Guide: Advanced Controller Mappings

@mediamogul Hi. I'm having a few problems with ScummVM and mapping my joystick 1 to operate like a mouse.

I have a bluetooth keyboard which has a built in touchpad and I can use that to navigate in game perfectly. My joystick 2 is also natively working as a joystick, albeit the axes are mixed up.

I've followed the guide, but I think I've got myself confused. This is the first time I've tried to mimic a mouse.

Do I need to start from scratch and determine what event number is the keyboard/touchpad and go from there (using cat /proc/bus/input/devices)?

So far I have:

Player1_ScummVM="sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv > /dev/null 2>&1 \
--silent \
--detach-kernel-driver \
--deadzone=4000 \
--deadzone-trigger 15% \
--force-feedback \
--mimic-xpad \
--trigger-as-button \
--ui-buttonmap x=void,y=void,lb=void,rb=void,tl=void,tr=void,guide=void,lt=void \
--evdev /dev/input/by-path/platform-3f980000.usb-usb-0:1.3.3:1.0-event-joystick \
--device-name "Player_1" \
--evdev-absmap ABS_X=y1,ABS_Y=x1 \
--evdev-keymap BTN_THUMB2=a,BTN_PINKIE=b,BTN_TRIGGER=x,BTN_THUMB=y,BTN_TOP2=lb,BTN_TOP=rb,BTN_BASE3=back,BTN_BASE6=start,BTN_BASE2=lt,BTN_BASE5=rt \
--axismap -Y1=Y1,-Y2=Y2 \
--ui-axismap X1=REL_X:10,Y1=REL_Y:10 \
--ui-buttonmap a=BTN_LEFT,b=BTN_RIGHT,back=KEY_UNKNOWN,start=KEY_UNKNOWN,rt=KEY_F5,back+rt=KEY_LEFTALT+KEY_X"

And


	scummvm)
		$xboxkill
		joycommand="$clear & $Player1_ScummVM & $silence &"
		eval $joycommand
	;

This code doesn't work at all at present. Thanks for any help you can provide.

@spud11

Does xboxdrv throw up any errors? At some point I changed the guide to suggest redirecting all errors to the Runcommand log rather than /dev/null. That might be helpful here. Just replace:

> /dev/null 2>&1

with

>> /dev/shm/runcommand.log 2>&1

As long as you have an otherwise working xboxdrv command, the following two lines should be all that's required to add full mouse control to whatever the first axis is on the controller you're trying to map, with buttons 'A' and 'B' acting as left/right click..

--ui-axismap X1=REL_X:10,Y1=REL_Y:10 \
--ui-buttonmap a=BTN_LEFT,b=BTN_RIGHT

spud11

@mediamogul Thanks. You were 100% right. I found an error - just a missing ; which I've added back in. Thanks again.

mediamogul

@spud11

Not a problem.

I don't see you mention a command to killall xboxdrv in the runcommand-onend script. If it is in fact there, make sure you're using sudo

I changed the logic to use xboxdrv for all games in "Arcade" - some with 4-way restriction and some without. It is launched by runcommand-onstart and killed by runcommand-onend. I do use sudo. The issue that I am still having is that (and I am not sure what the sequence is to reproduce,) the order of joysticks changes: first few times, when a game starts I see the yellow text on the bottom of the screen showing the mapped controllers and the Controlblock joystics map to #0 and #1 and xbox to #2 and #3. Then at some point, xboxdrv maps to #0 and #1 and Controlblock to #2 and #3 and the game does not respond (because the arcade folder retroarch.cfg maps 2 and 3 to player 1 and 2 and the Controlblock joystick is not active anymore.)

You might also try looking at /dev/input/by-path/.

It does not show my Controlblock joysticks, just like /dev/input/by-id/

mediamogul

@guydot

Have you updated RetroArch in a while? This may not be the issue, but recently a fix was implemented to avoid controller ordering based on detection. Before hand this was messing with tools like joystick selection utility. If you haven't already, try updating and see if the behavior continues.

@guydot

I did a Retroarch update but it did not solve the issue. I am running RPi3 B+/Stretch/RetroPie 4.4, so it is a very recent image.

