      So after a few months of test and for test who played Dreamcast a lot or tested a lot of different games, what is the preferred format :

      • CDI seems to offer the best compatibility but it is a degraded / compressed format
      • GDI is a full 1:1 format accuretly dumping the game but the compatibility with current emulator isn't very good
      • CHD is compatible with the emulator but people doesn't mention it very much : when converting GDI to CDI is the compatibility as least as good as CDI ? also can you convert ISO (which aren't compatible with the emulator) to CHD ?

        I suggest converting gdi into chd. Cleaner and smaller than gdi and without the downsides of needing to manage multiple "Track 01" files.

        Google gdi to chd converter program.

          @dh04000 yeah I know that but how does the emulator handles CHD files regarding compatibility ? is it at least as good as CDI ?

            I would say its the same as non converted GDI.
            Tested a few games which are in the compatibility list marked at "not working GDI".
            Also tested only with v4 CHD files (v5 untested).

            EDIT:
            Have you only a .iso file or with an .cue?

                You are asking in your first Post:
                ....also can you convert ISO (which aren't compatible with the emulator) to CHD ?

                Thats why i wrote about that 😉

                  @abunille oh yeah sorry forgot about that.

                  Well I don't know, I just see full romset of iso (I assume with no cue) so I wanted to know if you could convert that to CHD

                    .iso without .cue i dont know.
                    With .cue beside the .iso you can "try" chdman (before version 0146, with 0146 comes chd v5).
                    Create a batch file and try this command inside:
                    for /r %%x in (*.cue) do chdman -createcd "%%x" "%%x.chd"

                    Better way is to look for an alternative source
