Games are not ported to PC.
Think of it like this. Games are written as modules. So you have modules for the sound, modules for the graphics, modules for any menus etc. Then you write the code that executes them and you compile it. That's about as simple as I can make it.
So just because they may use elements of a console game to create a PC version doesn't mean there is any 'porting' going on. In fact, porting is probably the absolute worst word you can use because it's completely incorrect.
Try 'compile'.
