switch nsp to nsz

[lazo]

hello is it safe to convert my nsp games to nsz format with sak software

You can convert nsp to nsz if you want, only benefit for nsz is for storing it since it is smaller size than nsp.

it wont corrupt the nsp game when i convert to nsz
and do i use latest product keys and titles for using
sak and thanks for the fast reply

I would say it isn't safe to run ANY .exe from github, that both warns you of "false positives" and does not provide the source. But that's just me.

As for the keys, you should always use the latest for maximum compatibility. Games that come out months after the latest firmware, will generally require the latest key to decrypt...

nsp and nsz are just containers. Think of them as zip and 7z files, if you will. Same content, but nsz (and 7z) compress better. Nsz files can be reversed back to nsp.

Just to clear a misconception. When you install a nsp you just unpack the nsp and it gets installed how Nintendo do. But you dont have a nsp file installed per say.

XCI should be converted to xcz, and nsp to ncz - they are just compressed and get decompressed during install so it makes no difference as the decompressed installed game is an exact byte for byte copy of what you would have had if you just installed the nsp/xci. All converting does is to save disc space and to make if faster to transfer the game to your switch via wireless or USB etc.

When I using Sak to compress a nsp to nsz I don’t notice that much of a compressed file I’m trying to like get more disk space on my hardrive can I also somehow use winrar or 7zip for make the new nsz file compressed even more into a rar or 7zip file like I might have a 6gb nsp game when I go to convert it to nsp I might get it down to 5.80gb nsz this is just an example

Yes you can "Zip" the nsz file, to get it a little smaller.

'A little' is probably key here. At this point the amount of space you save will likely be tiny.

Yup. You can adjust your compression levels in WinRar/WinZip/7Zip, but you still are not gonna get much smaller. Compressed to nsz is really all you need to bother with for space.

Compressing a nsz file to rar or 7z is useless. The compression algorithm of nsz is more efficient than both of them, for the Switch format, at least. You can increase the compression level up to 22 max. It takes longer to compress, but you'll know you can't compress any better. Not all games compress a lot. It depends on the kind of data. Read more about the options here.

BTW the optimal compression level for Switch is 19, 'cause at 20-21-22 lvls (sometimes..) it's required more than 1 GB of RAM with decompressing, so using applet mode for example is impossible while installing these nszs.

TL;DR always use max 19 level zstd for NSZ, only.

a question when i get any game then download it and unrar it and it has the title name
can i change it to a smaller name or whatever i like and then winrar the game
will it make that game not install or work cause i changed the original name
or best just leave it as is when i downloaded it
thanks

Won't matter if you rename it.

rar could be a little more but as the NSP file already have a sort of compression another compression will no provide so much space saving.

converting to NSZ can give more space saving because you are compressing the "original" files using another algorithm which could be more efficient.

Just wondering, but I heard rumors about that you shouldn't convert some DLC NSP files to NSZ files, like DLC unlockers. Is this true?

What compression rate should you use? Fast, Intermeddiate, Average or Hard?

I like the idea of compressing my files without having to pack them into zip or 7z archives, but I would like to know just how reliable the conversion tool (SAK) is. I'm currently on firmware 16.0.2 and can use lockpick rcm to get my keys, but I don't know what'd happen if I try to convert a file that let's say requires firmware 16.0.3 (unlikely, but hypothetically speaking). Do I get a clear error message to inform me the conversion failed or do I get a silent 'success' and a corrupted NSZ file?

Is not shouldn't than you really don't get any benefitsbecaise a 128 kb file will not compress more tha some few bytes

Sak uses official NSZ tool is only a GUI. You also can download NSZ from github if you really like latest one.

16.0.2 and 16.0.3 share the same set of keys
