There's really no reason to up just for a game. CFWs by nature have 100% perfect ROM compatibility, even dead CFWs like RXTools still has that much going for it.hope we see an update once new firmware is out when pokemon moon/sun is released
By real suggest of instead of waiting around for an unlikely update, is to either to stick with ReiNAND or switch to something else. Regardless, you are most likely not going to start seeing updating for ReiNAND, unless someone else picks up the project.
