Save games should be stored somewhere in the directory where
you installed the game to. Assure that you really installed the game,
and that all files in that target directory are accessible (no read-only
attribute at some file).

Thank you. I solved the problem already. The Mistake was mounting the main game directory "discwld.cd" itself as the harddrive C: as discribed in the readme file of Dosbox (may be I missunderstood something).
There fore the game was searching a subdirectory named "discwld.cd\save" in the DOSBOX drive C: to save or restore game situations.
But because the drive C: was already the directory "discwld.cd" for the game there was for shure no subdirectory "C:\discwld.cd\save".
I simply copied the complete "discwld.cd" directory into a directory named "Games" and mountet this directory as a harddrive in Dosbox. Now it works pefect.

My current syntax in the batchfile (dosbox_discworld.bat) starting the game is:
dosbox -c "mount c c:\games" -c "mount I W:\ -t cdrom" -c "C:" -c "cd discwld.cd" -c "disc" -exit
("W:" is my DVD-Drive)

Right, in general it's best to have some directory on your hard disk
mounted as c (like "mount c c:\oldgames") and install the games
there. This way they can create the save games etc.

If you think some part of the readme was unclear/could lead to
misunderstandings feel free to tell or rephrase that sentence(s).

Hello wd,
I think, unclear is this part of the readme I followed first:
"dosbox c:\atlantis\atlantis.exe.....This mounts c:\atlantis as c:\ and runs atlantis.exe."

I think, this syntax caused my problems, because it mounts the main game-directory as the c-drive. But with Discworld it does'nt work.
May be this syntax causes also problems with other games. I don't know.
But I think, it will be ok pointing out this issue in the readme file.

EDIT:
You did a great job! My wife played discworld about 12 years ago and she loved it. She whanted to play it again since a couple of years, but I never could bring it to work with sound. You must know: Without sound this game is less then the half fun, because Eric Idle from the Monty Pythons is speaking the main figure Rincewind. And he does it in his own special funny way. If you ever played this game hearing his voice, you will never miss the sound.

So thank you very much. You gave us the way to enjoy this old highlight again.

ah, I see where you got on the wrong way. The example really should be rephrased. It's just meant (as far as I can see) to show what you can do with the command line. But as it is written BEFORE the mount command is explained properly it can cause problems.
And yes, mounting the game folder as C:\ is problematic and shouldn't be done 😀

"mounting the game folder as C:\ is problematic and shouldn't be done"

I think, this phrase should be overtaken into the readme.

Already there:

Mounting your entire C drive with MOUNT C C:\ is NOT recommended!

I'll have a look at that example you mentioned by times,
thanks for pointing it out.

@wd

Mounting your entire C drive with MOUNT C C:\ is NOT recommended!

is not the same as

mounting the game folder as C:\ is problematic and shouldn't be done

😀
It's a common error here that people mount the game folder as c:\ (e.g. C:\Atlantis as c:\ or C:\games\atlantis as c:\) and it's one of those things people get asked to correct first before the community further trouble shoots.

Erm sorry, didn't read your posting close enough.
Maybe this can be added to the mount and troubleshoot sections, too.
