If anyone wants to try to exploit it (I don't), Pokemon X/Y/OR/AS can be used as primary exploit games. DM me for details if you're skilled.

These games can be used as primary exploits, and most likely userland. Userland homebrew cannot be used to install B9S or CFW. Keep in mind that the games are not exploited yet, however they possibly can be in the future. Don't get your hopes up.
