      (too bad, windows batch)

      There seems not to be some suff on the Retropie Forum.

      That is the batch that I had seen, yep. Sorry that isn't useful to you.

      @Zering - I've managed to set up PC98. I have to go to sleep now, but I managed to get Rude Breaker to work. It was an absolute punt actually, I had the four BIOS files but none of the hashes were right, and I couldn't find the .wav files anywhere (I don't know if that will cause me problems with some games). I really didn't expect the system to load at all.

      So it works! My controller didn't, so I need to look at that. I'm not sure how to map it, and the game was running slowly but you mention somewhere above about a setting to sort that out.

      I'll have another look tomorrow.

      Edit: Oh, do .m3u files work with the PC98 emulator? They aren't listed on RetroPie wiki but then that doesn't mean they don't work.

        I prefer a bash, but if that does not work, we can always try that batch. Lateron I was thinking that batch can also be run within the dosbox. Perhaps a solution.

        I've managed to set up PC98.

        Perfect.

        I couldn't find the .wav files anywhere.

        These are "YM2608 (OPNA) rhythm samples", I think.
        Hope It's helpfull.

        Edit: Oh, do .m3u files work with the PC98 emulator?

        Not mentioned in both docs. We will have to try.

          Thanks, @Folly

          I will try on the .wavs with that then, and I'll give .m3u a go.

          All games apart from Rude Breaker seem to be giving me a Japanese "Please set the system disk" message... Do you think that relates to my BIOS being wrong or is this something you've encountered?

            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 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".

                        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?

                              Could you go into your RetroArch menu and check under Directory/System Bios to see where the emulator is actually looking?

                              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?

                                  @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.

                                          @AdamBeGood What file type are you using and what game are you trying to play?
                                          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 ......)
