      I've been tinkering on the PC98 again this morning.

      It turns out if I remove all BIOS from the folder, then the floppy games I had running previously still work! The difference is that if I put the BIOS back in, then I begin receiving "How Many Files?" messages for .hdi rather than blank screen, which is what I get without any BIOS at all.

      Here's the screen:

      https://flic.kr/p/2k3C9kD

      I still think it likely that I have the wrong BIOS, but I also find it surprising that none of the ones I've tried have worked. I have tried a lot now. Here's me going through BIOS checksums yesterday:

      Here are runcommand entries if that is at all useful.

        @Folly When you say 'changed a few', do you mean that you've replaced the file entirely or that you've somehow edited the md5?

        Edit : Got it! My N88.ROM was way off.
        As a note, n88jisho.rom is still wrong on my end. But Final Crisis plays fine. That file seems to be optional.

        Thanks again @Folly !

        Good job!
        Yes, I meant replaced a rom or two.

          @Folly That's excellent news!

          Makes me wonder if CD and HD images can also be added together with FD images. All together in 1 file.

          You can mount different types of images together using one cmd file (a little like a m3u file. Read here.

          Thanks for sharing !
          Will look into it later on.

            about your logs.

            If you want a good log, then you have to start a game and directly press a button when the load screen from retropie is on. Then choose "launch with verbose mode". then afterwards you will have a good log file.

            Will catch up, with you all, later on. Duty is calling.

                I was checking against your sums yesterday - from higher up in the thread. I can't find them, I am not sure what I'm doing wrong. I haven't tried today. Irritatingly, I have to produce a spreadsheet for work so I can't trawl through BIOS right now.

                  @AdamBeGood I completely forgot I'd already put them up.
                  Well I'm sure we'll figure out the problem eventually. To be honest I'm starting to think I spend more time tinkering on my pi than actually playing it ^^

                    I was looking through the RetroPie/RetroArch BIOS packs, and tried all of those I think. I really don't get it.

                    @Folly Hope duty goes well. Here is a verbose log: https://pastebin.com/kJz5Grum

                        Beware, there are different checksum :
                        sha1sum
                        md5sum
                        crc32
                        etc

                          Yep, initially installed from binary and then when it was going belly up I tried to install from Source.

                            This is what I was asking last night! I said I was using sha1sum. Are you going to tell me that isn't what I should be using? Arggggg.

                                @AdamBeGood Yeah it's a md5sum you need to be looking for.

                                Now I'm wondering if I gave you the right sums...

                                Sorry ^^

                                  It's my fault for not pursuing this! At this point, my .roms are the same as yours that you listed yesterday apart from font.rom. Yamaha files are different.

                                  @Folly How do you mean filenames are bad?

                                      @AdamBeGood Your font.rom is different? Are you getting any japanese text in, say, Popful Mail?

                                        It might be just as likely to be the font.bmp, but yep I do get text in text boxes in that game. That is one thing my PC98 can do.

                                        Edit: Yep, it's the font.bmp file. I just deleted all my BIOS, loaded the game. No text. Just copied over font.bmp, there is text. There is a text.bmp file in one of the RetroPie BIOS zips I think.

                                          @AdamBeGood Some games have text, you might have been lucky.
                                          All the games that depend on the FONT.ROM to output text have been broken on my end.
                                          When you're free any chance you could check a couple for me?
                                          I've looked into the font.bmp, it looks like it's an anex86 bios.

                                            But it has to be that FONT.BMP on this game! When it wasn't there, there was no text. When I put it in to the folder there was text. There was never a FONT.ROM to make the difference.

                                            Have you tried putting it into the BIOS folder just to see?
