      @AdamBeGood

      I think we actually don't need .m3u files for PC-9800.
      Most games are on harddrive images, you know.

      Yeah, I have Puyo Puyo on 2 disks - but I think I can find it as a .hdi

      Good thinking.

      I have the .wav files, now I need the proper BIOS with the right hash. Weird that Rude Breaker still worked though.

      Edit: .wav files don't have correct checksums. I may cry.

        Wow, so much to catch up on!
        I find that PC98 roms are mostly .fdd actually. They're a bit of a pain, but .fdi and .hdi games seem to work out of the box on my end. I think Rude Breaker is probably the easiest game to set up.
        PC98 on RPi has a lot of issues. For example, my .fdd files do not appear in ES unless I scrape the whole system. More importantly, and this is something I was going to open a thread about soon, translated games do not seem to display any text. There are a lot of games that seem great that require a translation patch, ie. the Farland Story games.

        @AdamBeGood Please share your .wav files checksums. The issue may be entirely unrelated. Like I said, PC98 emulation is tricky and there is very little information.
        I do not believe .m3u files work. When I tried, it didn't work, but that was ages ago and may have done it wrong.
        To suppress the slowdown in Rude Breaker, you will need to set the CPU Clock Multiplier high. 24 did it for me, but for some games, ie. Flame Zapper Kotsujin, you may need to set a much lower value.
        I believe mapping the controller in lr-n2pkai is as easy as going into the RetroArch menu and switching a setting in the Options menu. I don't remember which one but I think it's fairly self-explanatory. Many games require a keyboard and mouse though.

        Edit : @AdamBeGood My .wav files do not match the md5 checksum indicated by the documentation. Try them anyway!

        @Folly Thank you for all your help with the .m3u files! I'm just catching up after a long night, but I'll look into it this week and let you know how I get on...

          I've just typed those out as I couldn't think of a better way of doing it that would be quicker than me just getting to typing...

          I sorted out the joypad issue now, thank you. Yet to get any game apart from Rude Breaker to work though...

          Fair enough on the .m3u issue. Most games don't seem to need it anyway, and I saw there was an in-game menu so maybe swapping disks is possible there if we did need to play a multi-disk game.

            @AdamBeGood I've got the same sums. Can you give us more detail about the Issue? File types, screenshot, anything like that?

            Where is lr-np2kai looking for your bios?

            Edit : I may have misspoken, I'll double check my sums in a sec.

              Cool, let me know. So far as I know it is looking in RetroPie/BIOS/np2kai. It has certainly created an np2kai.cfg file in there.

              I get the CPU - High and then Memory lines on a screen, and then a black screen with Japanese text in the centre, which translate on my Google app as "Please insert the System Disk".

                @AdamBeGood Here are my checksums :

                So our files don't match but given that my checksums don't match the documentation and that I've still been able to run a bunch of games, I doubt that this is the issue.
                Could you go into your RetroArch menu and check under Directory/System Bios to see where the emulator is actually looking?

                  I see, I have to do my homework better.
                  I was too fast with my answer. Will have to look at all the files. Pfff... many.

                      It just has /home/pi/RetroPie/BIOS listed... Should I be amending that to /home/pi/RetroPie/BIOS/np2kai or is that correct?

                        @AdamBeGood You need to amend that to np2kai, yes.

                        I looked into the issue of japanese text/translated not appearing in lr-np2kai, and it seems it is a known issue. The font.rom in BIOS/np2kai should enable the text to appear, but for some reason that function in the libretro port of the emulator is broken.
                        Text does appear in np2pi but the screen is all squeezed in the upper-left corner of the screen, and I can't get it to unsqueeze in emulator, so I'm looking at editing the config file or some such directly. Problem is I can't find it. @Folly Any ideas?

                          I've put in some other BIOS files now, and I am getting a "How Many Files? 0-15" message, and then whatever I enter, I am dumped into a PC-88 Basic command prompt. Sigh... I will try some other files.

                          Interesting on the translation side of things, I did see some games I'd like to translate already - Rusty, E.V.O.

                            @AdamBeGood did you ascertain that your previous bios did not work by amending the directory in the retroarch menu?

                              Yep, I tried that. The result didn't change - service disk message. I am really racking my brains to try and work out what I am doing wrong. I've tried a lot of files now. Maybe I'll have a break and go back to it later.

                                  I'm thinking now if Rude Breaker runs maybe it's not even BIOS-related.

                                    Well, I'm still busy with other things. Just referring to the few games I have tested. (13cm ......)
                                    I do not have Rude Breaker jet.

                                      Here is my first attempt for creating m3u files automaticcaly.
                                      Go to the /home/pi/RetroPie/roms/pc88 directory :

                                      cd /home/pi/RetroPie/roms/pc88
                                      

                                      If your files are in a subdirectory for each game, it will find the games and make a .m3u file in that directory.

                                      This is the 1 line command :

                                      create_m3u=$(ls -d */ |  sed 's/\///g'); echo "$create_m3u" | while read line; do echo "making $line.m3u"; cd "$line"; ls *.d88 -w1 > "$line.m3u"; cd ..; done
                                      

                                      edit (explanation):

                                      • it gets the direcory's names
                                      • replaces the "/" in the output
                                      • puts the directory name into a string
                                      • echo's it and reads every line
                                      • goes to every individual directory
                                      • reads the disk files in that directory
                                      • uses the name of the directory to make an .m3u
                                      • puts the info in the m3u file
                                      • returns to it's original directory
                                      • until it has done every directory

                                          My advise, try it first in a separate test directory with just a few games in it. See what happens.

                                          If you want an explenation on how it works then I can add that ofcourse.

                                            @Folly Do the games need to be in separate directories?
