Well, I tried version 5.24 and yes, 3DS games with EMU Libretro work!
The truth is that they are quite slow, compared to the Win7 version of CITRA, but I guess what will be missing now is to configure it well.
Right now I am downloading, out of curiosity, BATOCERA Plus. I'm interested in Windows games. I want to use my Pinball buttons with BATOCERAAA !!
Thanks to everyone.
