Hacking Wii U Hacking & Homebrew Discussion

Actually not even an IOSU exploit would allow that, you'd have to defeat the loader because now it checks if the program is legit both at install time and every time you open it, so even if you were somehow able to install it you couldn't make it boot.

Ah, right. Is the loader part of IOSU?

No, the loader is PowerPC code with higher privileges, though still limited to userspace. Since it handles RPX/RPL loading, it has the ability to make memory writable and executable. NWP is somewhat mistaken about its role. IOSU's security code verifies titles that it launches, and Cafe OS invokes the loader to actually put the executable and its libraries in memory.

Basically like the 3DS then. Gateway got a userland browser exploit which then triggers a kernel exploit to let them boot into a custom firmware. Installed apps are non-persistent and won't boot in the "normal" system menu.

So basically the same should be doable for the Wii U, shouldn't it?

Theoretically, yes, you could port Linux or MN1's DarkSide OS, or a custom firmware and boot into it.

That sounds like quite a lot of possibilities. You devs have really achieved a lot and i know a lot of people are grateful for your work on this.

I just wonder why there seems to be so little interest from most people who matter (other devs) on developing a homebrew 'framework' for the wii U?

I'm sure the interest will be there once kernel stuff is public and development on a framework can actually start.

For future reference, does a use-after-free bug with a working LayoutTest mean you've found an exploitable bug?

Not necessarily, it needs to be evaluated case-by-case.

I looked at another thread (can't remember where, it was a few days ago) where someone is reverse engineering Gatway's code & looking into how they get the launcher.dat to boot through the new webkit exploit. Would it even be possible to go down the emunand route with the wii u?

Can someone make an windows build of this program?

It depends on how various modules interact with the system nand, but I wouldn't say it's impossible.

So my question from a long time ago still stands. If games and most software run in userspace, can we store our programs on the system as browser save-data.

Has there been any progress evaluating my bug? I know there isn't a definitive conclusion (you would have told me), but have you looked into it yet?

I'm looking into a different bug right now, and trying to evaluate it.

 

[OncleJulien]

i'll let a mod know the pm system is down.

This.
and it's not "your" bug.

I know this is a super non-sequitur, but I need an answer: Does DiscU work on Windows 7 x64? Because on my system, it seems to be missing some dependencies that are Windows 8-only (though this could be an error).

I see no reason why it shouldn't work, I don't have Windows 7 to test though. What specifically does it say?
EDIT: Also, can we continue this dicussion over here?

He's using it as a form of reference, it's not him attempting to gloat or anything.
It's shorter than writing "on that bug which was posted earlier by me?" since he has only posted one 'bug'. It's simpler for everybody if he labels it as such.
No confusing references in between, just solid information.

Please let us just not argue semantics, and keep the discussion civil.

 

[IbbyPlays]

Just making sure, the release of the kernel exploit will be announced in this thread right?
