Gave it a shot, and all seemed to work well, but its still making 0kb Patched.NSP's?

Working fine on my side.
Do you have a proper installation of python 3.5 including path variables?

Also to anyone else: I'm looking for someone who is able to translate from python to c# as I'd like to reimpl nspbuild and get rid of python being a dependency

(Also the next release will probably have hactool and it's dlls packed in)

Thanks even for that release... I've tried with my Switch... I'm on 4.0.1... the procedure is completed and patched.nsp created but seems I received always the same message to update my Switch... I'm trying to start a 4.1 games on my 4.0.1...

Anyway thanks for your effort!

I don't think 4.0.1 really offers anything special if you wanna just update to 4.1.

@adrifcastr I've created a c++ patcher (no need to unpack and repack). You can either compile it and distribute it together with your app or port the code to your favorite language.
Further optimizations would be to do a reverse search (as the XMLs appear to be packed towards the end) but it's fast enough form me as it is. Furthermore, it's open-source so people can grab it and improve it if they want.

Ah, its likely I'm missing python, I just recently did a reinstall of Win10, so that's fully possible where the issue lays.

oh wow, c++ and c# are even more different than I originally thought. I can read 50% of what is what, but that looks really good to me, great job, thanks a lot!

Here's a list of what I believe the "proper" lowest RequiredSystemVersion values should be for each KeyGeneration, from what I can gather from the Switchbrew wiki, if anyone wants to incorporate this rather than always setting to 0:

# Lowest RequiredSystemVersion values for each KeyGeneration
KG_LOWEST_RSV = {
    0: 0,  # Keyblob 0
    1: 450,  # Keyblob 1, System Version 1.0.0
    2: 201327002,  # Keyblob 2, System Version 3.0.0
    3: 201392178,  # Keyblob 3, System Version 3.0.1
    4: 268435656,  # Keyblob 4, System Version 4.0.0
    5: 335544750,  # Keyblob 5, System Version 5.0.0
}

thanks, that's what probably also causes most of the issues, I was looking to also get that implemented!

Part of it is C for better efficiency.

Regarding the keyblobs, I already encountered different values. Maybe for interim versions. Sonic Mania Plus is 201326592 and is supposedly 5.x.x

I've seen interim values that aren't these known ones too. Check the Title_list article on the switchbrew wiki, under System Data Archives / SystemVersion. Those seem to be the values for the actual FW updates. I'm assuming values outside of those were development fw versions that didn't get pushed as prod fw versions.

Except for Updates, those often have some wild RequiredSystemVersions, no idea why.

I just want to stick there in order to preserve efuse...

4.0.0 and 4.1.0 both have 5 burned fuses. you can change between them at your will.

the new update is amazong, but it strange, i patched shaq fu my self and worked on 4.1
but now with the new version it patched it to work on 5.0.0, very weird.

Yeah seems that that somehow happens to some people, probably because of my "raw" way to patch, I'll edit, compile and embed @rrocha 's code as a workaround until I manage to reimplement it in c#

Thanks... I didn't know about that... So basically I need to find now a cartridge with 4.1 inside...

Labo toycon kit or just use rajkosto's update method

Or better yet, look for the xml in the header, and directly jump to its offset in the filedata.
