      @mitu is there a way I could make sure before downloading if the ROM would work or not ? or is just random trial and error ?

        @obliv You can use something like ClrMamePro or RomCenter to validate your ROMs or get a correct ROM set for your emulator.

          @mitu said in neogeo ROMs do not load with UNIBIOS 3_3:

          ClrMamePro

          thanks, I will try. however.... I have downloaded previously a full ROM pack (almost 1 Gb). Is it likely they are all wrong ?
          Are you sure that the problem is in the ROMs ?
          I can try those softwares and validate anyway...

            @obliv I tried with Rom Center
            I was able to open a folder with the roms (182)
            they are "unknown" to the software...
            they do not seem to be corrupted (I tested them) and indeed they are working on my emulator on PC (neoragex).

            I also downloaded another rom pack
            same as above.

            I haven't tried to use them on RetroPie
            but I am suspecting.... the problem might be not in the ROMs... or what do you suggest ? :)

              I still suspect the ROM is at fault. Here's a log excerpt from launching Metal Slug 4 on my system - both ROM and BIOS files are in the same folder

                  @mitu mh... well how can I argue against this ? :) thanks for your help. I would then try to use the other ROM pack and see what happens. At this point is maybe better to test ROM by ROM...
                  Is there any way to save the ROMs I have ?
                  I do not know how strict this forum is but it would be helpful to use your ROM so that we can understand what is the problem...but of course I do not know if files can be shared here

                    @obliv As I said in the other thread, there's no ROM sharing here. Please stop asking and re-read the Forum rules. You can verify your ROMs using RomCenter/ClrMamePro - I guess you didn't go through with that - , there's no need to compare ROMs.

                    One idea - did you keep the names of the .zip files from the ROM set you downloaded or you renamed them ? My ROM zip is called mslug4.zip, yours appears to be named metalslug4.zip.

                      @mitu sorry. Thanks the new rom works and is called like yours. Thanks again ! :)
                      I did check with Rom Center yesterday though. It did not prompt me any error about those ROMs. That is why I still had the doubt. I will simply replace the ROMs. Thanks again !! :)

                        @obliv never rename arcade / Neo Geo roms. They won’t work if you do
