      Hello. I Have problem to run mulitidisc game on lr-px68k. When i run the game i have black screen and my gamepad non stop rumble. When i hit f12 i see two floppy disks in drives fdd0 and fdd1. I must go to retroarch/quickmenu/disccontrols/eject disk and currentdiskindex change to second disk and insert disk. When i do this steps game runs. i checked m3u files and try different roms and different bios in karopi folder, i tried reinstall emulator from source- no results. Not all games will not start, but most of them. I have Rpi4 with retropie 4.7.19, lr-px68k 1.9.7(0.15+b309941).
      Could someone help? Thank You.

          Can you post your .m3u file ? Maybe the order of the disks is switched in your .m3u and the 2nd disc is the game boot disc.

          The rumble can be disabled from the core options if I remember correctly.

            @mitu this is definitely not a problem with m3u.
            I looked through this topic:
            https://retropie.org.uk/forum/topic/15551/sharp-x68000-multi-disk-games-questions/19?_=1641323868175
            and there one of the users had the same problem but I don't know what the solution is.

            @supercatfooz I have tried to use dozens of m3u based files for the games and whenever I launch I get the screen flash and then just a black screen. I have tried creating my own and also have tried ones premade I found online, but I just can't get these darn files to go. If I launch the first disc of a game they do fine. I am running RetroPie 4.4.2 as of commits a few days ago.
            

            The problem is with the second drive. When I remove the floppy disk from fdd1, the game starts. It looks as if the emulator does not know which disk to boot from.
            damepad shakes when the emulator reads a floppy disk.
            I will add that I wanted to check other roms and m3u files, so my friend sent me his m3u file and rom games that work on his emulator. His files don't work for me. There is the same problem.

              @krinasam Please post the .m3u file you're using.

                  I tried this game and it works fine with this M3U file. The games take a while to load before booting (not much, but noticeable) and shows a splash image. The rumble is just telling you that the floppy image is read, maybe you need to wait a bit more until the game loads ?

                  Note that you can 'overclock' the machine from the core options (CPU Speed) to speed up the loading. Try setting also the Save FDD/HDD Paths to off, so the core doesn't save the last loaded disc/hdd image.

                    @mitu The only way to run this game for me is to pull the second disk out of fdd1. (F12 / eject disk from fdd1 / reset). The game starts but it says there is no disk in the drive, so now I put a second disk in fdd1 and press R- the game starts. Or the second way: (retroarch / disk controls / eject disk / current disk index set to 2 / insert disk). The game starts immediately without any messages.
                    I don't know why this is so, I can't figure it out.
                    Many multi-disk games don't run properly.

                      I can't reproduce your error. The core will load the first 2 disc images from the .m3u into FDD0/FDD1, so the 2nd drive should already be populated with the 2nd disc image.

                      Verify that your BIOS files are correct (iplrom.dat and cgrom.dat), then remove the keropi/config file and try again.

                        @mitu Good news. The problem has been resolved. I have looked at the emulator documentation and it only needs 2 files cgrom.dat and iplrom.dat. In addition to these files, iplrom30.dat, iplromco.dat, iplromxv.dat were in the keropi directory. I deleted the last three files and everything works !!

                          That's strange, because I have those BIOS files present and there was not problem loading the game.

                            @mitu Slight correction. It is not the fault of these files. There was also a sram.dat file. I deleted the sram.dat file and it works the first time I run it. After the first run, this file is created again. Again, the game won't start
                            if I remove sram.dat I can run any multidisk game but only once. I removed all access permission in sram.dat. Now games always run correctly. @mitu can you show me acces permission in your sram.dat file? Do you know what the sram.dat file is needed for?

                              @krinasam There are no special permissions on the file, should be read/write by the install user (pi).

                              $ pwd

                              -rw-r--r-- 1 pi pi 131072 Jan  5 17:19 iplromxv.dat
                              -rw-r--r-- 1 pi pi  16384 Jan  5 20:59 sram.dat
                              

                              Can you describe, step by step, how you get to an error ? I'm starting to suspect that 1st run of the game is ok, but if you run a different game things change somewhere (be it sram.dat or config).
                              I have no issues running repeatedly the same game (Atomic Robo Kid), I'll try running a few other games also to see if anything changes.
                              Get a verbose log - as detailed in the docs - from the faulty run and then post it on pastebin.com.

                                @mitu If i set access permission like You the game could not run. I must remove read access permission to pi user and game runs correctly. All muli disk games work fine.

                                  Then something else is broken in your setup, the emulators (including RetroArch) should always run as the pi user, so read/write access for the pi user is normal.

                                  runcommand.log it is the same in both cases

                                  That's not the entire log, just the beginning of it. Use pastebin.com if you wish to post the entire file.

                                          Do you have enough disc space left on your sdcard ?
                                          WinSCP should be able to look/transfer the file, try doing it after exiting RetroArch.