At some point, Retroarch (yellow text on bottom just before the game starts) shows an incorrect port joystick mapping and the game does not work. Killing xboxdrive restores the use of Controlblock to exit the game, but Retroarch would not get the right mapping if I launch a new game unless I reboot. Frustrating.

mediamogul

@guydot

This may be able to be sorted out as-is, but if you're open to an alternative, let me suggest something more reliable. I avoid the uncertainty of these particular situations by having a keyboard map set for players one and two in RetroArch. To correspond with this, I also have my two controllers fully key-mapped with xboxdrv to match. Once everything is launched, it really doesn't matter which controller RetroArch tries to grab hold of, because it'll be acknowledging the keyboard map regardless.

spud11

@mediamogul @guydot I agree 100% with this approach. Mediamogul put me onto this method about 2 years ago and it just works. 99% of cores and emulators have keyboard mapping. I've only struggled with one or two eg reicast; otherwise, all good.

guydot

@mediamogul I will give it a shot, as all other methods failed. The closest I got was with Joystick Selection "by name" method: the games work well even when Retroarch shuffled the ports, but Emulationstation crashes when I exit a "port-confused" game.

If I understand the method correctly - I will have to change Controlblock to "MAME" mode = keyboard emulation and then run 2 xboxdrv configured to match the keys generated by my controllers. Correct?

Actually, you would just change your xboxdrv maps to be complete key-mappings of the Controlblock. From there, you'd assign those keys to players one and two in RetroArch.

guydot

@mediamogul @spud11 I am missing something here.

Right now:
(1) Controlbox is creating 2 joypads: JS0/JS1 and event 2/3
(2) I use 2 xboxdrv commands, each has --evdev-absmap and --evdev-keymap that correspond to a joypad joystick + buttons
(3) In Retroarch.cfg, I tried to use input_player1_joypad_index = "2" and input_player2_joypad_index = "3" to map

Is proposed method to add --ui-buttonmap to map xboxdrv to keyboard keys? I guess I need more steps... Thanks for all your help!

mediamogul

@guydot said in Guide: Advanced Controller Mappings:

It is, yes. As an example, below is an excerpt from my retroarch.cfg file where I've mapped my desired keyboard inputs for player one. Below that is a 4-way strict xboxdrv map that corresponds to those keys.

retroarch.cfg excerpt:

# Keyboard input, Joypad and Joyaxis will all obey the "nul" bind, which disables the bind completely, 
# rather than relying on a default.
input_player1_a = "a"
input_player1_b = "b"
input_player1_y = "y"
input_player1_x = "x"
input_player1_start = "t"
input_player1_select = "e"
input_player1_l = "l"
input_player1_r = "r"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"
input_player1_l2 = "d"
input_player1_r2 = "f"
input_player1_l3 = "c"
input_player1_r3 = "v"

4-way strict xboxdrv command:

Not a problem. Let us know how it works out.

@mediamogul - Post 534...action...wow long thread! ;) I was wondering if I could get your help with setting up XBOX 360 controllers if possible, please, when/if you have time. I am in no hurry but not quite sure what to do next once I get the controllers setup.

I have four XBOX 360 controllers using a wireless dongle. I use the Arcade folder running mame2003, FBA and Advmame for about 300 games. Basically I just want to break down the games for 4/8-way restriction. Good 4-way games are lost to simple mistakes of not hitting that ladder squarely in Donkey Kong, etc. using controllers.

I am running RP 4.3 on a Pi 3 updated to the latest RetroPie script as of yesterday. My cores are recent from source and Advmame is on 3.8.

I went through the tutorial and here's what I ended up with but I had a few questions. For calibration axis name. Do I use the output from evtest /dev/input/event[event1] and add it 3 times as shown below?

evtest output for 360 controller:

A = BTN_SOUTH = 304
B = BTN_EAST = 305
X = BTN_NORTH = 307
Y = BTN_WEST = 308
LB = BTN_TL = 310
RB = BTN_TR = 311
LT = BTN_TL2 = 312
RT = BTN_TR2 = 313
BACK = BTN_SELECT = 314
START = BTN_START = 315
GUIDE = BTN_MODE = 316
TL = BTN_THUMBL = 317
TR = BTN_THUMBR = 318
X1/Y1 = ABS_X (UP/DOWN) | ABS_Y (LEFT/RIGHT)
X2/Y2 = ABS_RX (UP/DOWN) | ABS_RY (LEFT/RIGHT)
DPAD_Y/DPAD_X = ABS_HAT0Y (UP/DOWN) | ABS_HAT0X (LEFT/RIGHT)

Also with a 360 controller I didn't get output for rt/lt or at least I assigned them to buttons TL2 & TR2 as they aren't an axis? So I have two fields below still using asterisks.

Lastly should I use the option to make the triggers into buttons on a 360 controller. I added the option below.

Lastly, lastly do I need to use the rename parameter for each controller as I have 4 but they are all the same. Well they are 2 different models among the 4 but they are all detected as the same. Do I need to define 4 controllers in the rc.local file?

