Guide: Advanced Controller Mappings

mediamogul · 2 Jul 2017, 15:32

I use a trick to where I put --evdev-no-grab into an xboxdrv configuration. This allows the physical controller to still have control input that would otherwise be blocked to prevent a conflict with the xboxdrv virtual controller. Then I map every button on the virtual controller to KEY_UNKNOWN except for the right joystick, which I map to the number pad. This way, RetroArch can still make use of the original control scheme with only the right joystick being read as keyboard input.

@mediamogul

so cool

i will give that a shot and see what i come up with
thanks again

ExarKunIv · 7 Feb 2017, 21:56

here is what i got for now.

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
    --evdev /dev/input/event2 \
    --silent \
	--detach-kernel-driver \
	--force-feedback \
	--mimic-xpad \
	--dpad-as-button \
        --deadzone 15% \
	--trigger-as-button \
	--evdev-no-grab \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \
	--evdev-keymap KEY_#304=a,KEY_#305=b,KEY_#307=x,KEY_#308=y,KEY_#312=lt,KEY_#313=rt,KEY_#310=lb,KEY_#311=rb,KEY_#317=tl,KEY_#318=tr,KEY_#314=back,KEY_#315=start \
	--axismap -Y1=Y1,-Y2=Y2 \
        --ui-buttonmap a=KEY_UNKNOWN,b=KEY_UNKNOWN,start=KEY_UNKNOWN,back=KEY_UNKNOWN,x=KEY_UNKNOWN,y=KEY_UNKNOWN,lt=KEY_UNKNOWN,rt=KEY_UNKNOWN,lb=KEY_UNKNOWN,rb=KEY_UNKNOWN,tl=KEY_UNKNOWN,tr=KEY_UNKNOWN \
	--ui-axismap x2=KEY_1:KEY_2,Y2=KEY_3:KEY_4 \
&

i dont get any errors, but still no mapping.
the no-grab works. as my left stick works fine. i think im useing the no-grab wrong
i'll mess around with it more tomrrow.

@ExarKunIv

RetroArch may be prioritizing the virtual xboxdrv controller as player one.

ExarKunIv · 8 Feb 2017, 16:51

@mediamogul

so i need to use this im guessing?


input_remapping_directory = "/opt/retropie/configs/fba/"

input_player1_joypad_index = "1"
input_player2_joypad_index = "0"
input_player2_analog_dpad_mode = 1

#include "/opt/retropie/configs/all/retroarch.cfg"

sorry for asking all the questions. this config stuff for me is very confusing

mediamogul · 2 Aug 2017, 17:44

@ExarKunIv

Not a problem. If it is that RetroArch is confusing the controller order and if we're still talking about videopac/Odyssey², then your additions are right, but they should be made in /opt/retropie/configs/videopac/retroarch.cfg which would in turn mean that the first line would be:

input_remapping_directory = "/opt/retropie/configs/videopac/"

ExarKunIv · 8 Feb 2017, 17:44

@mediamogul

ok cool

i will give that a shot and see if i get anything to build on

ExarKunIv · 8 Feb 2017, 18:23

i think this looks right from what you said

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line


input_device = "Xbox 360 Wireless Receiver (XBOX)"
input_driver = "udev"
input_r_y_plus_axis = "+4"
input_l3_btn = "9"
input_r_x_minus_axis = "-3"
input_l_btn = "4"
input_load_state_btn = "4"
input_start_btn = "7"
input_exit_emulator_btn = "7"

input_a_btn = "1"
input_b_btn = "0"
input_reset_btn = "0"

input_remapping_directory = "/opt/retropie/configs/videopac/"

input_player1_joypad_index = "1"
input_player2_joypad_index = "0"
input_player2_analog_dpad_mode = 1

#include "/opt/retropie/configs/all/retroarch.cfg"

ExarKunIv · 8 Feb 2017, 19:51

ok this is a good head turner

i add this to my videopac as we said

input_remapping_directory = "/opt/retropie/configs/videopac/"

input_player1_joypad_index = "1"
input_player2_joypad_index = "0"
input_player2_analog_dpad_mode = 1

#include "/opt/retropie/configs/all/retroarch.cfg"

and it switchs my 8BitDo to player 2

if i change it to this

input_remapping_directory = "/opt/retropie/configs/videopac/"

input_player1_joypad_index = "0"
input_player2_joypad_index = "1"
input_player2_analog_dpad_mode = 1

#include "/opt/retropie/configs/all/retroarch.cfg"

its player 1 again

and here is what i got when i ran the script

Your Xbox/Xbox360 controller should now be available as:
  /dev/input/js1
  /dev/input/event3

Press Ctrl-C to quit
Shutdown complete

not really sure where to go from here.

mediamogul · 8 Feb 2017, 20:33

@ExarKunIv

That appears to indicate a successful launch of xboxdrv. Are you saying that it stays on that screen indefinitely? Post your script and we'll take a look.

