My jamma joysticks change device numbers on every reboot.
For example: turbo pacman uses joy 3, on next reboot joy 3 changes to joy4 and i have to resetup the controls.
Since I stream and entertain this is beyond annoying and really hurts my ability to play games.
3 of my sticks are usb and i can use udev in linux to map them to the same joy number every boot.
but i cant control the jamma sticks the same way.
is there any way to do this?
thanks

i just finished some research on this.
i booted and my main joy came up as joy4 when selecting it using mame
i kept rebooting until it said it was joy2.
i tested js0 in linux and its the same joystick
its not a linux issue
its a mame issue

linux always sees that joy as js0

not sure what controls how mame numbers joysticks but i have to find it.
before i go nutz

i think this answers the issue:
https://docs.mamedev.org/advanced/devicemap.html

Can you assign your USB controls to /dev/input/js3 (and above)? If you can't re-assign the JAMMA inputs that may be a way around them and the hotkeys using js0 (p1), js1 (p2) and js2 (part of the hotkey system).

EDIT: just saw your updates... weird that MAME is remapping if they appear right to the kernel... is that over all MAMEs or a particular version?

i have my 3 usb sticks mapped to joy 4,5,6 using linux on boot
linux maps the jamma joys to js0 -> js3

according to the article i found mame is the goofball in the room.

I was able to use mame230 to get the device id's for my jamma sticks
mame172 doesnt output that info

to get the info change to the mame folder:
>cd /home/pi/mame230

then run the mame binary and use the verbose switch as such
>./mamearcade -v

to preserve a copy redirect the output to a text file as such
>./mamearcade -v >joy.txt

i am making a mapdevice xml file to permanently assign all jamma devices to specific names like joy1->joy3

i will share it when i get it tested

apparently i can do this also for the usb joysticks rather than having linux do it using udev rules.

Using the mame230 verbose output which shows the device id's for my jamma joysticks I was able to make this file called jamma.cfg:

<mameconfig version="10">
<system name="default">

<!-- Jamma Version 1.0 input configuration file -->
<input>
<mapdevice device="0300000009d200001105000011010000" controller="JOYCODE_1" />
<mapdevice device="15000000010000000100000000010000" controller="JOYCODE_2" />
<mapdevice device="0000000058626f782047616d65706100" controller="JOYCODE_3" />
<mapdevice device="15000000010000000200000000010000" controller="JOYCODE_4" />
<mapdevice device="15000000010000000300000000010000" controller="JOYCODE_5" />
<mapdevice device="15000000010000000300000000010000" controller="JOYCODE_6" />
</input>
</system>

</mameconfig>



will it work, have no idea.
it seems only mame172 and higher support this and have a ctrlr folder for controller configs.

gonna give it a try

Did you have any luck with it?

been in hospital many days.
will get to it.

I hope you are OK. Get well soon.

I got this last night. Its a blast.
