Hacking Wii U Hacking & Homebrew Discussion

Sounds very c64'ish
What song is it?

"Hot buttered " from Tempest & Reed.

We're beginning to discover the low-level USB interface, and documenting our progress here. As long as Nintendo hasn't done something weird, it should eventually allow for homebrew access to USB devices, like storage.

I didn't understand, does that mean that we will be able to use cafiine to load files from USB?

Yeah, that's one of the things it'll accomplish.

 

[motezazer]

Yeah, that's one of the things it'll accomplish.

Great! It is pretty annoying to load files from network.
Also I read you were on tracks for an IOSU exploit. That's great news!

Yes, definitively, 3DS has better security (and is almost 2 years older than Wii U!)
-hardware key scrambler
-bootrom PROPERLY disabled
-multiple encryption layers
-NX enforced even on the browser
-etc.

Also, the key region on the New 3DS is very strong (and I bet that every future Nintendo console will have a key region like New 3DS one)

Wouldn't it be easier at that point to use something other than cafiine? Or are different modes planned? (USB, Network, SD) I know a rewrite has been mentioned a few times. Just curious because network loading would be much better for debugging/testing. Copying files hundreds of times to make edits is a pita. Wii gave me enough headaches when VC injection was new. Lol

For SD the IOSU exploit needs to be achieved.

That wasn't the question.

 

[motezazer]

That wasn't the question.

But USB and network are planned.

The Cafiine rewrite would probably have multiple backends, including external storage (if we get that working in time) or the network.

3DS security is definitely better, but the Wii U browser enforces NX as well. The JIT area is a single exception to that, which still does W^X (either writable or executable, never both at once), and I believe the 3DS has that in its browser too.

Perhaps my informations are outdated.
In fail0verflow conference, they said a special exception for NX was enabled on browser, so ROP wasn't mandatory, we could get directly code execution. Maybe fixed with a firmware update.

fail0verflow didn't ever say that. I had that misconception way back in March last year, and comex explained to me what it really meant.

Could (TCP)Gecko dNet also maybe work via USB?

Didn't know that.
And I have to give a point to Wii U security : they made ODE difficult.

Assuming we get USB support (it's not a given at this point, but looks feasible), yes.

 

[IbbyPlays]

I am trying to think of a meet in the middle for Cafiine. A long time ago I though I heard of a usb cable with with a storage device in the middle that allowed you to have both computers read the hard drive at once.

 

[BullyWiiPlaza]

Why would you want that? Wireless is more convenient than cable except if you want slightly better performance.

 

[IbbyPlays]

The Cafiine rewrite would probably have multiple backends, including external storage (if we get that working in time) or the network.

If it did use external storage, would we still need the server and client setup?

 

[TotalInsanity4]

Fast question for one of the devs if they aren't busy: are you planning to develop a homebrew loader for the exploit to crash into, or are you just going to lay the groundwork for someone else?

 

[LawnMeower]

For the case that dumping the RAM over USB would be faster
