To install (manually) a system like Jaguar with Lr-mess, fallow this thread:
https://retropie.org.uk/forum/topic/22600/how-to-emulate-bally-astrocade-vtech-creativision-and-emerson-arcadia-2001-in-lr-mess

Download mame0225s.exe on https://www.mamedev.org/release.html , installe It and go in "hash" folder to get jaguar.xml file.
To run Lr-Mess, you need to match the names of your roms with the list in the hash folder (jaguar.xml). Copy that file (jaguar.xml) and paste It in

/home/pi/RetroPie/BIOS/mame/hash/

BIOSes are

jaguarboot.zip
jaguar.zip
jaguarcd.zip

Copy those Bios in the main rom folder, not bios folder.
/home/pi/RetroPie/roms

Now Create your system:

In /opt/retropie/configs/jaguar

emulators.cfg

lr-virtualjaguar = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-virtualjaguar/virtualjaguar_libretro.so --config /opt/retropie/configs/jaguar/retroarch.cfg %ROM%"
lr-mess = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mess/mess_libretro.so --config /opt/retropie/configs/jaguar/retroarch.cfg %ROM%"
default = "lr-mess"

retroarch.cfg

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/jaguar/"

#include "/opt/retropie/configs/all/retroarch.cfg"

in /opt/retropie/configs/all

platforms.cfg

jaguar_exts=".j64 .jag .zip"
jaguar_fullname="Atari Jaguar"

in /opt/retropie/configs/all/emulationstation

es_systems.cfg

   <system>
    <name>jaguar</name>
    <fullname>Atari Jaguar</fullname>
    <path>/home/pi/RetroPie/roms/jaguar</path>
    <extension>.j64 .jag .zip .J64 .JAG .ZIP</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ jaguar %ROM%</command>
    <platform>jaguar</platform>
    <theme>atarijaguar</theme>
  </system>

@DTEAM this is amazing thank you so much.

For Jaguar with Lr-Mess , you must set the Lr-mess deadzone for D-Pad(ex: for AVP)
and to adjust the sound.
It seems to create some sound problems and control problems for some games

Jaguar doesn't have analog input so I don't see why you would need to set a deadzone? I haven't and everything seems fine?

DTEAM

@zerojay

It's maybe similar to the mouse problem with CD-I

For some games. Everything go to right and down without touching controller

In PVA (predator vs alien), the character move alone and when I play with deadzone , It stop.

In Double Dragon V. We don't have the main combat game soundtrack. When I push start (pause) and after (not in same time) push B or A to access volume control in the game, the volume go down alone.

For CD-I,I enabled the mouse to fixed the movement problem, I'll see If It create the problem for Jaguar

DTEAM

In /opt/retropie/configs/all

retroarch-core-options.cfg
My setup

mame_current_frame_skip = "1"

In the retroach menu Main menu/settings/Input/
The Analog Sensitivity must be fix at 0.3
With that, the controllers issues are fixed. Forget about what I said for deadzone.

For now, No solution for sound in some games

I am getting this output on RunCommand now: https://pastebin.com/SrmvBbK0

202.[libretro INFO] ARGUV[0]=atarijaguar
203.[libretro WARN] Driver atarijaguar not found -1
204.[libretro WARN] Game not found: alien vs predator (world)
205.[libretro INFO] RES:-2

Does this suggest my BIOS is at fault? I am unsure about the game name issue, as I think I have that right as per the Hash file in the Mame directory.

If anyone can quickly diagnose this, thank you. Otherwise, don't worry - I can stick with virtualjaguar.

DTEAM

your system must be named jaguar and not atarijaguar. Lr-mess is really picky with machines names.

See my post above for es_systems.cfg and others

see : http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=jaguar&arcade_only=0&autosearch=1&lang=en

for quick machine info with MAME/ Mess

Ahhh okay, I thought I could include this within my existing atarijaguar folder, I didn't realise it was so specific. Thank you!

@AdamBeGood

you have to change everything for jaguar (roms folder, config file, emulators.cfg (also for virtualjaguar), ect. ) , excepted your theme.

There's no need to do that with the lr-mess-jaguar.sh I provided above. I have both lr-virtualjaguar and lr-mess-jaguar using the atarijaguar roms folder just fine.

@zerojay
With your method, I agree. It's maybe precompiled with some tweaks. Probably "enable softlist = off and maybe boot from CLI = off.
Did you have sound issues with some games like Double Dragon V or Rayman with this setup. Is It fixed?

DTEAM

@zerojay
I read the script that you proposed and It's very nice!
https://raw.githubusercontent.com/zerojay/RetroPie-Extra/master/scriptmodules/libretrocores/lr-mess-jaguar.sh
People should use It. It's easier.
The two methods work.

I haven't tried it yet, I'm working right now so I'll look at it a bit later.

@zerojay I tried to install your scriptmodule, but it seems "run_mess.sh" script can't be found. It's supposed to be in ~/Retropie-Setup/scriptmodules/ but it's not...

DTEAM

@zerojay
In the jaguar.xml file , they identify sounds issues, black screens, gfx issue and more per video games for Lr-Mess.
Both of those emulators are less than perfect. A lot of issues with those two.
We have to test games and get the best emulator for each one of those.

See above.

George Spiggott

@DTEAM Are either of them currently supported?

DTEAM

@George-Spiggott
I don't know for lr-virtualjaguar

In whatsnew_0225.txt (2020-09-30) (MAME) Fresh from today
https://www.mamedev.org/releases/whatsnew_0225.txt

We can read:
-jaguar.cpp: Document alternate ROM labels for Maximum Force v1.02 [Brian Troha]

Arcade game supported by jaguar.cpp, nothing big

Maybe somebody work on that

zerojay

The VirtualJaguar developer basically quit right after someone from libretro was basically harassing him to try to get a core made and he wasn't interested in doing anything but working on his emulator. They basically made the core themselves in spite of him and the emulator didn't really get updated again after that.

I don't think anyone in particular is working on Jaguar support in MAME at the moment (beyond documentation).
