Homebrew RELEASE NSPatch - Patch NSP Files to their actual needed FW version

[adrifcastr]

THIS TOOL HAS NO USE ANYMORE BECAUSE TINFOIL CAN NOW IGNORE THE REQSYSVER UPON INSTALLATION!

So today I am presenting you: NSPatch

What does this do?
It extracts NSP containers using hactool, patches them to require the minimum needed FW version of the corresponding minimum needed Masterkey Revision required for crypto and then repacks the NSP container using a modified build of @rkk 's nspBuild.

WUT?
See this Thread by @Zocker4444 for reference.

So just Base Games?
Yep.

Download when?
Now. https://github.com/adrifcastr/NSPatch/releases/latest/

Update 2.0:

• fixed mkey detection
• fixed fw version bug in messagebox ( thanks @StarGazerTom )
• added update applyment feature
• Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience

Update 1.1:

• Fix crash for some users/enable patching all existing NSP's

Summary of the keyblobs
1.0.0 - 2.3.0
MasterKey Revision: 0 -> Patching would achieve a 2.X.X game be playable on 1.0.0

3.0.0
MasterKey Revision: 1 -> Patching would have no effect

3.0.1 - 3.0.2
MasterKey Revision: 2 -> Patching would achieve a 3.0.2 game be playable on 3.0.1

4.0.0 - 4.1.0
MasterKey Revision: 3 -> Patching would achieve a 4.1.0 game be playable on 4.0.0

5.0.0
MasterKey Revision: 4 -> Patching would achieve a 5.1.0 game be playable on 5.0.0

Pics?
Even better. GIF.

Does this just patch the xml

Do you think ut will work on 3.0.0?

If yes that change nothing for lower firmware user

 

[adrifcastr]

Do you think ut will work on 3.0.0?

I need to have a list of the master key revisions, their corresponding firmware versions and the games that require each key revision, then patching will work on any nsp.

It does if you are on a firmware that uses master key 4 crypto (4.x.x) as it'll allow to play any existing title until the next master key revision.

This is a huge stretch but how about 2.2.0?

For exemple mario tennis aces can be played on 3.0.0 ? Or keys is a problem ?

that won't work as 3.0.0 uses master key #3 and mario tennis aces requires at least #4 to be decrypted, see the metioned thread for a list.

And unpossible too add masterkey 4 on the 3.0.0 ?

I think you have the numbering for the keys wrong
1.0.0-2.3.0 use Master Key 0
3.0.0 uses Master Key 1
3.0.1-3.0.2 use Master Key 2
4.0.0-4.1.0 use Master Key 3
5.0.0-5.1.0 use Master Key 4

I think if it was, we wouldn't have any issues with patching and lower fw versions

 

[adrifcastr]

1.0.0-2.3.0 use Master Key 0
3.0.0 uses Master Key 1
3.0.1-3.0.2 use Master Key 2
4.0.0-4.1.0 use Master Key 3
5.0.0-5.1.0 use Master Key 4

Actually they were wrong at first, but I was pretty sure that I got the actual numbering after the other thread was fixed, I'll take some sleep and then get the numbering proofed, as for now NSPatch patches key 4 nsp's if the numbering went wrong, the displayed firmware within NSPatch is incorrect, but that does not affect the xml patch.

what I meant is in replies you made to other people you said that 3.0.0 uses key 3 and 4.x uses key 4

This is just speculative but wouldn't this be counterproductive? I think newer version of FW have things or files that some games may need and they could result in crash or something else, it's not just Stability Improvements.

Found the issue. Just add quotes and it works. Plus you have to manually create a tmp Folder in the app directory as shown by --pfs0dir=tmp

Neat, I just did what the thread in OP's link said and and put zeros in the required system version.

I had to put it in a location where the path had no spaces or it would close. The CMD command its running wont work if you have spaces
