@SomeGamer post, to use 3dsx homebrew, you'll be launching using this in the sysnand
https://github.com/yellows8/hblauncher_loader/releases from your homemenu (just install the CIA, install the homebrew launcher starter pack in the SD like normal)
Homebrews in CIA form you continue using the same way you always used.
Long version:
People who are already running CFW, especially Luma with A9LH have no reasons to worry about homebrew breaking due to updates (the environment is patched to allow homebrews already, even in newer versions of system), that's why hblauncher and CIA continue to work.
People who are running CFW without A9LH normally use 9.2 sysNand version with updated emuNAND, in this case the homebrew launcher is started by the outdated sysnand, so they aren't affected by updates too.
