Create lr-mame2003 button mapping with jstest values

[noBios]

The jstest values correspond in a sensible way to what is printed on the PCB of the device

jstest --normal /dev/input/js0
Driver version is 2.1.0.
Joystick (DragonRise Inc.   Generic   USB  Joystick  ) has 7 axes (X, Y, Z, Rx, Rz, Hat0X, Hat0Y)
and 12 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4, BaseBtn5, BaseBtn6).
Testing ... (interrupt to exit)
Axes:  0:-32767  1:     0  2:     0  3:-32767  4:-32767  5:     0  6:     0 Buttons:  0:off  1:off  2:off  3:off  4:off  5:off  6:off  7:off  8:off  9:off 10:off 11:off 

iE I press what is supposed to be Button 0 and = shows as on while I hold it etc.

I could so far not make any sense of evtests output as that shows for starters way more events then my dragonrise board has inputs and no clear indication which would be "analog" labeled.

So I would prefer to set up a config file matching the jstest values. But the examples and docs only show the 8bitdo(?) layout. How does that work? Is there a tool that gives me those values from jstest outputs? A translation table?

example:
/opt/retropie/configs/psx/retroarch.cfg

input_player1_a = "x"
input_player1_a_axis = "nul"
input_player1_a_btn = "nul"
input_player1_a_mbtn = "nul"
input_player1_analog_dpad_mode = "0"
input_player1_b = "z"
input_player1_b_axis = "nul"
input_player1_b_btn = "nul"
input_player1_b_mbtn = "nul"
input_player1_down = "down"
input_player1_down_axis = "nul"
input_player1_down_btn = "nul"
input_player1_down_mbtn = "nul"
input_player1_gun_aux_a = "nul"

I only have Button/Axes numbers, so no "down", "x", "b" or "z"

While researching I stumbled over these lines in the Skeleton config:

# Input device buttons.
# Figure these out by using RetroArch-Phoenix or retroarch-joyconfig.
# You can use joypad hats with hnxx, where n is the hat, and xx is a string representing direction.
# E.g. "h0up"

But where do I find these 2?
Both just returned me a command not found error.

RetroArch-Phoenix and retroarch-joyconfig

Also I don't have enough buttons to go through the auto config tool, so that simply is not an option. At least it seems so since I could not find a way to skip buttons or end it before going through all of it.

Tried the obvious things like using a keyboard:
press esc
press tab (to select the exit button)
press arrow keys (to select exit button)
press enter, well just for good measure at this point

Logging into ssh to check if it maybe already saves progress mid way through:

ls /opt/retropie/configs/all/retroarch-joypads
Microsoft X-Box 360 pad.cfg  Microsoft X-Box 360 pad.cfg.bak

Well, that seems like a no, so I can't just shutdown now and just fix up the file manually later with the intel obtained from the partially configured one.
