Its good for 9.0.0 if you have an entry point. Ipatched switches current entry point is 4.1.0 (released) and up to 7 (not released). Not sure about 8/9.@ZachyCatGames
from what i read atmosphere is good to go on 9.0
Older switches can run cfw on 9.0.0 through FG, which is unpatchable on the older model.
If you have ipatched switch at 9.0.0, then your options are: wait for new hacks, or find one yourself.
