Ok, so just to make sure I wasn't missing anything, I did the following...

Re-download and install RetroPie. Connect to WiFi and install updates. Download and install ControlBlock driver from RetroPie setup. Configured new controllers on startup.

After doing some more testing, I discovered that my conltrol settings responded the same for NES, SNES, and all lr-* arcade emulators. Anything using mame4all seems to be governed by different setting. So for the moment, I'll stick with libretro emulators.

Now, when I go in to RetroArch from the RetroPie setup menu and make changes to the button configurations, a few things happen. Setting buttons for Restart and Quit RetroArch requires that I set a button for Toggle Hotkeys. I'd prefer not to have to do that. Making those button changes also causes Select+Start in NES and SNES to stop quiting RetroArch.

I feel like I'm getting closer, but the hotkeys are still throwing me off.
Any thoughts? Thanks.

@SanyaIV said in Run custom action on custom hotkey?:

What I want to do: ADD a hotkey that does a CUSTOM action.
The hotkey: DualShock 4 contoller [Share] + [PS Button]
The action: Run a script (The script will toggle vcgencmd display_power 0 and vcgencmd display_power 1)

Hi Sanya,

Maybe you could achieve what you want by using Triggerhappy with configurations like here?:

A nice kid-friendly prevention.

I set it directly in /opt/retropie/configs/all/retroarch-joypads/THTTHTArcadeconsole2PUSBPlayer.cfg

input_enable_hotkey_btn = "8"

If I use the Retroarch menu (Settings/Input/Input Hotkey Binds/Enable Hotkeys), I can't set it to 11 because is on js1. I can only set button from js0.

Ok, last ditch effort. When you launch a game, the box pops up onscreen. That is the launchcommand box. When you press a button you go into the launchcommand dialog where you can set video modes, etc. If you go into there, one of the options is "EDIT CUSTOM RETROARCH CONFIG FOR THIS ROM" - try typing the code manually into that area and saving. That will create the config file in your roms folder that you can edit further if needed.

If the file is created, and the effect still doesnt work, try putting nul in quotes ("nul") OR put a random number in there that the controller cannot support "99" would pull a button that doesnt exist.

If that doesn't work, im not sure what to tell ya, i use this method all the time for my arcade roms because they dont have consistent controls. I would use remapping but my arcade is all keyboard controls so retroarch config file edits work fine.

@bassman6805
Look in the /opt/retropie/configs/all/retroarch-joypads/ directory and there should be a .cfg file with your controller settings in it.

For example I have a wireless Xbox 360 controller so mine is:
/opt/retropie/configs/all/retroarch-joypads/Xbox360WirelessReceiver\(XBOX\).cfg

In your version of that file you can put your hotkey settings. It will be in what looks like a random order.

I believe the ones for your controller will end with _btn
https://github.com/retropie/retropie-setup/wiki/RetroArch-Configuration#hotkeys
Another example:
input_enable_hotkey_btn is for controllers and input_enable_hotkey is for the keyboard.

I have manually re-organized mine so I can read it easier but here is my hotkey section

# Hotkey button input_enable_hotkey_btn = "8" #Select # Exit emulator input_exit_emulator_btn = "9" #Start # Saves state input_save_state_btn = "1" #B button # Loads state input_load_state_btn = "2" #X button # Move to next save state slot input_state_slot_increase_btn = "5" #R button input_state_slot_increase_axis = "+0" #Right on D pad/Left Stick # Move back a save state slot input_state_slot_decrease_btn = "4" #L button input_state_slot_decrease_axis = "-0" #Left on D pad/Left Stick # Reset ROM input_reset_btn = "0" #A button input_reset_axis = "-1" #Up on D pad/Left Stick # Toggle RetroArch menu input_menu_toggle_btn = "3" #Y button # Volume controls: mute, volume up and down input_audio_mute_axis = "+1" #Down on D pad/Left Stick input_volume_up_axis = "-3" #Up on Right Stick input_volume_down_axis = "+3" #Down on Right Stick # Take screenshot input_screenshot = "7" #Right Trigger button

Determining Button Values

No problem dude, glad to help.

@Electromaster64

I am trying to get rid of the start+select=exit hotkey

So do you want to disable the "Hotkey" function all together?

input_exit_emulator_btn = 8

And you want it to exit the RetroArch emulator when you press button #8 on your generic USB controllers?

I think you have to set the hotkey to null so try added this to your retroarch.cfg

input_enable_hotkey_btn = "nul"

If that doesn't work also add this:

input_enable_hotkey = "nul"

@dankcushions said in Two shader directories in 4.1?:

@batesman said in Two shader directories in 4.1?:

@dankcushions So is it possible to be able to cycle through the shaders without setting one as a default?

i think so. by default you need to hold your hotkey (select on your control pad) and press n or m on a keyboard, i believe.

You got it. I had to hold select on the control pad, then press m, n to cycle. Based on the way the hotkeys were defined in the retroarch.cfg file I thought I only needed to press m or n.

Thanks!

I wasn't able to map the hotkeys on the keyboard which is configured as a controller, but since I will use pyAutoGUI and scripting for GPIO inputs, I that's not a big deal.

The keycodes found in mupen64plus.cfg relate to ascii characters, and so I remapped the functions I plan to access later via GPIO to keys I won't need.

Here is simple overview I used to figure out key-values: Ascii Table
You have to look for the decimal values.

@tcmt which config ? Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first (You don't provide which version of retropie for example which affects the path im about to give you)

you should edit /opt/retropie/configs/all/retroarch/autoconfig/YOURJOYPAD.cfg and change the hotkey button in there.

@Ikyrus You could use something like jslisten to monitor for inputs, and invoke a script to switch config files.

https://github.com/workinghard/jslisten

@Yamt short answer no - you will have to remap it to another button (for that particular emulator/game).

No probs mate. Glad we got it sorted for you.

@Afgin

Never mind.

Problem has miraculously disappeared. Don't know what I have done differently, but seems to work now :D

partially resolved. i had a setting enabled that was preventing new games from coming in via the scrape options.

I see the problem.

The problem is you have enabled ParseGamelistOnly - which will mean it doesn't scan for roms and only shows items from scraped gamelists. Hence your roms are not showing up.

https://github.com/retropie/retropie-setup/wiki/FAQ

Parse Gamelists Only: If on, it will only read the roms you have scraped, so if you add any new roms it will not look for them unless you turn this back off. it is off by default.
also - are you aware any es_systems.cfg in /home/pi/.emulationstation will override the retropie-setup generated /etc/emulationstation/es_systems.cfg - you probably dont want that unless you are happy to maintain it manually.

Resolved the roms not appear.

I'm still dealing with being unable to set hotkeys on the controller.

Thank you for your help.
