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.

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.

Other option
Try the new Folly methodSee at the end of that post
new scriptmodules (lr-vice-xvic, gsplus, proper lr-mess integration!) -

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. -

Here's a screen shot...
Here is the frame just before the glitch:
And then here is the glitch:
And then the next frame it goes back to normal. Any ideas? I have in the options Fast Blitter turned on, but that is my only option selected.

The ROM I have is marked "world" so not sure if there were specific NTSC or PAL roms.

ROM with (World) tag means that game version got released across all regions with exact same data, so it runs in NTSC and PAL modes without Region Lock, although I have never seen a ROM with "(World)" Tag that is PAL optimized in the consoles before Sega Dreamcast.

No glitch on my side with lr-vjag. I'm running tempst2k.zip (from MAME Romset) with the default settings and Vulkan
