      @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>

                      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

                      alt text

                      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).

                            naomi_rem.zip

                            @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.

                              @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.
