Thanks Hayato for the answer, so is safe update sysMMC, and consequently the emuMMC with daybreak, to 16.0.2 and then update deepsea as I always have (with 1.5.1 of course)?
Thanks for the patience, i'm pretty sure that I'll ask for banal things.
I have always used Deep Sea but the last update I did was the fw 14.1.2 atm|1.3.2E using daybreak after the dump of the sysFW. The new release of DS supports until fw 16.0.0 but che currenty official fw nintendo is 16.0.2...
