Is it possible to develop a wine core Wine is written in c and libretro api too So if it is possible so it may be complicated So i want to develop it Can someone guide me basics to build it
Not really on its own, but something like BoxedWine (http://www.boxedwine.org/) could maybe be possible.
You would need to find its main loop and wrap its functions in libretro functions to generate a frame of video and accompanying audio files via retro_run().
I have summited issue here
