Mapping certain keys from Atari800 emu to the gamepad

mediamogul · 10 Nov 2016, 14:44

There were a few small formatting errors that I corrected below:

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/by-id/3 \

	--axismap -Y1=Y1,-Y2=Y2 \

I suspect that evdev /dev/input/by-id/3 is also incorrect. When you run ls /dev/input/by-id/ from the command line, does your controller fully identify as "3"? If so, then you're fine, but I would think there is more to the name than that.

then, how do I paste this and where exactly?

Seeing as this is specific to Atari800, you'll want to use one of the two emulator-specific options noted in the guide that will run only alongside the emulator. Since you are just learning these things, I would recommend simply adding the command to /opt/retropie/configs/atari800/emulators.cfg, but just remember to make a backup when you're done, as this file gets overwritten after every update. Once added, it should look like:

atari800 = "sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/by-id/3 \
	--silent \
	--axismap -Y1=Y1,-Y2=Y2 \

	--detach-kernel-driver \
	--force-feedback \

	--deadzone 4000 \
	--mimic-xpad \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_X=x2,ABS_Y=y2,ABS_*=lt,ABS_*=rt,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \

@mediamogul
When I run "cat /proc/bus/input/devices" this is what I get for my PS3 pad:

Whan I run "ls /dev/input/by-id/" I get this:

So I'm a little confused on what shoudl I put in the --evdev /dev/input/by-id/* \ line :/

mediamogul · 11 Nov 2016, 03:43

@mahcneto

You're looking for the joystick event, so in your case, it would be:

--evdev /dev/input/by-id/usb-SZMY-POWER_CO._LTD._GAMEPAD_3_TURBO-event-joystick

mahcneto · 11 Nov 2016, 04:14

@mediamogul Ok! so i finally managed to put these lines in the atari800 emulators.cfg, now do I have to enable the xboxdrv to make the changes count?
EDIT: I did enable the xboxdrv but now all of my buttons are the joystick trigger and I'm still moving with the analog stick and not the Dpad. Tried the LT+Start to see if I get the emulator menu but doesn't work.

mediamogul · 11 Nov 2016, 05:59

@mahcneto

There might be something wrong with the mapping that isn't immediately visible. Try running the command by itself from a terminal window to see if it throws up any errors:

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/by-id/usb-SZMY-POWER_CO._LTD._GAMEPAD_3_TURBO-event-joystick \

mahcneto · 11 Dec 2016, 04:45

@mediamogul just did it and it says:

-- [ ERROR ] ------------------------------------------------------
error: invalid argument '--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_X=x2,ABS_Y=y2,ABS_=lt,ABS_=rt,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y'
couldn't convert 'ABS_*' to enum, not a member of EV_ABS

mediamogul · 11 Dec 2016, 08:56

@mahcneto

Ah, OK. Looks like you left in the place holder asterisks for 'lt' and 'rt' on the --evdev-absmap line. Just replace them with the event codes from your controller. After that, run the command again to see if any other errors pop up.

mahcneto · 11 Dec 2016, 16:37

@mediamogul pasted it correcting the *'s, and I got this:

Then I pasted & saved the same imput mapping in the atari800 emulators.cfg

default = "atari800"

After this I enabled the xboxdrv, performed a reboot and tested the Atari800 emu, and i'm still moving my characters with the analog stick, what am I missing?

mediamogul · 11 Dec 2016, 18:15

@mahcneto

There looks to be a couple of issues here and there. Try this:

atari800 = "sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/by-id/usb-SZMY-POWER_CO._LTD._GAMEPAD_3_TURBO-event-joystick \

Edit: Also, when pasting code into the forum, surrounding it in three backticks ``` on both sides helps to keep things manageable.

mahcneto · 12 Nov 2016, 18:43

Still doesn't work. Every single button works as the Atari Joystick trigger button, even start and select, dunno what to do :/

mediamogul · 12 Nov 2016, 19:51

@mahcneto

I suppose it could be in how the command is formatted. Below is the same command on one line, without any separation.

