Thanks. I'm sure people with dev units will be happy for these. I would've liked to look into these and compare them to the retail versions. But after removing the CIA crypto, I've found that all the NCCH files use secure crypto. (I was hoping that since early dev tools were zero-key crypted, maybe these would be. But nope.)
Comparing exefs/romfs hashes let you find the ones Nintendo made different. For example Mset in 6.1.0 has the same exefs/romfs as retail.
It'd be fun to make an emuNAND with these and have some insight as to how the development apps work, but since these are signed for developer consoles, they'd never be installable on a retail system. Not to mention, if something like this were made to be installable on a retail system, I don't think that'd be a good thing.
