    DosBox tells me that CD0:/ doesn't exist.



    For me on os4 that part ok, it says it exists, just when I mount it and tried to do "Dir" in the mounted virtual drive I have the same issues as you show. But in any case it just about "/" thing at end. I created BZ on DOSBox-staging repo (those guys always help me with all the related issues with os4 port), and once they will deal with it properly that can be added in both our ports: https://github.com/dreamer/dosbox-staging/issues/223

    Hi All, i updated Dosbox jit to the latest SVN sources:

    Dosbox JIT

    - added 2nd overlay mode: "overlay2", this mode requires new powersdl.library (included in the archive), please check both overlay and overlay2 output
    - fixes for cdrom and track playing (using sdl_sound - it wasnt tested, so report if it doesnt work).

    - this version sadly still has some problems with speed, i got either 15.2 fps or ~24 fps, don't know why

    Looks like scaling to correct aspect ratio ist lost when going fullscreen? Or at least I am not able to get it right...

    aspect=true (also tried aspect=yes)

    Does not matter if I use overlay or overlay2. As soon as I go fullscreen the correct 4:3 aspect ratio is lost. In windowed mode everything looks fine.

    Also I am not able to set the keyboard to german layout correctly. I thought keyb GR 437 inside DOSbox would do it, but still Y/Z are mixed up. :-(

    Hi all !

    Maybe it would be interesting to check the SDL2 version of DOSBOX (dosbox-staging) ?

    https://github.com/dosbox-staging/dosbox-staging

    i say that because i see support of full OpenGL with SDL2, and MorphOS SDL2 support it.

    Many thanks! And have a fun vacation! :-)

    And thanks for your work up 'till now, the JIT-version sure does run a tad faster!

    @zukow: I see you updated your DOSbox_jit, thanks! Runs fine on my PowerBook G4 so far. Full screen aspect ration is still wrong though. ;-)

    I know, sorry. I completely forgot about it but it seems that dosbox jit guy (jmarsh) is working on JIT in dosbox so probably i'll make new version within a month (also with ratio fixed).
