Easy Tutorial for Lr-Mess scripts
1- Do a SD card backup and install precompiled lr-Mess.
2 - Download RetroPie-Setup-master from here Click Code and select Download zip
3- Unzip this file on your desktop
4- Open FileZilla, connect your Pi and go to /home/pi/RetroPie-Setup/scriptmodules/
5- Now go in your downloaded file and go to C:\Users\??????????\Desktop\RetroPie-Setup-master\scriptmodules and copy those files to your Pi (/home/pi/RetroPie-Setup/scriptmodules/)
To:
NOTE: files with « original » mention are just my backup files. Not important.
6- Now, go in C:\Users\???????????\Desktop\RetroPie-Setup-master\scriptmodules\libretrocores and get lr-mess scripts you want. Do some cherry picking.
7- Copy those to /home/pi/RetroPie-Setup/scriptmodules/libretrocores
8 - For Jaguar, copy zerojay script in a copy of an existing lr-mess-???.sh file and rename It lr-mess-jaguar.sh . Don't use a new file. Delete the content of a copy and add the script and rename that file. I had issues with "cut and paste" in a new file :
to
9- Copy lr-mess-jaguar.sh in /home/pi/RetroPie-Setup/scriptmodules/libretrocores
10 - Now reboot your Pi, Go in Retropie Setup, Go in experimental section and install what you want.
11- Put your BIOSes files in the regular BIOS folder (FOR JAGUAR: jaguarboot.zip, jaguar.zip, jaguarcd.zip)
12- Select Lr-Mess-jaguar (or others if It’s not jaguar system ) when you load a game
13 - If you dont like the control setup. Connect a Keyboard, press TAB, go in Input (This Machine) and set your controller(s).Give me some feedback If It's work or if you encountered problemes.
For cool stuff see also my Tutorial : Handheld and Plug & Play systems with MAME
You also will found a link to gamelist.xml and downloaded images for lr-mess system not supported by site like ScreenScraper.

@dteam Thanks very much for the info, I'm mad busy at work at the moment so may take a bit before I give it a go but wanted to say thank you as a placeholder until then!
-
@adambegood This is really great, thanks. I've installed Jaguar-mess almost perfectly, I think.
I think I'm still having BIOS issues though. What should be the contents of the various bios .zip files? Currently I have the following:
jaguar. zip ( jagboot.rom [49kb] and jagwave.rom [3kb])
jagboot.zip (jagboot.rom [49kb])
jagcd.zip (jagcd.rom [85kb])Here's my verbose log: (Pastebin seems to be down for me, I'll edit the post when it comes back up)

-
I've changed my jaguar.zip to replicate yours and games still don't load. I also fixed jagcd.zip to be jaguarcd.zip.
Will run through the whole process again to see if I missed anything.

@george-spiggott
Try to Get your BIOSes files from MAME Romset 0.224 or later. Have you installed lr-Mess? Try to install another system in the list with the good BIOS. If It works, good chance you have a Bios problem with Jaguar. -
@dteam When I copy over the files in step 5, my RetroPie Setup won't open up. There are various errors that I can send you.. I don't know what I have done wrong here. When I put the old files back, everything is fine.
-
@adambegood
Do you have a Pi4. -
-
@dteam By pure chance I have just got a full 2020 0.220 romset for another purpose. There are only two .zips, they are:
jaguar.zip (contains jagboot.rom and jagwave.rom)
jaguarcd.zip (contains jag_cd.bin and jagdevcd.bin)I've just got a 0/224 set of jaguar BIOS. They looks the same but I will try the newer ones later tonight.
I can still use my . j64 and .jag roms that I use with Virtual Jaguar with MESS right? I better clear that up before I continue?
-
@george-spiggott
It should be ok with 0.220My files are .j64 and I zipped all my roms.
-
@george-spiggott
@adambegood
Other option
Try the new Folly methodSee at the end of that post
new scriptmodules (lr-vice-xvic, gsplus, proper lr-mess integration!) -

@adambegood
Good to hear ! -

Did you modify the two zip files in any way or just use them as is?
jaguar.zip (containing jagboot.rom and jagwave.rom)
jaguarcd.zip (containing jag_cd.bin and jagdevcd.bin) -

jaguarcd.zip (containing jag_cd.bin and jagdevcd.bin)I just had the one jaguar.zip with everything in it. Let me double check tomorrow as to what the contents were but I think it contained jagboot.rom and jagwave.rom and then jaguarcd.zip was also within in, including the two .bin files.
I just left it as is from the .224 romset.

Another way to run jaguar with MAME standalone (like MESS without Lr)go in /opt/retropie/configs/jaguar
open your emulators.cfgadd:
mame-jaguar= "/opt/retropie/emulators/mame/mame -c jaguar -cart %ROM%" mame-jaguar-autoframeskip= "/opt/retropie/emulators/mame/mame -c -autoframeskip jaguar -cart %ROM%"Note: sometime better performance without autoframeskip and sometime with It.
To set your "Input (general)" and "Input(this Machine), follow step 10 and 11 of this Tutorial -----> Tutorial: Handheld and Plug & Play systems with MAME
For cheat codes: (SOLVED) MAME "standalone" Cheats for systems like Coleco, Arcade and more

It seemed quite appropriate to resurrect this thread rather than start a new one. I noticed recently that VirtualJaguar has been updated on X86 systems and has probably been updated on the Pi as well. The update fixes several issues, most notably the weird screen shape on Atari Karts. Has anyone noticed any other improvements?
-
@George-Spiggott I haven't had a proper look but it appears to be this change here:-
https://github.com/libretro/virtualjaguar-libretro/pull/77#issue-1453824369
Any game that changes resolution midgame should have an improvement (I'm sure most 32bit era consoles did this no in certain games? Resident evil is the classic example)

With Pi 5, Lr- virtualjaguar works very well for some games . Major performance gain !
Same comment for MAME 0.266, but with MAME, some games have issues.
