      @iandaemon I just posted a screenshot of my BIOS folder below. I thought I had the main BIOS files for the two main SegaCD emulators based on what I've read, but maybe not.

        @jmiller820 pretty sure the bios file names have to be lower case.

          @zering Just renamed them to be lowercase, but unfortunately getting the same result. BIOS Lowercase.png

            One other detail - some ROMS when I try to launch them just go immediately back to the games list. Other ROMS actually do seem to try to load but get on a blank/black screen, and are stuck there until I use the hotkey to get back to the games list myself. All of my other emulators and ROMs are working, so this issue is definitely unique to SegaCD.

              @jmiller820 what games are you running using which emulator?

                @zering Here's my ROMs list. I haven't done anything to specify which emulator runs which game, but my understanding is that it defaults to lr-genesis-plus-gx.SegaCD ROMs.png

                  @jmiller820 lr-genesis-plus-gx won't run the full Sega CD catalogue. It doesn't support CD32X games or multidisk games. Have you tried picodrive? That might partially resolve your issue.

                    @zering how do I switch it to run picodrive? I was aware of lr-genesis-plus-gx not running certain things, but I thought it would at least run SOME of my ROMs. It hasn't run anything.

                      @jmiller820 You launch a game, as it launches a small window will appear, press a button on your controller to open the runcommand menu where you can select a different emulator.

                        @zering Success! Haven't tried everything but picodrive is working on at least the first couple of games I've tested! So I guess my problem was specifically with the other emulator, or the BIOS for it.

                          @jmiller820 Probably both. Most of your roms aren't compatible with lr-genesis-plus-gx. Anyway, glad it's resolved.

                            @zering I really appreciate your help! I'm definitely learning as I go.

                              @jmiller820 We've all been there. As a matter of fact I had the same issue, I learned about BIOS because I wanted to play Snatcher on Sega CD.

                                @zering Snatcher is one of the games I'm looking forward to playing! Did an English language version of Policenauts ever happen? That's another one I wanted to try (I know that's for PS1).

                                  @jmiller820 Yes on PS1 and Saturn. You'll have to find a pre-translated ROM or patch it yourself.

                                    @zering found it and it worked! Now the only challenge will be finding time to try to play through Snatcher and Policenauts.

                                      @jmiller820 They're only about ten hours long.

                                        @zering Ten hours? I've been finishing Snatcher for twenty years. XD

                                          @iandaemon I was all excited and optimistic that I could realistically get through them soon, and you just snatched (pun intended) all that hope away from me.

                                            @jmiller820 I could see why Snatcher might be tricky to finish, but Policenauts is fairly easy and can be beat in a day.
