      @Winklepicker Just to be clear, you're using https://github.com/fabrice-martinez/neocd_libretro and not lr-fbalpha ?

        The one I am using was the link that MajorDangerNine added onto the first couple of posts on the thread, is that the correct I should be using?

        Readme says :
        put "lr-neocd" in "/opt/retropie/libretrocores".

        Put "neogeocd" in "/opt/retropie/configs".

        Put BIOS "/home/pi/RetroPie/BIOS/neocd".

          @Winklepicker You'll have to build it from source manually since there's no script for it in retropie-setup. No, it does not fix the images. That's why I said to open the issue at the dev's github if you wish.

            The emulator runs full speed on a stock RPi3B, and I even had the zfast CRT standard shader running with it. The emulation hacks are wonderful as well. Not enough processing power overhead to run RetroArch's RunAhead latency hack though.

            No idea if anyone wants this, but I threw together this manual install for NeoCD. It was compiled on my RPi3B, but I guess it'll work on other Pi versions. if there are any problems, don't hesitate to tell me.

            @MajorDangerNine

            Please could you compile the latest version for RPI 3 B+ from Fabrice Martinez Github as you did previously and share it?
            Also please provide steps on how to install it in Retropie.

            Thank you a lot for this! (Many Noobs will appreciate!) :-)

              @thorias See if this works. Can't test it at the moment, but it looks like it compiled correctly.

              Recompiled the latest build using set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -march=armv8-a+crc -mtune=cortex-a53 ${BASE_CXX_OPTIONS}"), and included an updated README for how to install/use it.

                That's brilliant! Thanks a lot again for this!! 8-)
                I'll test it and report back.

                  Thank you MajorDangerNine for compiling new build

                  You listed the instructions very clearly and precise in the zip file for installing manually, I tested the new build and all is working nice as "Samurai Showdown 3" also works perfect.

                  Many thanks

                    I see a lot of ppl wanting to use neocd_libretro in this topic, is there any issue with lr-fbalpha for running ngcd games ? Afaik, ngcd emulation in lr-fbalpha should be perfect after the january/february updates.

                      @barbudreadmon I guess people either want the emulation hacks it offers, or they aren't aware that lr-fbalpha can emulate Neo Geo CD.

                      Seems like a Neo Geo CD page in the RetroPie Docs would help. I'd make one, but pretty sure I would break the documentation if I tried to add a page to it.

                        I'm not too familiar with the usefulness of the various bios options, afaik any game, protected or not, works in lr-fbalpha as long as you have neogeo.zip and neocdz.zip in your fba bios folder. And for the cd speedhack/skipping options, trying to reduce even more the "less-than-2-seconds-loading" in lr-fbalpha seems overkill. The only issue might be that it's kinda restrictive on the iso formats (only supports ccd and single file cue/bin)

                          @barbudreadmon I use this over lr-fbalpha because of the speedhacks, yes. The dev also has a slight interest in adding .chd in the future. I faintly remember you saying you had little interest in neocd so I'm not expecting speedhacks in fbalpha anytime soon if ever.

                            That's true, but since there was some motivation to rewrite the ngcd driver upstream, i made sure to report all bugs and feature requests. As i said, the loading speedhacks are already in fbalpha, loading speed might be x15 or something.
                            Upstream have no plans to add chd support so a libretro bounty was opened about it.

                              I just tested it now and is 100%!! Great clear instructions!

                                Just to update that CHD has been recently added to the emulator. Given the benefits over FBNeo and that it has been added to Libretro, would it be possible to add this emulator to Retropie?

                                  @janderclander14 I compiled the new version with chd support: https://drive.google.com/open?id=12VrMatgrAKIpXqlUPeSmvDcIFKEYKIzV

                                  Install MajorDangerNine's first and then replace it with my binary.

                                    @Darksavior I updated my archive/guide with the binary you made. Updated some other parts of it as well related to the Final Burn Neo change and newly recognized BIOSes.

                                      @Darksavior Thanks a lot! This saved me like 17gb! By the way, here you can find a very comprehensive list of neoCD games with arranged music:

                                      http://www.neo-geo.com/forums/showthread.php?58668-Which-Neo-Geo-CD-Games-Have-Arranged-Music-New-Thread&p=3746963&viewfull=1#post3746963

                                      And here a description of the games that have some changes (for the better or the worse) w.r.t. AES. It's in French, so you may need Google translator
