I can't find a way to invoke the keymapper in the high resolution compilation h-a-l-9000. No by the hotkeys nor by parameter at startup (-startmapper).

One way I got to overcome the problem is by setting a second DOSbox with a previous compilation,that does not include the cool high resolution modes of h-a-l-9000, in a different directory, invoking the keymapper, making all the changes I want and then copying the produced file "mapper.txt" to the High resolution DOSbox h-a-l-9000 I use.

A second way is directly editing the "mapper.txt" file by notepad (once I got the file)
