      @majorocd There are multiple revisions of the Sega CD BIOS for the U.S.. (e.g. G1-the drawer type underneath the Genesis, G2-the top loader on the side on the Genesis, the CDX) Each had a different U.S. BIOS file. (just a reminder, that tripped me up)

          I did not disable the Runcommand launch menu.
          I went into the config and verified that it is enabled.
          When I hit a button right after launch, it did not go into the launch menu.

          Retropie by default has both lr-genesis-plus-gx and lr-picodrive installed.
          I uninstalled lr-genesis-plus-gx and tried it again. It brought up a launch menu, but the only option was to choose which emulator (only choice, of course being lr-picodrive).
          It still wouldn't launch the game.

          I then uninstalled lr-picodrive and reinstalled lr-genesis-plus-gx from binary.
          Now, when I hit a button, it brings up the full launch menu.
          It still wouldn't launch the game.

          This is the runcommand.log

            The BIOS file is not found by the emulator:

             [libretro ERROR] Unable to open CD BIOS: /home/pi/RetroPie/roms/segacd//bios_CD_U.bin.

            because:

            [WARN] SYSTEM DIR is empty, assume CONTENT DIR /home/pi/RetroPie/roms/segacd/Adventures of Batman and Robin, The (USA).cue

            RetroArch looks up the BIOS files in the System Dir, which RetroPie sets - by default - to the bios folder where you copied your BIOS files. Did you use the 'Reset Configuration' option in RetroArch's menu ? This would explain why the BIOS folder was reset.

              I don't recall if I used the 'Reset Configuration' option in RetroArch's menu.
              How do I check to see if it is pointed to the correct folder?

                        Not sure if that would help, since you haven't said what you changed that reset the defaults. What you could try is to rename the configuration file for segacd (\\retropie\configs\segacd\retroarch.cfg) and then reinstall the lr-genesis-plus-gx emulator. The re-install would re-create the correct configuration file and you can then try again to see if the game works.

                              After trying everything I could think of (including what you suggested), it was still not working.

                              I think I may have reset something while trying to configure the controls for PSX for a couple of games.

                              I have another microsd card, so I installed the Retropie image on that, and now SegaCD is working.

                              Thank you again for your help and prompt replies!

                                  Just wanted to add that I have the same issue as OP. I have verified my games and bios, and just get a black screen. Have reinstalled retropie on my pi4 8gb as well, with no discernable difference.

                                  Currently, I'm using the same (renamed) bios and games in Picodrive. But it would be nice to use Gen Plus as well (especially for .chd's)

                                  This was my crash report from the other day: pastebin

                                      @ilchymis From your log, look like the BIOS files found, but the crash suggests they might not be correct - see if the checksums for the files are identical to the ones in the Docs.

                                        I would just like to add that the BIOS file for lr-genesis-plus-gx is different from the one for lr-picodrive.

                                        It sounds like your lr-picodrive BIOS file is correct, while the one for lr-genesis-plus-gx is not (as mitu has suggested).

                                        I'm pretty sure your issue is not the same as mine, since my BIOS files were correct. It simply couldn't find them due to mis-configuration.
