@Teroyk: checked the Hatari page. There is very good documentation how to set it up and make gmaes playable. It is just that I am lacking (still after using linux over ten years) some basic knowledge of making directories and extracting files to right places etc. so even though the instruction are good I don't have enough knowledge to be able to follow them without getting too much anxiety and stress (which I have to avoid at the moment).

I have now watched many "100 dos games in ten mnutes" youtube videos and made lists of what seems good. Maybe I try to hunt those down and then try to get them running on dosbox.