ExarKunIv · 8 Feb 2017, 21:30

@mediamogul

it says up until i exit a game, turn off my controller, or press ctrl c

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
    --evdev /dev/input/event2 \
    --silent \
	--detach-kernel-driver \
	--force-feedback \
	--mimic-xpad \
        --deadzone 15% \
	--evdev-no-grab \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \
	--evdev-keymap KEY_#304=a,KEY_#305=b,KEY_#307=x,KEY_#308=y,KEY_#312=lt,KEY_#313=rt,KEY_#310=lb,KEY_#311=rb,KEY_#317=tl,KEY_#318=tr,KEY_#314=back,KEY_#315=start \
	--axismap -Y1=Y1,-Y2=Y2 \
        --ui-buttonmap a=KEY_UNKNOWN,b=KEY_UNKNOWN,start=KEY_UNKNOWN,back=KEY_UNKNOWN,x=KEY_UNKNOWN,y=KEY_UNKNOWN,lt=KEY_UNKNOWN,rt=KEY_UNKNOWN,lb=KEY_UNKNOWN,rb=KEY_UNKNOWN,tl=KEY_UNKNOWN,tr=KEY_UNKNOWN \
	--ui-axismap x2=KEY_1:KEY_2,Y2=KEY_3:KEY_4 \
&

is that i manually add

the shutdown complete was just from me exiting the game.
other then no errors coming up i get no mapping down. i still need my usb keyboard in to press 1

mediamogul · 8 Feb 2017, 22:07

@ExarKunIv

I've only ever known the screen to stay like that when the '&' is left off the tail end of the xboxdrv launch script. If that were the case, pressing 'Ctrl-C' would stop xboxdrv and allow things to move forward without the map being active, which would explain why it's not accessible once the emulator is up. You've posted the command itself, but can you post it in context with how it's being launched from runcommand-onstart.sh?

ExarKunIv · 9 Feb 2017, 15:27

@mediamogul

if [ "$1" = "Videopac" ]

sorry for the delay
busy nite

mediamogul · 9 Feb 2017, 16:07

@ExarKunIv

Everything appears to be OK. The only thing I can even guess is that there might be something else in runcommand-onstart.sh that may be conflicting in some way.

ExarKunIv · 9 Feb 2017, 18:41

@mediamogul

ok ill pull out the other configs and see that i get

ExarKunIv · 9 Feb 2017, 20:07

ok i pulled everything out of my runcommand-onstart.sh

and still got nothing. so i ran cat /proc/bus/input/devices
and got this

cat /proc/bus/input/devices
I: Bus=0005 Vendor=3810 Product=0009 Version=0100
N: Name="8Bitdo FC30 Pro"
P: Phys=b8:27:eb:47:c7:78
S: Sysfs=/devices/platform/soc/3f201000.uart/tty/ttyAMA0/hci0/hci0:11/0005:3810:0009.0003/input/input8
U: Uniq=e4:17:d8:7a:6a:7d

B: PROP=0
B: EV=1b
B: KEY=ffff0000 0 0 0 0 0 0 0 0 0
B: ABS=30627
B: MSC=10

the event code is different. so i went in and changed it in my script

if [ "$1" = "Videopac" ]
then
sudo killall > /dev/null 2>&1 xboxdrv
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv > /dev/null 2>&1 \
    --evdev /dev/input/event0 \
    --silent \
	--detach-kernel-driver \
	--force-feedback \
	--mimic-xpad \
        --deadzone 15% \
	--evdev-no-grab \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \
	--evdev-keymap KEY_#304=a,KEY_#305=b,KEY_#307=x,KEY_#308=y,KEY_#312=lt,KEY_#313=rt,KEY_#310=lb,KEY_#311=rb,KEY_#317=tl,KEY_#318=tr,KEY_#314=back,KEY_#315=start \
	--axismap -Y1=Y1,-Y2=Y2 \
        --ui-buttonmap a=KEY_UNKNOWN,b=KEY_UNKNOWN,start=KEY_UNKNOWN,back=KEY_UNKNOWN,x=KEY_UNKNOWN,y=KEY_UNKNOWN,lt=KEY_UNKNOWN,rt=KEY_UNKNOWN,lb=KEY_UNKNOWN,rb=KEY_UNKNOWN,tl=KEY_UNKNOWN,tr=KEY_UNKNOWN \
	--ui-axismap x2=KEY_1:KEY_2,Y2=KEY_3:KEY_4 \
&
fi

sadly nothing, but i can test it my controller using evtest /dev/input/event0
and i get reading, but nothing showing any mapping. :(
so it still seems that the --evdev-no-grab \ is working too well

edit
i know why the event number changed so no big on there

ExarKunIv · 9 Feb 2017, 21:18

update

my mapping works, i move my right joystick and i get KEY_1, KEY_2 ect..and when i exit the evtest /dev/input/event1 goes away showing that it see that i have exited the same, and the --evdev-no-grab \ works as i can move with in the game just fine....as long as i have a usb keyboard to press 1 for me.

for some reason it will not see my mapping as a valid key press

now im confused.

mediamogul · 9 Feb 2017, 21:35

@ExarKunIv

for some reason it will not see my mapping as a valid key press

Ah, OK. I think I know what's wrong. Take a look at the final part of section 3A of the guide if you haven't already. It tells how to set a udev rule so that RetroArch will see the xboxdrv vitualized keyboard as being a real keyboard.

ExarKunIv · 9 Feb 2017, 22:16

@mediamogul

the funny thing is that i already had that, so when i looked at it again i saw my problem

you have this on your guide

SUBSYSTEM=="input", ATTRS{name}=="Microsoft X-Box 360 pad - Keyboard Emulation", GROUP="users", MODE="0666", ENV{ID_INPUT_KEYBOARD}="1"

i had to change it to this

SUBSYSTEM=="input", ATTRS{name}=="Microsoft X-Box 360 pad", GROUP="users", MODE="0666", ENV{ID_INPUT_KEYBOARD}="1"

i know that i dont have a custom name but i remember what the cat /proc/bus/input/devicespulled up when i ran it whit the script going.

so i think that did it, but i will have to do more testing tomorrow, but it is looking good now

and as always thanks for the help

mediamogul · 9 Feb 2017, 23:35

@ExarKunIv said in Guide: Advanced Controller Mappings:

you have this on your guide... i had to change it to this

I'll test that with a few controllers. It may need to be changed in the guide. Thanks for pointing it out.
