@AdamBeGood I was referring to in general yes, thanks, and @DTEAM that's great. I'll need to 'mess' around with lr-mess when i get a chance.

DTEAM

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.

DTEAM

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.

DTEAM

@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