If I get this first step implemented correctly is there a guide restricting games to 4/8 way? Disclosure I didn't read all 533 posts so if there's a relevant section I can read through or a link to what steps I should think about next. Thanks Media for all this information, it's pretty incredible stuff. I wish 4/8 restriction was a controller feature as it's kind of relevant-ish to good gaming.

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/by-id/[usb-Â©Microsoft_Xbox_360_Wireless_Receiver_for_Windows_E0C26450-event-joystick] \
	--silent \
	--detach-kernel-driver \
	--force-feedback \
	--deadzone-trigger 15% \
	--deadzone 4000 \
	--calibration X=-32767:0:32767,Y=-32767:0:32767 \
	--calibration RX=-32767:0:32767,RY=-32767:0:32767 \
	--calibration HAT0Y=-32767:0:32767,HAT0X=-32767:0:32767 \
	--trigger-as-button \
	--mimic-xpad \
	--evdev-absmap ABS_[X]=x1,ABS_[Y]=y1,ABS_[RX]=x2,ABS_[RY]=y2,ABS_[•]=lt,ABS_[•]=rt,ABS_[HAT0Y]=dpad_x,ABS_[HAT0X]=dpad_y \
	--evdev-keymap BTN_[SOUTH]=a,BTN_[EAST]=b,BTN_[NORTH]=x,BTN_[WEST]=y,BTN_[TL]=lb,BTN_[TR]=rb,BTN_[TL2]=tl,BTN_[TR2]=tr,BTN_[MODE]=guide,BTN_[SELECT]=back,BTN_[START]=start \

Also something odd is it seems the X/Y axis is "inverted" on the d-pad vs. the left/right stick on a 360 controller using evtest /dev/input/event[event1] so in the script above I have HAT0Y as X and HAT0X as Y.

@Riverstorm

Good 4-way games are lost to simple mistakes of not hitting that ladder squarely in Donkey Kong, etc. using controllers.

I hear you. Correcting that issue is probably my favorite use of all this stuff.

Do I use the output from evtest /dev/input/event[event1] and add it 3 times as shown below?

Seeing as how you have two different models, I'd at least confirm that they're all identifying the same way. When mapped, xboxdrv will delineate them from the --evdev location you enter. I assume that there are four unique entries at /dev/input/by-id/?

Also with a 360 controller I didn't get output for rt/lt or at least I assigned them to buttons TL2 & TR2 as they aren't an axis?

Based on your listing, they appear to be buttons, as BTN_ denotes buttons and ABS_ denotes an axis.

Lastly should I use the option to make the triggers into buttons on a 360 controller. I added the option below.

That's what I do and mine are definitely buttons already. If I'm remembering correctly, it adds a bit of flexibility for using them as hotkeys if need be.

Lastly, lastly do I need to use the rename parameter for each controller as I have 4 but they are all the same.

I would, yes. It helps certain software delineate the controllers and it really helps visually when you're trying to identify them yourself.

Also something odd is it seems the X/Y axis is "inverted" on the d-pad vs. the left/right stick

This seems to be normal behavior with all controllers for some reason. Our approaches may differ, but below, you'll see I used --axismap -Y1=Y1,-Y2=Y2 to correct the issue on mine. The example is a base command I use for 4-way restriction with no other fancy additions, so it should also answer your question about the restriction method itself. All that ever needs to be added to any command is --four-way-restrictor to make it happen. However, you can also restrict the DPad with --modifier dpad-restrictor=fourway. It's arguably unnecessary due to most DPads being restricted by design, but I usually add it anyway for good measure.

Below that I'll post a listing of all the arcade ROMs that I currently 4-way restrict. Over time, I've actually started doing this for similar games on most older console platforms as well. It really pays off more often than you'd think.

Ah, I almost forgot to give an example of how you would handle this ROM-specifically from the runcommand-onstart. There are quite a few ways actually, but this is probably the easiest to illustrate and it uses the xboxdrv launch command I posted above. You'll notice I only used three games, but you can add as many as you want accordingly.

@mediamogul - Thank you for the help and information. I am going to give it a shot and will let you know how it turns out. I have a few more questions but you've given me plenty here to get started, thank you good sir and have a great weekend.

On a side note, are from the Carolina's? I have no idea why I keep thinking you are from that area and I was thinking of you during the weekend of that devastating hurricane. If I remember you were doing yard work in like April with some nice weather and we got hammered here for one of the biggest snows on record that month. I almost posted a pic for you to check it out. ;)
