Wolfenstein II and Octopath traveler , should i redump the keys ?Not gospel knowledge, but I'd say bad dump. What game is it you're trying to install?
It either might be a bad game dump, missing keys, a new game that's not supported by 4NXCI, or all of the above.Bad NCA when trying to install says to me that it's a bad game dump. I would use a search engine and find some keys from somewhere and use them, attempt to convert and try again, but !(I might be wrong) you'd be better off trying to find another dump, NSP style.
Well xcis fail because of the people who made them. Most that fails are done with an old version of NSCB or people using the wrong keys, the good thing is that the app itself has a function to verify the files you made to prevent that. There are rare instances of people using bad files though.Most people like XCI as it'll contain patches and DLC, so they don't have to go hunting. I prefer the hunting, as I've tried many XCI fails but hardly any NSP fails... Each to their own with no right or wrong way of doing this I guess
NSCB can also add all files into one nsp deleting tickets or respecting them, you see them less becuase those are only supported by Tinfoil\lithium from blawar (tinfoil.io) and Rommenu (The installer from the gallery from SX OS), goldleaf and old tinfoil from Addubz don't support multinsps, that's basically why people make less of them.I use XCI because it contains everything like @Pinkton said , it is the only reason ,NSP file are harder to find in one file , I don't like downloading 15GB 1GB at a time , it is really annoying.
