      @ecto As you're a bit of a PC98 pro, I don't suppose you have ever encountered the issue I'm facing.

      If I open any .hdi file, I get a "How many files (0-15)?" message and then whatever I put, I get dumped to a Basic prompt. I've found floppy disk images to be fine (.hdm and .d88). It would be good to know if you have any thoughts on this - but no worries if you're busy, etc.

        @AdamBeGood .d88? That's a PC88 file extension isn't it?

        I'll have to check for the font.bmp. I'm hoping you're right. I really want to play the six Farland Story games.

          Oh hey, I just now realized this thread existed!

          I've always had a fascination with Japanese home computers, mostly because they seldom get mentioned in retrogaming circles compared to the usual home computers.

          Admittedly I haven't actually spent a whole lot of time actually playing anything released on them, but I'll still try to answer whatever I can.

          It was originally intended for the PC88, but .d88 isn't exclusive to it.

            @SuperFromND Well this thread has only existed for about three days so you're not too late to the party!
            I'm not much of an expert myself, outside of the X68000 and the MSX my knowledge is limited. But at the very least those systems are intriguing.
            Now that I've got the X68K and the NEC PCs pretty much sorted I think I'm going to look into more obscure machines, like the FM7 or the Sharp MZ700. The fun never stops ^^

              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:

                @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.

                                Beware, there are different checksum :

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

                                        @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?
