      If you want to send me an email, look into my user info.

      Sadly email addresses are only visible to you.

        I tried to send an email but I get an error :
        The following address failed:
        SMTP error from remote server for RCPT TO command, host: user is over quota

        You probably have used all your space on the email server and maybe you need to clean it up.

              Can you do the same trick with moon[at ?

              Moonpat is a machine language game.
              It can be started in QUASI88 standalone with N-BASIC as bios.
              commands are :
              mon
              *L

              Only, it start directly after that.
              Can't push it to a disk yet because of not having the knowledge of all commands.
              Perhaps in the future.

              In lr-quasi88 it seems it only can detect disks, so no go here !

                @Folly Oh man, this is so tantalising! Quasi88 in Windows does nothing for me - after I type L I just get a flashing asterisk cursor, then a new line with a flashing asterisk cursor and an L, forever.

                quasi.jpg

                In lr-quasi88 it's the same except I don't get the second *L line.

                And I can't get mame-pc8801-cass to run at all, even though mame-pc8801-flop1 works for Galaxy Wars.

                    @Folly Brilliant, ta! That got it working in Windows, now to see if I can get anywhere on the Pi4.

                      I have found a java tool for converting cmt to wav files.
                      It's called pcm8001.
                      I have also found a java tool for converting wav back to cmt files.
                      It' called cmt8001.

                      You can find them here :

                      Tried a wav on lr-mess-pc8001-cass, sadly, could not get it working.

                          Blimey, I have NO idea what to do with that. It just brings up some kind of Java commandline window that tells me to type "OK" and then closes when I do...

                            I'm not really very sure of what they are :D

                            • we still don't know why ES_SYSTEMS.CFG thinks .N80 files are supported, they don't seem to be in reality.

                            • you did SOMETHING very clever to convert the Galaxy Wars .CMT file into a .D88 file that mame-pc8801 can read, but I'm not really sure what it was or how it could be reproduced, and it doesn't seem to work with machine-code files anyway, which I imagine most games are.

                            • I discovered, and then somehow lost, the ability to type quotemarks in lr-quasi88, but they don't actually help with tape loading so it doesn't matter.

                            • so far we haven't found a way to get Noon Patrol working on Pi (which is my main goal TBH), although it works on the Windows version of Quasi88. (I've contacted the author to ask if he might upload it as a .D88 file instead, but no answer as yet.)

                            • you've found a file that converts .CMT files into .WAVs, but I have no clue how it works and it doesn't seem to produce runnable files in any case.

                            Is that a fair summary of where we are? :D

                              Yea, nice summary, looks like we did not get far. haha ;-)

                              I think we have to keep on digging.

                              I found an quasi88 for sdl2 and have succeeded to compile it on debian 11 on x86_64.
                              Will try that on the RPI4 too, and hope I will get it fullscreen.
