Anyway, about actually porting things you should really talk to us first. We're currently (well, semi-actively) planning how to refactor Dolphin's core into a library such that other projects can easily write a frontend for it. If you'd go ahead and write some libretro port of Dolphin without us telling, chances are you'd be wasting your time when you could just go the "easy" way once we have finished our refactoring.
No announcement yet.
