Old Midi Device file .dev extension

Hi,

maybe one of you can help me out. I found a very old device map for my old Kawai K5000. It came as a .dev file, it also included a .d file, which would be the source file for a tool called DMaker, which I never heard of.

Is there any way to convert, export, import such a file into the recent Cubase version?

Thanks fpr your help.

Peter
