    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).
