      Hello!

      I've been chipping away at trying to get Neo Geo CD games to work for a few days now but every time I make a little progress, I hit another wall. I've looked through the forum here and can't find an answer to my current issue.

      I have the Neo Geo bios (neogeo.zip) and the NeoCD bios (neocd.zip and neocdz.zip - both containing a file called neocd.bin) in my roms folder. I also have the following in my BIOS/neocd/ folder (though I'm not convinced these are doing any good):

      000.lo.lo
      front-sp1.bin
      neocd.bin
      neocd.srm
      neocd_f.rom
      neocd_sf.rom
      neocd_st.rom
      neocd_sz.rom
      neocd_t.rom
      neocd_z.rom
      ng-lo.rom
      top-sp1.bin
      uni-bioscd.rom
      uni-bioscd32.rom

      I have a couple of NeoGeo CD ISOs (.cue/multi-.bin) in my roms folder. When I try to launch one, use the lr-fbneo-neocd core, I see an animation of a spinning disc and then the Neo Geo CD logo. It then takes me to a GUI with a Game section and a CD-Player section. This is where I'm stuck. I can't click the "Start" button under the Game section. None of the buttons interact with it. I can click on the buttons on the CD Player side. Nothing really happens when I do, but I at least see the buttons reacting. The Start button does nothing at all.

      Can anyone pinpoint what I'm missing? I'm assuming my BIOS stuff is ok since I am now able to get to this GUI but maybe my ISO is bad? I've tried other ISOs that just bounced me back to EmulationStation so I'm not sure that's it either. Any advice would be appreciated.

      Pi Model or other hardware: Pi4 8GB
      Power Supply used: Argon40 3.5a
      RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.8
      Built From: Pre-made from Retropie
      USB Devices connected: One 512GB thumb drive
      Controller used: 8Bitdo SF30Pro
      Error messages received: None
      Verbose log (if relevant): No crash
      Guide used:
      File: (File with issue - with FULL path)
      Emulator: lr-fbneo-neocd
      Attachment of config files:
      How to replicate the problem: Described above

        FBNeo only supports single file MODE1/2352 cue/bin for neogeo cd, read this for more information.

        Those are meant for the other neogeo cd core available.

          @barbudreadmon Oh man, thank you so much! I had seen it doesn't support .chds but I didn't realize it also doesn't support multi track files. I'm going to follow this guide. Thanks again!

            @Ikyrus note that you might want to give a try to the other core (lr-neocd) if you want support for chd and cue/multi-bin, although i heard it has a few emulation bugs FBNeo doesn't have.

              @barbudreadmon Thank you but no need. The games I needed to run are all working perfectly under lr-fbneo-neocd after merging the bin files with CDMage. Thank you again, I really appreciate the help.
