Question

Software porting

Hello! I'm interested in the process of porting PC games to mobile devices. How this is all implemented, whether the source code of the game is used, I am interested in everything connected with this. Links to informative articles, as well as your porting experience, are welcome. :-)

Take and rewrite. Sometimes you can save on time (one architecture, one language, etc.).
You can’t call it rewriting from scratch, because there are still some resources that can be transferred. But in the worst case, it still looks exactly like this.
