PPSSPP iOS Port

NativeApp, EmuScreen and zip_read are duplicates. You can use the existing files.
I know it's weird that those UI files are under the 'android' subfolder but every platform is using them.

Also, I thought iOS uses 114x114 icons? Blackberry and iOS should be able to use the same one for that. Otherwise maybe the Android icons. We can stick these in a common place if they are all being shared around.

You probably want a single main file (ViewController.mm?) that hooks in to everything (the Objective-C one). This should go in the native submodule.
Then all the other files are just xcode project files I guess. They can be generated by cmake (and then you'll have all the stuff like c++11 auto set which should solve the remaining errors?).

iOS FBO is same as Blackberry one so that codepath should technically work. Will need to debug that if it's still having issues.
