PS4 Analog Stick as Mouse for DosBox - Need Help

dunnieboy

Can someone point me to recent instructions on how to do this ... there seems to be a glut of WIP threads but I can find anything final.

Again - I'd like to use my wireless PS4 controller to use the left stick for moving the mouse cursor and the X button to left click and the circle button as right click. The arrows keys i'd like to map to the D-pad. Escape is mapped to share, Enter to options and space could be the big rectangular button or triangle.

Thanks for any help. - I'd pay for a video tutorial ! =)

@dunnieboy

The built-in DOSBox mapper is the easiest, most effective way to key-map like you're wanting. However, I don't think it will handle the mouse mapping. For that you'll need an external mapping solution. There's a guide here detailing how to accomplish this in xboxdrv, but it's a couple of streets over from being a video tutorial. If it's something you end up exploring and have questions, I'll be happy to help.

this tutorial does not work.

cd retropie/emulators/dosbox/bin/ does bring me into the bin directory, but when I enter the next command dosbox -startmapper I get -bash: dosbox: command not found.

@mediamogul This tutorial is awesome .. however i am running into one problem ... my ps4 wireless controller is giving off signal constantly due to the tilt sensitivity. Do you know a way to kill that ?

@dunnieboy

Not off hand, but you may be able to push a button on your controller, kill evtest immediately and then scroll up to see what the input was. You'd have to do that for each button, but I don't really know of another way.

@dunnieboy It's not possible to map the mouse to an analog stick using the DOSBox mapper. I use the Linux Joystick Mapper to map the mouse to the left analog stick of PS3 controller.

Here are some threads that describe how to set this up:

Thanks guys ... Amazing community here.

@dudleydes ok ... so I think I have everything setup correctly .. but when I enter command and conquer my keyboard is the only device being accessed (and its touchpad is being picked up as mouse)

I did the whole joymap thing and got it configured correctly I think.

I use .sh files to call .conf files to launch my DOS titles. Here is the code for both.

cc.sh
sudo /home/pi/joymap-0.4.2/loadmap /home/pi/RetroPie/roms/pc/dosbox-map/mouse.map &
/opt/retropie/emulators/dosbox/bin/dosbox -conf "/home/pi/RetroPie/roms/pc/CC.conf"

then in the [autoexec] portion of my cc.conf file I have this ...

[autoexec]
mount c /home/pi/RetroPie/roms/pc
c:
mount d /home/pi/RetroPie/roms/pc/CC_INSTALL/CDROM -t cdrom -usecd 0 -label GDI
cd c&c
c&C
exit

Here is my ps4 mouse.map

#General Mouse Mapping for DOSBox

Thoughts ?

@dunnieboy Your configs look fine.

It may be worth testing whether the loadmap binary is working. To do this, I created a file test.map with the following contents for a PS3 controller:

# Test Mapping

# D-Pad to letters
button vendor=0x054c product=0x0268 src=4 target=kbd button="a"
button vendor=0x054c product=0x0268 src=5 target=kbd button="b"
button vendor=0x054c product=0x0268 src=6 target=kbd button="c"
button vendor=0x054c product=0x0268 src=7 target=kbd button="d"

# Buttons to numbers
button vendor=0x054c product=0x0268 src=12 target=kbd button="num1"
button vendor=0x054c product=0x0268 src=13 target=kbd button="num2"
button vendor=0x054c product=0x0268 src=14 target=kbd button="num3"
button vendor=0x054c product=0x0268 src=15 target=kbd button="num4"

From the terminal on the Pi itself - this will not work if you run a terminal session via SSH, run the following command:

sudo /home/pi/joymap-0.4.2/loadmap /path/to/test.map

When I run this, I see the following messages confirming that loadmap has successfully mapped my PS3 controller:

0 joysticks.
Found device Sony PLAYSTATION(R)3 Controller (vendor=0x054c, product=0x0268)
Found device JOYMAP Code Device (vendor=0x00ff, product=0x0000)
16 button assignments.
0 axes assignments.

When I press a direction on the D-pad, I see one of the letters a to d printed to the console and when I press a face button, I see a number between 1 and 4. Press CTRL+C to exit the program.

If your loadmap program isn't working, then try a different version. I found version 0.3.1 worked best for my controller.

dunnieboy

i get the following

0 joysticks.
Found device Logitech K400 Plus(vendor=0x046d, product=0x404d)
Found device Wireless Controller Plus(vendor=0x054c, product=0x05c4)
Found device JOYMAP code Device (vendor-0x00ff, product=0x0000)
18 button assignments

here is my map file

axis vendor=0x054c product=0x05c4 src=0 target=mouse axis=0
axis vendor=0x054c product=0x05c4 src=1 target=mouse axis=1

When I try to use the controller i get no response.

I am using some driver for xbox360 controller installed from the retropie drivers configuration. Is is possible that is interfering ? ( I am using that for Mame etc)

ps : i just tried 0.3.1 - same result ...

I am wondering if i should try https://github.com/chrippa/ds4drv

i saw this post there

@dunnieboy I am using my PS3 controller wired so it may be worthwhile testing your controller via a USB cable.

dunnieboy

@dudleydes So ... this is almost working ... I got the mouse motion somewhat under control using the following ...

# General Mouse Mapping for DOSBox

 Map Mouse
axis vendor=0x054c product=0x09cc src=0 target=mouse axis=0 min=0 max=255 speed=100 deadzone=20
axis vendor=0x054c product=0x09cc src=1 target=mouse axis=1 min=0 max=255 speed=100 deadzone=20

#Mouse Buttons
button vendor=0x054c product=0x09cc src=1 target=mouse button=0
button vendor=0x054c product=0x09cc src=2 target=mouse button=1

The buttons don't work at all.

The mouse still drifts a bit to the right ... but its way better ... is the only mapper out there for Linux command line?

Check this out ... https://github.com/libretro/Lakka/wiki/DOSBox

Thanks

dudleydes

@dunnieboy The only other command line mapper program I am aware of is Joy2Key. I couldn't get this to work which is why I ended up using the Linux Joystick Mapper. This tool was created by the developer for his own use and made available to others to use as they wished. The fact that it works on the Pi with any success is due to good fortune rather than design.

I would suggest xboxdrv. You can find an example configuration for a PS4 controller connected via USB here.

The link you provide is for the libretro version of DOSBox which isn't available in RetroPie because of this issue.

i know is a older post, but here is my map for Worms Reinforcements (1996) for "Dragonrise inc, generic usb joystick", similar PS2 gamepad, using joymap-0.4.2 the dpad controls aim and movement, leftstick analog controls the mouse, L1 & Start buttons for Left - right mouse buttons, square is "enter", cross is "spacebar" and R2 for" control "& right trigger for "f9" ( a combination that quits emulator)
