https://github.com/retropie/retropie-setup/wiki/Dreamcast#for-mapping-non-standard-controller-via-folly

i ran the controller this is what i got -

[emulator]
mapping_name = MAYFLASH Arcade Fightstick F300
btn_escape = 296

[dreamcast]
btn_a = 290
btn_b = 289
btn_c =
btn_d =
btn_x = 291
btn_y = 288
btn_z =
btn_start = 297
btn_dpad1_left =
btn_dpad1_right =
btn_dpad1_up =
btn_dpad1_down =
btn_dpad2_left =
btn_dpad2_right =
btn_dpad2_up =
btn_dpad2_down =
axis_x =
axis_y =
axis_trigger_left =
axis_trigger_right =

[compat]
btn_trigger_left = 292
btn_trigger_right = 293
axis_dpad1_x =
axis_dpad1_y =
axis_dpad2_x =
axis_dpad2_y =
axis_x_inverted =
axis_y_inverted =
axis_trigger_left_inverted =
axis_trigger_right_inverted =

these are the numbers i got from a jtest -

up - 5: -32767
down - 5: 32767
left - 4: -32767
right - 4: 32767

x - 1:
o - 2:
square - 0:
triangle - 3:

etc .....

where i place these number & which

@Slugz

It's been a while since I've done it myself, but from memory, you would add the number codes you got from running /opt/retropie/emulators/reicast/bin/reicast-joyconfig and input them into the Reicast mapping file. According to the wiki entry, you'll need to create it yourself. I'll have to defer any more specific questions to someone else, as I have had Reicast uninstalled for some time due to poor performance on the Pi3.

don't know how.

@Slugz
I believe you put those controller mapping info into a files named something like this /opt/retropie/configs/dreamcast/mappings/MAYFLASHArcadeFightstickF300.cfg

Than edit /opt/retropie/configs/dreamcast/emu.cfg to tell the emulator to use your custom controller mapping:

evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/MAYFLASHArcadeFightstickF300.cfg
evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/MAYFLASHArcadeFightstickF300.cfg

The Input section should be between the [dispmanx] and [omx] sections. Hre is that part of my emu.config:

[dispmanx]

maintain_aspect = yes
width = 640

[input]
evdev_device_id_1 = 0
evdev_device_id_2 = 1
evdev_device_id_3 = -1
evdev_device_id_4 = -1
evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/controller_TwinUSBJoystick.cfg
evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/controller_TwinUSBJoystick.cfg
joystick_device_id = -1

[omx]
audio_hdmi = yes
audio_latency = 100

I have never done a manual edit of this config file, so I'm not sure what you need in the evdev_mapping_X lines or the joystick_device_id_X line. You can try pasting in what I have and changing TwinUSBJoystick.cfg lines to

evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/MAYFLASHArcadeFightstickF300.cfg
evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/MAYFLASHArcadeFightstickF300.cfg

Note, check /opt/retropie/configs/dreamcast/mappings for the exact filename. It might be something like controller_MAYFLASHArcadeFightstickF300.cfg. All of y listed configs start with "controller_" except keyboard.cfg (I am running Retropie 4.1)

@Slugz

Oh yeah, in the /opt/retropie/configs/dreamcast/emu.cfg file you need to change evdev_device_id_1 & 2 to equal the number of the joystick you want to use.

So if you want your MAYFLASH Arcade Fightstick F300 to be player 1 and your 8Bitdo SNES30 GamePad to be player 2. From what you posted above the Mini Keyboard is using 0 and 1 and the MAYFLASH is 2 and the 8Bitdo is 3.

You'd do something like this:

[input]
evdev_device_id_1 = 2
evdev_device_id_2 = 3
evdev_device_id_3 = -1
evdev_device_id_4 = -1
evdev_mapping_1 = /opt/retropie/configs/dreamcast/mappings/controller_MAYFLASHArcadeFightstickF300.cfg
evdev_mapping_2 = /opt/retropie/configs/dreamcast/mappings/controller_8BitdoSNES30GamePad.cfg
joystick_device_id = -1

The -1 means no joystick which we used for player 3 and 4 and also have evdev_mapping_1 & 2 to point to the matching joystick mapping config files.

And if you want 2 players at the same time, then you need to add this to the bottom of that same emu.cfg file:

[players]
nb = 2

I'm stumped.

Please post the contents of your /opt/retropie/configs/dreamcast/mappings/controller_MAYFLASHArcadeFightstickF300.cfg and /opt/retropie/configs/dreamcast/mappings/controller_8BitdoSNES30GamePad.cfg files (or whatever controller mapping files that are referenced by your /opt/retropie/configs/dreamcast/emu.cfg).

Also post your current contents of your /opt/retropie/configs/dreamcast/emu.cfg file as well.

Sometimes something as little as a typo can cause the whole emulator not to work.

evtest then just hit Ctrl+C to exit after you get your event number.

I did notice something in your emu.cfg. There's spaces in your controller mapping cfg file name. Try putting quotes around them like this:

evdev_mapping_1 = "/opt/retropie/configs/dreamcast/mappings/controller_8Bitdo SNES30 GamePad.cfg"
evdev_mapping_2 = "/opt/retropie/configs/dreamcast/mappings/controller_8Bitdo SNES30 GamePad.cfg"

Or you can just rename them to controller_8BitdoSNES30GamePad.cfg to remove the spaces.

Also you'll want to add this somewhere to your emu.cfg file if you want 2 players:

[players]
nb = 2
