      @jengun said in My last problem - the TRS80:

      No idea which CAS-file MAME is using, but this works with SDLTRS in Model I-mode ... in Model III-mode you have to type L after Cass? to select 500 Baud to load and save tapes for the Model I ...

      Job done! That generated a flickering asterisk readout at top right, and got the command prompt back when the tape was finished, then I watched the video to find out you need to (bizarrely) type / to start the game.

      Many thanks! Now I just need to get sound working...

        On the internet I see info of people using (binary files) :
        CLOADM

        You could try that.

          I see / doesn't work for EVERY game, so time to do some Googling. But other than sound that's the emulator figured out now, which is the hardest bit :D

            Yeah, I'm quite experienced with the Dragon/Coco so CLOADM was the first thing I tried, but I'll keep it in mind for other filetypes :)

              For these TRS-80 Models there is only CLOAD and SYSTEM ... no CLOADM ..

                @jengun Is there any significance in the fact that the asterisk readout sometimes starts with a C rather than being all asterisks? Those seem to be the games that can't be started with /.

                  You can convert and test things on :
                  https://www.my-trs-80.com/cassette/

                  I downloaded the manual of the model 3:
                  If it asks for Cass ? press L or H for baudrate :
                  You can press enter for the memory part
                  then do CLOAD
                  then do RUN

                  Here you can test on the website :
                  Press on C-1-1 and choose Emulator (reconstructed low speed) :

                  Type the commands and enter :

                    I've stumbled across the fact that sometimes you have to type a name rather than S. For example, for Meteor Mission 2, if you type METEOR the game then starts with /.

                    I have no idea how you work out what the name should be, because Meteor Mission 2's filename is actually METEOR2.CAS, not METEOR.CAS, but at least it's a clue... :D

                      Never used these computers.
                      Just learning too.
                      I haven't used filenames yet.

                        C means Checksum Error: In the "old days" this always happened shortly before the loading process was finished: some say that the emulator does this too ... ;-)

                          Oh, I'm getting the "Initializing" crash when I try to load DSK files - looks like I'm missing a BIOS somewhere, but the Retropie docs only list level1.rom to level4p.rom, which I have.

                          (I have the NEWDOS disk, but no idea how to get the machine to boot with it.)

                            I tried enabling floppy drives in the MESS menu (they're off by default), but all that does is make the machine say "Diskette?" instead of "Cass?", and no key seems to do anything at that point.

                              You should tell which system you are using because otherwise people can't help.

                              I tested .img discs on trs80m2, they autoboot.
                              trs80m3 didn't work with .img discs, as it misses a bios rom and there doesn't seem to be a "good dump" of it.

                              trs80m2 with lr-mess booting cpm22.imd :

                                @folly I think the real problem is that there isn't a single word of documentation anywhere about what's supposed to be in flipping "trsdos.zip". I've tried a whole bunch of files in various formats that are supposedly NewDOS, but I've got no idea if they're what the emulator wants. What's actually inside yours?

                                  In my last post I run CP/M 2.2 .


                                  Indeed not much info to find.

                                  Well the SYSTEM part I seem to get.
                                  But how does one know what the filename is ?

                                  It seem with this tool you can convert and get info out of the cas files.
                                  https://github.com/lkesteloot/trs80/tree/master/packages/trs80-tool
                                  But the tool doens't work on the RPI4.

                                    @folly I think I give up. It's just too hard trying to piece together half-fragments of information. I just want someone to tell me "Put this BIOS file here." And I don't know where to even start on making the sound work.

                                      (With the SYSTEM thing the MAME softlist filenames seem to be mostly accurate. The exception is where you have things like INVADE2, INVADE3, INVADE4 for lots of similarly-named games, in which cases it's nearly always just the INVADE part without the number.)
