NDS core recompiler option

Hello! I recently installed retroarch, and update desmume core with nightly build (by replacing existing file in "System apps - retroarch - modules’ with ifunbox). Am i doing it correct way? And, in “core options” for desmume i can only choose "interpreter’ CPU mode (though my Iphone 6 is jailbroken with TaiG jailbreak). Is there recompiler support for this core, and if it is, how can i enable it? Thanks retroarch team for Your good work.
