      Hi everybody

      I built my own retropie 3 machine and everything works fine for me apart the Megadrive...
      It starts loading the rom then the screen becomes black and the list of roms appears again.
      I tried to search for common problems but everything I tried failed.
      I checked also the name of the roms but are correct.
      I ran the emulator with the verbosity, if you can help would be great, I am becoming mad :|

      Parameters:
      Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/megadrive/retroarch.cfg "bash" --verbose --appendconfig /dev/shm/retroarch.cfg

          A small update: thinking about the rom extension I tried also several formats: .smd, .bin, .gen and .zip
          none of them is working

            @cristianpixio when you say you 'tried several formats' what do you mean? you downloaded them from different places in different formats?

                @cristianpixio I know this isn't really an answer or what you want to hear but Megadrive is very straightforward to get running. So this suggests to me 2 things, you've been unlucky and gotten a bad set of ROMs or you are doing something which you haven't mentioned which is preventing the ROMs from running. You aren't just changing the file extensions randomly hoping for them to work, are you?

                  Alex thank you for your reply, I am not changing the extension, I am just downloading the same rom from different places in different file formats. All other systems are perfectly working.
                  I can add that my rom set (for all system anyway) are placed on an external Hard Drive and not on the SD card.
                  I changed the conf file with the right path (in my case is MEDIA/USB0/etc.... ).
                  I tried also to delete everything and placed just one/two roms thinking about maybe a corrupt rom in the romset.
                  The romset that I am using works perfectly for other systems (ex. XBOX first model, WII or PSP).
                  I can try to rebuilt everything from scratch and testing the MEGADRIVE romset immediately without changing the conf file

                    @cristianpixio megadrive/genesis rom folder is a symbolic link. i'm guessing whatever way you set up your external drive doesn't support them. the ways we suggest are: https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive

                      solved it! I just rebuilt the filesystem in another SD card and now everything is working.
                      Probably I have corrupted the configuration moving manually the images of the megadrive.
                      Thanks guys
