You can do something about it
I have not found a satisfying solution yet, but I am at least able to enter some commands, after starting dosbox with the option -startmapper and using the keymapper application which is started using this command.
It needs some time to learn how to use it, though.
This generates a file "mapper.txt" in the current directory.
Here is my mapper.txt:
Put it somewhere, then start dosbox from the directory where you put mapper.txt and dosbox will use that key mapping.
Also, if you always want to start the same program under dosbox, you can enter commands in /etc/dosbox.conf and start dosbox with the command
dosbox -conf /etc/dosbox.conf
Here is my example dosbox.conf (remove .txt): [ Invalid Attachment ]
Bul you will still need the correct keymapping in order to actually use the started program
Good luck.
And please let us know if you optimize the key mapping further.
