OneChipMSX Releases

This page will hold releases of the OneChipMSX core.  Binaries will be available for at least the Turbo Chameleon 64 and maybe others, and source links will point to a suitable tag in the GitHub repo.

  1. Awesome work, thanks again. Just one question: would it be possible to save the settings? Changing the VGA mode on every reboot can be a bit tiresome sometimes:)

    thnx!

  2. Wow, I just noticed so nice the core runs on my cousin’s Chameleon , I wish I spent my money there instead buying the mist, as the 1chipmsx on the mist is limited and I cannot write on disk images and the sd card! so sad…

  3. haha , the SD problelm write is fixed but there is no mouse support on MIST, as I see on SYMBOS. But I don’t worry! I Just ordered a Chameleon and sold the crap mist, as its supported better as I see , thanks to you my friend!

  4. Hi Alastair, do you think it is possible to do some hack on the OCM core, so when a rom is loaded with Romload it is not necesary to reboot the Chameleon to extract the rom? that would be great. Thanks!

  5. Hello!

    I just installed the msx core on my mist and its very cool!
    Fantastic work indeed… anyway what is missing is the option to mount disk images I know we can mount via the incl. command, but I am talking about booting CPM for example and mount/dismount via the firmware menu.

  6. I’ve been having a lot of trouble trying to load multi disk games that require you to swap disks. I already tried all of the commands from msx banzai. But for whatever reason i simply cannot figure out how to swap disks mid game. I’m using the MIST board with the MSX core.

    • I’m not sure how to do this either, actually – how’s it supposed to work? If it involves holding a key down, I wonder if it has anything to do with USB keyboards on the MIST, vs. PS/2 on the original OneChipMSX? I will investigate when I have time, but unfortunately that won’t be soon.

  7. For some odd reason no matter which keyboard i use it would occasionally repeat key presses. i would usually have to reset the system to stop it. I’ve tried both of my wireless keyboards and my wired keyboard with a ps/2 to usb adaptor and get the same odd behavior. i have the latest firmware for my mist fpga board. Also for some odd reason the Caps Lock led on the keyboard doesn’t light up when pushing the caps lock key.

    • Thanks for the heads-up – I didn’t know about the new release. I will take a look at porting at some point, but can’t promise any particular timescales.

      • Hi again,

        I received my new mist this week but regretfully it does not work with the current port. It boots in dos but after that when accessing the disk I get read errors on A:. I found on a forum it’s a problem that multiple users have with a new type of mist. See here:

        http://www.atari-forum.com/viewtopic.php?f=101&t=30889&start=25

        Maybe when you look into the new Port you can try to fix this too?

        Best regards,

        Martin

        • This problem started happening with the SDRAM timing fixed for new board – but I think it’s just coincidence and the problem is a build-to-build stability thing. I haven’t found a solution yet, but will try to fix it in due course.

  8. Hi
    Thanks for all your work on porting these cores.

    Just a quick question, is the MIST rs232 port wired up for the MSX core ?

    If not, would this be possible ?

    Many thanks

  9. Hello, I’m very impressed with the MSX core, but I also have the same “access, disk read errors” as previously reported. Sometimes it will work, sometime it will not. It usually takes about 5x tries or more.

    Is there any way that you can address this issue? I’d be extremely happy!

    Thanks again for your hard work!

      • Hi AMR,

        First, thank you so much for your work and the ports! I’m using a MiST. I heard that the issue is because mine is one of the “newer” units which uses Hynix SRAM.

        Also, one small thing – I think the original MSX output in 15khz. Would it be possible to enable that in the core update?

        Thanks again and please feel free to reach out to me if you want me to test or need any other sort of information or assistance.

        Best Regards!

  10. Hi! What do you think to port KDL Zemmix Neo version to Mist?
    KDL is always updating it and I think it´s better than OCM (I am not sure).
    If you can, please, take a view about it and tell us what do you think about!
    Thank you for your job!!

    • I have looked at KDL’s version with a view to incorporating the improvements – it’s on my “To Do One Day” list – but I’m not currently putting any time into FPGA projects so I can’t make any promises about when or if it’ll make it to the top.
