      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.

      Currently running:
      Retropie 4.8.9 on a Pi Zero 2W (Overclock Settings: CPU 1400Mhz)
      ES-DE on a GMKtec K6 (Windows 11, 32GB RAM)

        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.

            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?

                  It should be ok with 0.220

                  My files are .j64 and I zipped all my roms.

                          Did you modify the two zip files in any way or just use them as is?

                          jaguar.zip (containing jagboot.rom and jagwave.rom)

                            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.cfg

                              add:

                              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

                                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:-

                                  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)

                                  Pi 5 4GB

                                    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.

                                      Just messing around with lr-vjag last night and it does appear that some games are running amazing! One question... I noticed that Tempest will throw odd glitches here and there...

                                      Here's a screen shot...

                                      Here is the frame just before the glitch:
                                      tempest glitch1.jpg

                                      And then here is the glitch:
                                      tempest glitch 2.jpg

                                      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.

                                        Huh... it looks like putting the emulator core in PAL gets rid of the flicker glitch? Does that sound right to you?

                                        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.
