      For some reason, the retropie setup script doesn't display an option to install daphne in either optional or experimental packages.

      experimental.png

      The installation guide I followed mentioned that this might happen, but didn't provide any information on how to get around it.

      This will install the main packages which are equivalent to what is provided with the RetroPie SD image. Note that this will be the 32-bit version of RetroPie. That means that some emulators such as Daphne (Dragon's Lair) will not work out of the box on this version. That is because Daphne and a few other emulators only have a 64-bit version released for use while this install is for the 32-bit CPU family.

      Have I installed the wrong thing altogether (32bit retropie instead of 64bit)? Or is there a simpler fix? Or is this a red herring? I'm guessing I also have other things missing that I'm not aware of, since I'm having trouble getting several games to work.

      I'm running on Lubuntu on an Atomic Pi.

        Daphne is enabled only for 64bit builds, if you installed an x86 only (32bit) distro, it will not be shown in the list.

          @mitu So does that mean there's no way to do this on an x86 processor? The Debian/Ubuntu docs don't say how to do a 64-bit build installation anywhere that I see. It seems like it should be possible, but I just don't see how to do it.

            They don't say, it's up to you to choose which version you want.

            It seems like it should be possible, but I just don't see how to do it.

            Just use a 64bit installation image for Debian/Ubuntu. Nowadays, recent versions of Ubuntu don't even provide 32bit install images for x86.

            EDIT: actually, I think Daphne is not enabled on any PC versions, just for the Pi, so don't reinstall your system yet.

              @mitu Sorry, just now realizing you were talking about Linux distro version. I'm using an 64-bit version of Ubuntu.

              But the RetroPie build itself seems to only be a 32-bit version. All of the instructions on that page seem to indicate that it will be a 32-bit installation when installing on an x86 system and that more work will need to be done for 64-bit emulators, but it doesn't say what needs to be done.

                I'm trying to follow the procedures listed in this post, but it's a bit hard to get the hang of.

                I did manage to get it to install daphne using this method, but I still don't see any games in emulation station.

                  Do you have a custom es_systems.cfg that you created ? What's the content of the daphne rom folder ?

                    @mitu The Daphne rom folder was indeed incorrect. I now have two copies of the rom file (roms/daphne/dlair.daphne and roms/daphne/roms/lair.zip) and the game shows up in emulation station (hopefully this is correct).

                    I'm still getting an error that vldp2 is not found when the emulator is starting up though. Still trying to figure this part out.

                      lair.daphne should be a folder, containing several files. Did you see the Daphne page in the docs ? It explains how the files should be structured.

                        @mitu Thanks for the pointer on the docs. I've gone through a lot of research and reorganizing since my last post, but it now appears to be working! There were two issues at play: bad rom directory structure and bad install of vldp2.

                        For reference to the curious, here's the problem I was having with vldp2. Every time the emulator started, it would give this daphne error saying ERROR: could not open the VLDP2 dynamic library (file not found maybe?):
                        daphne-error.png

                        For the sake of testing, I ran the following from the command line to see the console output:

                        /opt/retropie/emulators/daphne/daphne.sh $HOME/RetroPie/roms/daphne/lair.daphne

                        And at the end of the output, I saw this:

                        libvldp2.so: cannot open shared object file: No such file or directory
Could not load VLDP dynamic library!!!
Shutting down sound system...
Shutting down video display...

                        Well the install script for daphne is supposed to install vldp2 for you, but in my case, it wasn't doing that.

                        You can manually install the Linux x64 version of it by running the following in a temporary directory:

                        git clone https://github.com/DavidGriffith/daphne.git
cd daphne/src/vldp2

./configure --disable-accel-detect
make -f Makefile.linux_x64
sudo cp libvldp2.so /lib

                        My theory is that the script was compiling vldp2, but then failing to copy it to the /lib directory that it's supposed to get installed to (that last line in the command above).

                        I tried fiddling with the script a little to get it to work automatically, but gave up because it was hard to debug. If I can gather the motivation, I'll try to fix it properly and then send a PR to include the changes in RetroPie-Setup.
