      Hello! So, I recently upgraded from my Pi 4 to a Pi 5, as I had heard that the increased processing power made it easier to run higher-end games. Some games I was particularly excited to get running are Killer Instinct 1 & 2 for arcade and the arcade version of Neo Geo Battle Coliseum. Before I formatted my SD card to reinstall Retropie on an OS supported by the Pi 5, I backed up all my roms and BIOS files to an external drive. I also want to mention that, while not exactly playable, these games still ran on my Pi 4. Now, however, even with the original roms and BIOS files that worked fine on my Pi 4, these games don't open at all on my Pi 5. In fact, in addition to Neo Geo Battle Coliseum, none of my Naomi or Atomiswave games are running. Can anyone help me figure out what's going on here? Thanks! System and error info below.

      Pi Model or other hardware: Raspberry Pi 5 4 GB
      Power Supply used: Raspberry Pi 27W Power Supply
      RetroPie Version Used: 4.8.9
      Built From: Manual install on top of Raspberry Pi OS Lite

        @Val_Ainsley Okay, I have an update, gang. I did get Killer Instinct working. I realized that lr-mame2003 is only at version 0.78, so I just needed to find that romset (which proved to be more of a chore than I'd hoped, but I found it eventually) and download it from there. However, I still have not found a solution for getting my Naomi/Atomiswave games running on lr-flycast.

          Check if you have the required bios (awbios.zip) and the ngbc.zip contains the correct files.

            @mitu Yes, I've cross-referenced my roms with the list you have provided, and they all contain their correct files. I also have the proper BIOS files - awbios, naomi, and naomi2 - stored in the /pi/RetroPie/BIOS/dc folder. I'll also clarify that this is not just an issue with Neo Geo Battle Coliseum. It's just the game I chose to use as an example for the purposes of this post.

              Are N64 games working for you ? By default the Pi5 linux kernel uses the 16k memory pages, which is incompatible with most emulators that use a dynarec (dynamic code recompiler). This includes the N64 emulators and Flycast also.

              I can't reproduce your error with a valid set of BIOS files and the ngpc.zip rom, using a Pi4 though, which doesn't have the 16k kernel loaded

                @mitu Yeah, N64 works just fine. Also, I installed lr-flycast-dev to see if the roms would work, and they did. However, there are some glitches. A couple Guilty Gear titles (Guilty Gear X and Guilty Gear XX) have missing sounds when pressing start, Neo Geo Battle Coliseum has quite a few glitchy character sprites, and Spawn: In the Demon's Hand has a few small graphical glitches. In addition, the test menu button doesn't work in lr-flycast-dev. I'm glad I have some way to get these roms running, but these glitches didn't exist in lr-flycast on my Pi 4, so I'd still like to get them working there.

                  Could it be that it's just a compatibility issue between lr-flycast and the Pi 5 that's preventing my games from running in the original core?

                  I doubt that.

                    @mitu Weird. Well, I know for sure that the BIOS files are valid, since the roms run in lr-flycast-dev. I'm at a total loss as to why lr-flycast just isn't able to read them. Should I generate a verbose log in lr-flycast-dev to look for any discrepancies?

                      No. Did you modify config.txt to boot with the 4k memory pages kernel?

                        @mitu No. Is it the one in /boot/firmware? How do I change that setting? Sorry, I'm not well-versed in the technical side of all this.

                          @Val_Ainsley Add a line with kernel=kernel8.img to config.txt and reboot.

                            @mitu Okay, this fixed the problem with lr-flycast, but now, my audio doesn't work running things on kernel 8. No audio from emulationstation, retroarch, or even from running speaker-test in the terminal. Audio only comes back when I comment or remove the kernel line from config.txt. I have my amp and speakers connected by a 3.5mm jack into a USB audio adapter.

                              Haven't heard this one yet - but I don't see how that affects the audio output since it's just the same kernel but tuned with a different parameter.

                                @mitu Yeah, I figured it shouldn't have any effect on audio output. The only audio settings I've changed are in /usr/share/alsa/alsa.conf, where 2 is the number of my audio device:

                                defaults.ctl.card = 2
defaults.pcm.card = 2
