[SOLVED] Hotkeys configuration : Switch the shaders ingame (Retropie v.3b4)

[kommissar]

Hi everyone,

After digging the net for weeks, i didn’t find the answer to my issue.
I can’t set the hotkeys for switching the shaders ingame (previous/next shaders) in Retropie v.3b4 (rpi2).
I successfully set these hotkeys in the Retropie v.3 (rpi1) and v.2.6 (rpi1).
I just bought a Raspberry Pi 2, so i wanted to put the correct system version on my new Pi.

This is my current config for my controller (iBuffalo Snes controller) :

# ======================================================================
# Config : iBuffalo SNES Classic Gamepad : Par défaut
# ======================================================================
input_a_btn = "0"
input_b_btn = "1"
input_x_btn = "2"
input_y_btn = "3"
input_start_btn = "7"
input_select_btn = "6"
input_l_btn = "4"
input_r_btn = "5"
input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"

# ======================================================================
# Config : iBuffalo SNES Classic Gamepad : Hotkeys
# [Select] + [Start]      : Leave the game
# [Select] + [R]          : Save state
# [Select] + [L]          : Load state
# [Select] + [B]          : Reset
# [Select] + [DPad-LEFT]  : Previous shader
# [Select] + [DPad-RIGHT] : Next shader
# [Select] + [DPad-DOWN]  : Decrease state slot
# [Select] + [DPad-UP]    : Increase state slot
# ======================================================================
input_enable_hotkey_btn = "6"
input_exit_emulator_btn = "7"
input_save_state_btn = "5"
input_load_state_btn = "4"
input_reset_btn = "1"
input_shader_prev_axis = "-0"
input_shader_next_axis = "+0"
input_state_slot_increase_axis = "-1"
input_state_slot_decrease_axis = "+1"

This config works for the rpi1 version, but not the rpi2.
I also tried with the “btn” version of the hotkey on Y and X (input_shader_prev_btn). Same result. :/
Did i miss something ?

PS : Sorry for my english. It’s not my native language. ^^

EDIT : 2015-07-14

Solution : Update RetroArch
In emulationstation : go to Retropie > RETROPIE-SETUP
Then : choose “5 Install individual emulators from binaries or source”
Find retroarch > binary
Reboot
And it works :D

Big thanks to buzz for the solution !!!

I know you’ve said you are using version 3 beta 4, but can you confirm the full path of the file you are showing above?

[kommissar]

Of course. It’s the controller configuration file located here :
/opt/retropie/configs/all/retroarch-joypads/USB,2-axis8-buttongamepad.cfg

I forgot to precise : when i use the hotkey (SELECT + “left” or “right”), i leave the emulator. Unfortunately, i don’t see any log error message on the screen.

[Floob]

Can you put on pastebin.com your file
/opt/retropie/configs/all/retroarch.cfg?

Also, I’m presuming you havent altered any system specific retroarch.cfg files.

[kommissar]

Here, the link to the files :
/opt/retropie/configs/all/retroarch-joypads/USB,2-axis8-buttongamepad.cfg

/opt/retropie/configs/all/retroarch.cfg

I didn’t change anything in the /all/retroarch.cfg. But in /mastersystem/retroarch.cfg, i just did these changes :

#video_shader = /opt/retropie/emulators/retroarch/shader/phosphor.glslp
video_shader_enable = true

I enable the shaders changes and comment the default used shader.

EDIT : After a purge of /tmp : I got a log !!!

/opt/retropie/supplementary/runcommand/runcommand.sh: line 671:  3983 Segmentation fault      /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-picodrive/picodrive_libretro.so --config /opt/retropie/configs/mastersystem/retroarch.cfg "/home/pi/RetroPie/roms/mastersystem/Mortal Kombat (UE) [!].sms" --appendconfig /tmp/retroarch.cfg

It seems something wrong occurred during the command execution. I checked all the paths used in the command are correct / exists. (with ls -al <path>)

[Floob]

Try changing
input_enable_hotkey = nul
to
input_enable_hotkey = alt

in your
/opt/retropie/configs/all/retroarch.cfg

Then in game, hold “select” and check “m” and “n” work to change shader.

[kommissar]

I tried it. The behavior is the same : exit to emulationstation.
Same error in the log too : runcommand.sh line 671: 3034 Segmentation fault
:/

[Floob]

Can you try from a clean retropie 3 beta 4, then just add
input_shader_prev_axis = “-0”
input_shader_next_axis = “+0”

to the controller file it generates?

[kommissar]

Well, i just tried on a fresh install of Retropie v.3b4 and … the behavior is the same : runcommand.sh line 671: 3034 Segmentation fault.
The steps i did for this install :
* Write the image on SD card
* Detect my pad with emulationstation (/opt/retropie/configs/all/retroarch-joypads/USB,2-axis_8-button_gamepad__.cfg generated)
* Add “Alex kidd in Miracle World” (all my childhood :D) in mastersystem roms directory.
* Edit the retroarch.cfg in mastersystem in order to enable shaders (with and without the 1st line):

video_shader = /opt/retropie/emulators/retroarch/shader/phosphor.glslp
video_shader_enable = true

* Edit USB,2-axis_8-button_gamepad__.cfg : i tested 2 configs :

/* other buttons... */
input_shader_prev_axis = "-1"
input_shader_next_axis = "+1"
input_enable_hotkey_btn = "6"

and

/* other buttons... */
input_enable_hotkey_btn = "6"
input_shader_prev_axis = "-1"
input_shader_next_axis = "+1"

I swapped +/-0 and +/-1, same result on the respective shader assign button.

The complete log file : /tmp/runcommand.log

I just gave this a go and I get the same results.
Its fine in RetroPie 3 beta 2.

My log file was

I’ll raise an issue on Github.

[kommissar]

Ok, thanks to confirm that it was a bug. I started to being mad by installing again & again images on SD, checking all the config files in order to find my mistake.
You saved my mental health. :D

[petrockblog]

update retroarch from binary via menu 5 in retropie-setup. there are multiple retroarch bugs in the last image which have been solved since.

[kommissar]

Thanks !!!! It works perfectly now !!!!

Hi guys – pretty new to RetroArch/Pie. Struggling with a few things and this is one of them! Latest version of RetroPie from the site.

My /opt/retropie/configs/all/retroarch-joypads/

input_device = "raphnet.net (S)NES/Atari_USB"
input_driver = "udev"
input_l2_btn = "6"
input_start_btn = "3"
input_exit_emulator_btn = "3"
input_up_axis = "-1"
input_a_btn = "4"
input_b_btn = "0"
input_reset_btn = "0"
input_down_axis = "+1"
input_r2_btn = "7"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_x_btn = "5"
input_menu_toggle_btn = "5"
input_select_btn = "2"
input_enable_hotkey_btn = "2"
input_y_btn = "1"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

# ======================================================================

input_save_state_btn = "7"
input_load_state_btn = "6"
input_reset_btn = "1"
input_shader_prev_axis = "-1"
input_shader_next_axis = "+1"

I have applied a single shader and it works…. but i cannot get the shader switching to work.

Also the STATE Hotkeys work – but not the Shaders

Any ideas?

PS I have updated the binary as well.

[nemo1966]

Seems to be broken – RetroPie seems to be getting more and more abstracted and less seems to work. :-(

[mydriaze]

Any update on this? I can’t cycle through the shader neither. Xboxcontroller config file seems ok, but nothing is working.

By the way, I just plugged in keyboard, but the “m” and “n” key are not working. Can someone confirm if it’s working or not at the moment with the last build?
