Hacking H3 Files?

DanTheMan827 · Oct 30, 2016

Is there any better way to detect if an app file has a corresponding h3 file on NUS rather than checking the server if they exist?

I saw something about if the content type in the TMD is 0x2003 that it has one but that doesn't appear to always be the case...

what do you mean not always the case?
did you find a app with a h3 which doesn't have the type set to 0x2003 ?

do you have an easy way to check each type? an extractor, or content lister?
I made a template for HexWorkshop, if you want.
when you add the template to your tmd, be sure to select the "wiiu" tmd, and lock it to 0x00 (start of the file)

from the screenshot in the linked thread, you can see the 3 last contents (0x1c, 04 and 05) should have a .h3

since nintendo could change what content types need h3 files with an update, for example add a new content type with a new game, vc game, etc... (possibly, although i doubt they would do that)
i think it is safest to just try and download for each content, it's not really ugly, it's so simple so, why not

but i agree it would be nice to be 100% certain, but i don't want to spend the time testing until i am confident, and even so, my above sentence could end up true.

According to crediar it's a bit flag of 0x2 on the content type

So the code would be something like this

Code:

((cType & 0x2) > 0)

The Minecraft update is an example that 0x2003 isn't the only type with a h3 file

It seems to be that bit flag, I haven't found any counter-examples yet.
I figured out how the .h3 hashes work in nuspy, see the source for details.

yeah that is what jnus does, i'm not sure about nusgrabber, i guess so, that jnus takes from that.
but i'll keep it ugly for now

confuse the anthropologists in 400 years time.

Hey @DanTheMan827 - in next day-two I'll test bunch of titles (both base game and updates). Whatever happens I'll provide you with test report - if anything failed using your awesome uTikDownloadhelper.
