      Did anyone managed to activate unibios on lr-fba-next?

      I edit /opt/retropie/configs/all/retroarch-core-options.cfg

      and insert the following line
      fba-unibios = "enabled"

      (as mentioned here https://wiki.libretro.com/index.php?title=Final_Burn_Alpha)

      After saving and rebooting lr-fba runs unibios, but lr-fba-next does not (rpi3, retropie 3.8)

      Any clue? Thanks a lot

          retropie 3.7 => lr-fba-next 0.2.97.37, based on mame 0.167

          retropie 3.8 => lr-fba-next 0.2.97.38, based on mame 0.173

          you are using an outdated neogeo.zip bios file

          get the one from mame 0.173 romset, it will work fine.

          it does for me.

            I can confirm this worked.

            I also had wrong version ROMs, which was preventing the bios from working, so I had to go find some of the recent versions. Will report back later once I've had a chance to install.

                Strangely even if I update the neogeo.zip file to the latest, lr-fba shows the unibios splash screen, while lr-fba-next doesn't. Are we sure that both emus read the same config file (/opt/retropie/configs/all/retroarch-core-options.cfg) and that both understand the fba-unibios = "enabled" option?

                  Yep! I got it booted in next.

                  I would bet it's a romset mismatch. I should be able to verify that this afternoon later!

                    unfortunately I don't think so. I have updated neogeo.zip and one rom (maglord.zip) to the latest and still lr-fba shows the unibios splash screen, while lr-fba-next doesn't :(

                      are you using neogeo or FBA versions of the roms?

                        mame ROMs. I have tried different sets, including split and merged 0.174. Always same behaviour. lr-fba works, lr-fba-next always loads the stock bios

                          Just to clear up things: both lr-fba and lr-fba-next do work, but with the fba-unibios = "enabled" option, only lr-fba shows the unibios. lr-fba-next keeps on working, but with the standard bios.

                          If it was a ROM mismatch problem, I think lr-fba-next wouldn't load at all. It seems to me lr-fba-next doesn't recognize the fba-unibios = "enabled" option. Is that possible?

                          I can post the configs if needed

                          Thanks a lot guys

                            Mine is working intermittently. For instance, WindJammers shows the unibios even on next.

                              Tried Windjammers. No luck: lr-fba-next still loads the stock bios...

                                Yeah it's weird.

                                  Could it be a bug? In that case I'd report it to the Retropie dev team. Please let me know if your tests confirm my findings, so that I can file bug report. Thank you

                                    Solved!

                                    It seems that lr-fba looks for the bios under /home/pi/RetroPie/BIOS while lf-fba-next looks for it under /home/pi/RetroPie/roms/neogeo

                                    I have updated both dirs with the latest neogeo.zip and now the unibios splash screen is showing on both emus

                                        Ok, so I tried that and no luck for me.

                                        My bios, when unzipped, has up to 3.1 unibios? Is that the right one?

                                          Have you added fba-unibios = "enabled" to /opt/retropie/configs/all/retroarch-core-options.cfg ?

                                            Oh no, I just had it enabled in the gui you can pull up during games.

                                            I'll give that a whirl and report back.
