      @mortalwombat lr-flycast is the only emulator on the Pi 4 that can support Naomi or Atomiswave games. Your best bet is to turn on frameskip in the core options to get them to run smoothly. The Naomi and Atomiswave are basically Dreamcasts that have been modified (and in the case of Naomi) upgraded for arcade hardware. The best emulator for Atomiswave/Naomi games is demul, but that's Windows-only.

        @g30ff really appreciate the reply! Yeah DL'd it (tho in binary mode, not from Source, not sure if it makes a difference w/ its performance?) and ran a few of the games mentioned above. Yeah, they all ran-- but shaky, with the audio slowed down too-- until I went in and adjusted the Frameskip like you said, and they all seemed to work a lot better (though w/ Giga Wing 2, there's already so much going on on the screen that it's nearly impossible to follow). Btwn. 1 and 6, I just set it to 1. Is there a different number you'd suggest??

        So I guess this means that I can run other Dreamcast titles? (though I'm guessing they may also have the Frameskip issue?).

        A few other questions though:

        1. I'd noticed for some of these games that-- at least on the site I usually DL my ROMS from-- some of them had rather large CHD files there too to DL. In fact, Capcom Vs SNK Mark of the Millennium (cvs2gd.zip for MAME) had one, but I didn't actually DL the CHD-- hell, I'm still not sure of what these are, and where to file them-- but it seemed to work OK. How essential are these files?

        2. For Sega Strike Fighter (sstrkfgt.zip for MAME), it loaded to the NAOMI logo, but gave me a warning like "Game Assignments are Incorrect. Set Correctly In System Assignments of Test Mode." I have another ROM for this labeled (Rev A)(Mame 0.150, should I try that one instead? Or how/where would I adjust those Assignments if it's not a matter of the ROM itself?

        3. Street Fighter Zero 3 Upper (the Japan version, sfz3ugd.zip, which was actually the only one included on this site besides the GBA version) also didn't load/again stopped at the NAOMI logo, with a warning "Error 01: This Game is Not Acceptable By Main Board." There was also a CHD file for this one that I didn't know what to do with. Could that be the reason why?

        Thanks!!

          Best practice is ... If it has a CHD file, then use it.

          If the game does not run, then most likely the reason is it needs the CHD.

          create a folder named sfz3ugd and then unzip the contents of sfz3ugd-chd.zip into it. (the file inside the folder should be called gdl-0002.chd)

          then transfer both into the naomi roms folder

          sfz3ugd.zip (which is game)

          sfz3ugd (which is the folder containing gdl-0002.chd)

          restart emulationstation and you're done.

          Note: games with CHD file take a little longer to start, so be patient.

          PS. I tested the game with lr-flycast ... works and runs great :)

            Yep, still the same "Error 01: This Game is Not Acceptable By Main Board" message (I'm assuming by "the naomi roms folder," you meant the Dreamcast folder?).

            Assuming I heard you right, I dropped a folder named " sfz3ugd" in there, containing the 109.2mb "gdl-0002.chd" file. And I'm aware that we may be getting our Street Fighter Zero 3 Upper ROMs from different sites-- neither of which we can discuss here-- but the 8.3mb "sfz3ugd.zip" file I have here, once opened (just to check if we're talking about the same ROM) produced a 36mb folder that contained:

            ....and that's still not covering the reason for the "Game Assignments are Incorrect. Set Correctly In System Assignments of Test Mode" error message I got for this sstrkfgt.zip MAME ROM I mentioned in #2 (which when I substituted for the other "[Rev A] [Mame 0.150]" one I mentioned didn't load at all, just returned to the Dreamcast menu).

            So, anyone got any ideas? :/

              In the same folder as the zip you need to create a folder called "sfz3ugd" and place the chd file there.
              Also ensure you're running the game from the zip and not the CHD

                  @crush Running Naomi/Atomiswave games is just like running an arcade game for MAME or FBNeo. Do not unzip the rom file itself. You should have a file called sfz3ugd.zip, and a .chd file called gdl-0002.chd. You would arrange it as follows, and then run the zip (As a warning, I do not have this particular rom to confirm, this is just as an example for a game that uses a CHD):

                  dreamcast
                  -sf3ugd.zip
                  -sf3ugd/gdl-0002.chd

                  Frameskip of 1 is usually enough for me as far as I can tell. You are usually better off with Redream for Dreamcast games over Flycast, where possible. Unfortunately the Naomi/Atomiswave games won't work in Redream, unless you use the Atomiswave to Dreamcast conversions.

                  Additionally, your Naomi/Atomiswave games need to be from a MAME rom set. Other dumps will not work.

