me - are you sure you're running a RetroArch emulator ? What game are you starting and what emulator appears in the launch command message ?

[bpm009]

Not 100% sure.I am running super mario kart and the SNES9X emulator.

[mitu]

When you start the game, there's the launch command 'splash', displaying the game and the emulator run:

What does it say when you start yours ?

[bpm009]

Mine says Super Mario Kart (USA) lr-snes9x2010.

[mitu]

Then it's using lr-snes9x2010 as emulator, which is a RetroArch core. I don't understand why it's not working - you can try adding the RetroArch network input config to \\retropie\configs\snes\retroarch.cfg, just in case you saved the configuration from the RGUI.

[bpm009]

Ok, good to know. I added the network input config to the snes config file. That still shouldn't have mattered when running the pause-ra.sh script in the terminal because isn't that simply running the PAUSE command the same as if I were running it in the game?

Edit: Ignore what I said above, that did the trick, I must have edited some configuration through the RGUI as you mentioned. You are awesome mitu. Can confirm everything from running in the terminal to pressing the P key does what it should do.

Now for my usecase I need to find a way to replace KEY_P 1 with a controller button that I want to have linked to a dedicated P4 or P5 (if possible) position. If I assigned the KEY_P to say "button 11" which no other controller of mine has, that should work right?

[mitu]

It should work, though you'll have to find out the event that triggers that. To find out the the right event, you need to:

• get the event device for the controller. Run cat /proc/bus/input/devices and note the /dev/input/eventX device of the controller you want to use. Let's say is /dev/input/event2.
• run thd --dump /dev/input/event2 from the terminal. Press the button and the event shold be shown on the screen:

thd --dump /dev/input/event2
EV_KEY  BTN_B   1       /dev/input/event2
# BTN_B 1       command

Press Ctrl+C to stop.
The event name is shown on the 2nd (commented) line - BTN_B, since I pressed the B button on my gamepad. Replace the KEY_P with the corresponding BTN_ event and it should work. Make sure to restart the service after re-configuration (sudo systemctl restart triggerhappy).

[bpm009]

Everything worked flawlessly, I really appreciate the event lookup code, I never would have figured that out. I did notice that if a hotkey was enabled that it does not work which I believe you mentioned in the other thread. All in all it does exactly what I wanted it to do.
