I think it is my fault. I made development easier and I used android libraries in many corners of mdosbox. And this must be replaced, the amount of work may be not worth it. Google made perfect libraries which significantly accelerated development and I could focus on what I wanted. If I should program all stuff at my own then I don’t know. Like my dungeon mapping tool 🙂 I do all from scratch and after 4 years it is not finished.