atari800 = "sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv --evdev /dev/input/by-id/usb-SZMY-POWER_CO._LTD._GAMEPAD_3_TURBO-event-joystick --silent --axismap -Y1=Y1,-Y2=Y2 --buttonmap tl^toggle=tl --buttonmap tr^toggle=tr --detach-kernel-driver --force-feedback --deadzone-trigger 15% --deadzone 4000 --mimic-xpad --evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_X=x2,ABS_Y=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y --evdev-keymap BTN_EAST=a,BTN_C=b,BTN_SOUTH=x,BTN_NORTH=y,BTN_WEST=lb,BTN_Z=rb,BTN_TL=tl,BTN_TR=tr,BTN_MODE=guide,BTN_TL2=back,BTN_TR2=start --ui-axismap X1=KEY_KP4:KEY_KP6,Y1=KEY_KP8:KEY_KP5 --ui-axismap X2=KEY_1:KEY_2,Y2=KEY_3:KEY_4,lt+X2=KEY_5:KEY_6,lt+Y2=KEY_7:KEY_8,rt+X2=KEY_9:KEY_0,rt+Y2=KEY_KPASTERISK:KEY_EQUAL --ui-buttonmap a=KEY_RIGHTCTRL,b=KEY_F2,x=KEY_EQUAL,y=KEY_KPASTERISK,lb=KEY_F9,rb=KEY_F5,du=KEY_KP8,dd=KEY_KP5,dl=KEY_KP4,dr=KEY_KP6,start=KEY_F4,back=KEY_F3,lt=KEY_HOME,rt=KEY_HOME,tl=KEY_HOME,tr=KEY_HOME --ui-buttonmap lt+a=KEY_ENTER,lt+b=KEY_ESC,lt+du=KEY_UP,lt+dd=KEY_DOWN,lt+dl=KEY_LEFT,lt+dr=KEY_RIGHT,lt+start=KEY_F1 --ui-axismap lt+X1=KEY_LEFT:KEY_RIGHT,lt+Y1=KEY_UP:KEY_DOWN --ui-axismap tl+x1=REL_X:10,tl+y1=REL_Y:10 --ui-buttonmap tr+b=BTN_LEFT,tr+a=BTN_RIGHT --ui-buttonmap guide=void -- /opt/retropie/emulators/atari800/bin/atari800 %ROM%"

Hubz · 11 Mar 2017, 19:52

I managed to get your config to work, what a godsend! Thank you! The only problem I have is my Wii U Pro Controller maps the RThumb (R3) and LThumb (L3) as btn instead of abs. Is there anyway to use your setup for Super Breakout etc.? After toggling I get no response from the thumbsticks and I'm guessing it is due to them being buttons instead of axis.

mediamogul · 11 Mar 2017, 20:17

@Hubz

That's tough to say. It's such a specialty situation that anything I say would be guesswork. Did the controller require a driver or did it just pair with Bluetooth?

Hubz · 16 Mar 2017, 22:46

It paired with bluetooth, I may just have to use a different controller. Not the end of the world. Odd how it maps though!

dunnieboy · 26 Apr 2017, 21:32

meant for another thread.

gmorker · 21 Apr 2021, 23:01

@mahcneto said in Mapping certain keys from Atari800 emu to the gamepad:

emus, is there any way to map certain keys to the gamepad since this console uses just 1 button for playing? These ones mostly:

This is a very old thread but I want to share somenthing that works well for me just in case someone else will find it useful.

I purchased a $16 3-Key USB keypad from amazon https://www.amazon.com/dp/B08P1GY3GN/ref=cm_sw_em_r_mt_dp_H610W0ZBZ6DNXZSZESYK

I easily (30 second effort) programed the keys to F2, F3, F4 and it works perfectly!