                        Oops, sorry, yeah the Dreamcast folder is the default Retropie folder for Naomi and Atomiswave roms ... which i did not like.

                        So, i manually created Naomi and Atomiswave folders ages ago as i only wanted Dreamcast Console Games in the Dreamcast folder
                        ... and Naomi Arcade Games in the Naomi folder.

                          <system>

                          </system>
                        

                        Now onto file sizes ... sounds like we have a mis-match compared to my working game.

                        alt text

                        if i extract the sfz3ugd.zip then ... mine is not 36mb

                        Oh and the error... Error 01: This Game is Not Acceptable By Main Board

                        Could be caused by a bad BIOS ... i was getting that error on some games, re-downloaded a BIOS which was a different size and that fixed the issue.

                        The naomi_rem.zip was the original BIOS i was using ... and as you can see the BIOS i'm using now for Naomi (naomi.zip) is a larger file size

                          @crush I just left it at default, so I think 480? The problem is more like a glitch. If I play MK Gold or NFL Blitz, there is an odd jittery graphical problem. I really have to capture it to show what I mean.

                            @crush do you set any settings differently in Flycast in order to get the best performance? Redream just runs better for me IMO (Pi4 4GB).

                              @DreamcastKid appreciate your reply, my apologies for my own delay in noticing/responding as I haven't been too active on here lately (and have kinda been testing out other emulators/ROMs, but this-- and that unworking sfz3ugd.zip-- has been one issue that I've been meaning to get back to on here...).

                              So just so we're on the same page and there are no questions re: the Dreamcast/Flycast BIOS to get these NAOMI games to work (BIOS being yet another variable I've had to start wrapping my mind around here lately, since a lot of the console and arcade games I've come across thus far don't seem to use them), you're implying that the "naomi_rem.zip" one you mentioned IS an older one? (and thus probably no longer in use?). Because after you mentioned it there, I went Googling for it just now, but didn't seem to come across it.

                              I guess another thing I'm trying to understand is that a lot of these other emulators already seem to have their own designated folders where their BIOS files seem to go (and have recently started experimenting w/ the FDS/Famicon Disk System and ITS BIOS, which itself doesn't seem to have a designated folder for BIOS; so I wasn't quite sure if I was safe just dumping BIOS files-- like these Dreamcast ones, whatever the current/best one is-- in the general "BIOS" folder if there wasn't already a specified folder to file 'em in.

                              But yeah, this sfz3ugd.zip ROM I have is 95 MB unzipped (not sure if I missed how many MBs you said yours was?), with a 109.2mb chd file, annnnnd I just found/am currently DL'ing another chd file that seems to be 159mb... so again, part of the confusion is whether I have the right ROM/CHD combo.

                                @mortalwombat DreamcastKid is no longer a member of this forum.

                                @GreenHawk84 Any game in particular you got issues with? let me know and i'll record my settings and some gameplay so you can compare it for yourself.

                                  @crush geez yeah belated reply on my part, not sure if I noticed that when I checked my notifications. Well, guess I'm getting no answers from him, but I may use this thread if I have any more questions about NAOMI Roms.

                                  (side note, is the evidence/reason for the ban still posted for all to see? I'm always kinda morbidly curious about these things if only to know where the line is/was crossed, but I generally hope everybody's treating everyone with respect)

                                    @mortalwombat all i know is that he deleted every single comment he ever made, which broke allot of helpful threads, then an admin restored the posts and he was banned. I don't know what started it.

                                    All the bios files for Dreamcast and Naomi/Atomiswave go into "/home/pi/RetroPie/BIOS/dc"
                                    As per your rom size and content regarding sfz3ugd, yours was different as mine and Dreamcastkid, i posted the results of my extracted folder above, for instance yours does not contain "93c46.bin"

                                      @crush I appreciate your willing to provide some results. Blitz 2001 (I think, maybe just any Blitz) and MKGold were giving me really odd graphic issues on Flycast.

                                        Hey everyone. I just tried some NG.DEV.TEAM Dreamcast games with Flycast. Unfortunately, the core doesn't seem to work with the three that I tested (Gunlord, Fast Striker, and Gun Blade). I hear the volume, but no gameplay graphics appear (just a black screen). The same occurred with the Redream core (all on the Windows 10 x64 version of EmulationStation). Any ideas on what I can do to fix this issue? Thank you.

                                          @striderx99 Sorry, but Gun Blade should be Ghost Blade, and that particular game is from Hucast Games.

                                            @striderx99 cannot speak for flycast, but can confirm that all three named NG:DEV-Games run pretty well using lr-flycast.
