The libretro Citra core has compatibility issues, input lag problems, and requires OpenGL 3.3+ (which not all Android devices support consistently). As of 2025, there are no official plans.

If you are deeply attached to Lemuroid’s interface, your best bet for 3DS is to switch to a dedicated emulator like Lime3DS or Panda3DS and use a frontend like Daijisho to unify your library. Daijisho can launch 3DS games through Citra while still looking like a single console dashboard.
