This is great! Thanks for this!

 

[ExploitJunkie]

Good Stuff! Thank you!

Noob question, it can dump games that were downloaded vía freeshopNX ?

 

[DocKlokMan]

The common ticket is used as a template to generate the ticket for Games/DLCs you have downloaded. No keys are present within that certificate, nor any valid signature data.

Interesting! Certificate too? https://github.com/CaitSith2/SwitchSDTool/blob/master/SwitchSDTool/Ticket.cs#L28-L58
I would assume that would be copyrighted? Unless these are generic certificates and I'm misunderstanding.

This but packaging to XCI!!! Still very nice tool, I love it.

That certificate chain was included with CDNSP. Every single ticket from Nintendo's server comes with it.

I dońt get it, does this allow you to use your very own purchased games in cfw and use them to play online from there?

That would not make any sense.
It dumps legally purchased games without the need to use Freeshop/CDNSP at all.

This was possible all the time, Switch doesn't make a difference between legit purchased game and downloaded nsp in CFW. But the ticket will match with a legit purchase, so probably no ban if playing those online.

Does this package the NSP with the updates embedded too? That would be most useful.

 

[caitsith2]

Updates are their own title ID on the e-shop, and for some poeple the they will only have the updates without the base game, as the base game is a physical cart.

 

[Bladexdsl]

nice now someone go buy all the eshop games and dump them all for the rest of us

And the DLC too. (Unlike previous platforms, EVERY DLC has to be purchased.)

best tool ever!
Finally I can backup Bayonetta I as NSP xD
and all of my other eshop games too
awsome work - thanks!

Does this allow for dumping NCAs without modifying them?

 

[caitsith2]

The NCAs are not modified by this tool, in fact, integrity is verified both after decryption, and during the NSP packing. The only thing modified is the ticket, and only in the cases where the ticket is console unique. tickets of game updates are left unmodified. Might add a feature to NOT modify the tickets even for the console unique ones. That however would produce an NSP that could only ever be re-installed on the same console that it was dumped from, as the title key in such tickets is encrypted with a console unique RSA key.

Also of note, is that NSP is just a container format, that contains multiple NCA files, one of which is a meta data NCA, the certificate chain, the ticket, and a human readable XML version of the meta data nca.

I think a "don't modify the ticket" is needed, since multiple people will dump their games but not share them.

(btw, just to be sure, is the nsp produced in the end a valid nsp if re-installed on the console it was dumped from?)

"traces of having ever run cfw"? Do you know the process of runing a cfw on switch?

Yes. I have access to the coldboot exploit and just turn on my Switch, going straight to ReiNX with xci loading, which is private for now.

Good news!
ty for your hard work!

 

[ernieshmitz]

for larger games already downloaded does this dump split files? hopefully we'll see some split nsps around so us fat32 dudes can install some big games once tinfoil works with them
