There is a new 3DS homebrew exploit from 3ds Developer MrNbaYoh who has released basehax one week ago-pichaxx. It is also an 3ds exploit via 3ds game Pokémon Picross.
It is also a secondary exploit which means you need to own a primary exploit which can access to homebrew launcher. The video on MrNbaYoh’s twitter shows that the exploit can be trigger successfully. Accoding to the comment in the twitter, the expolit can work on 11.0.
This homebrew launcher has not been released now and you can download the Pokémon Picross. As it might be removed by nintendo team when it is released publicly.
