Its no good. We don't have the proper tools to convert a .NCA into a .NSP which is what is properly supported. You will need to use one of the CDNSP downloads to grab it from Nintendo and have that tool convert the downloaded .NCA files into .NSP. To prevent yourself from getting banned using one of those programs, utilize one of the Switch certificates floating around the Internet that others are using with these tools. Those certificates as well as info on where to look will sadly not be provided on this site.
Yeah i use the CDN, but that gives me the nca instead of nsp, while with another backup game it gives a proper nsp.
I will check into it again,thanks for the quick reply!
@Skittyusedcovet thanks you as well
