Hacking Wii U Hacking & Homebrew Discussion

It still needs a lot of work to really have something usable.
For the moment I can't load all games, .

i was gonna say i never heard of 30 greatest games, had to google it.

It's a small game easy to load, that's why I choose this one

do you have the disk in the drive, or is it a digital download?

No disk in the drive, game is loaded by network from the computer.

Is the bottleneck in your setup the Wii U's wireless? I imagine networking via a USB network adapter is also slow. Would be nice to have onboard gigabit LAN like any self-respecting computer of the last decade has. :/

Can't Wait.....MMMMM

When an rpx tool decrytor is coming out?

There is a plugin for IDA that can disassemble wiiu rpx.

I use wifi yes. Not sure it's faster with the usb adaptator.

Question, can this lead to forcing a title to load arbitrary code outside of it's design ?

This is what is done here, (after other important steps) I launch the browser but instead of running the browser code, it runs the game code.

One more question: could this be an effective eShop spoofing method?

Yeah, totally!
Someone with IDA just needs to find out which functions, that the eshop RPX calls, lead to not being able to go into it and set this function call(s) to 0x00000000!

For the moment I can't load all games, but I see what's need to be done. And I still have network problems, it still crashes when loading some files.

invalid characters in the filenames?

Did you successfully load it completely and played it and all ? cause the video stops in the loading screen.
"Loadiing" <-- I have a feeling this will be a very famous name in the Wii U hacking scene. Great job !

might be worth trying a VC game, they are pretty light on the file system.....plus at least if we dont get eshop support its not the end of the road for testing out virtual console injections

oh and nes remix is only 140mb too

RPX loader almost working



Not fully functional, but it's a good start!
Also able to dump games rpx

Just wondering would this work better if you have an FTTP connection with ethernet cable on a 330/20MB which I have at home? I presume the faster your network at home the more efficient it will work. Great work by the way and news of course

Edit: I could test it out for you if you like, if you think it may help you.

Does it not work on how fast your local network is "PC to WiiU" and not your throughput to your house? so if you have a 1GB+ local network with an ethernet adapter on your wiiu, that would work OK with loading games to your wiiu.

Any chance you release your modded caffine that can dump the executables? it would be specialy helpfull to dum snes/nes executables to see if we can find the settings on the VC injects becuase the roms are inside the excutable itself so maybe the config stuff is too.

 

[ZoNtendo]

Secret...
If you need more fun:

great, you can do more hack like this ?

This remember me the first days of GameCube hacking. You were able to load entire games through network ^^

awesome

I'm pretty sure you need IOSU hack to spoof the firmware, but I didn't explore much the spoof topic =). But maybe ..

Did you successfully load it completely and played it and all ?

Nop I can't load the game complety, it always crashes at some point.
In the video it doesn't crash because I skipped the loading of one file with cafiine, so it can't loads till the end (when the file is retrieved by network, just after retrieving the data, the wiiu can't communicate anymore, I don't know why, maybe network problem, maybe thread problem, maybe i didn't implement well some filesystem function ...).
It also happens with other games I tried. Still investigating ...

Any chance you release your modded caffine that can dump the executables?

For the moment it's still in development state with most of the stuff done by hand. I'll try to make easy tools when everything will be released.
note : cafiine doesn't do the dump, it is only used to send the game files and mirroring the filesystem functions.

 

[Mega-Mew]

Yes! we all can its in the rpx, IDA can already dissemble the RPX all we need to do is find out how to get the floats from IDA
once we do that its all said and done. For every Wii u game about 95% of the speed offsets are in the floats

I'm sure he had to actually dump ram memory to get the speed though

It's not a RAM hack, it's do with cafiine.

 

[JaceCearK1]

Just found something interesting, does someone have interest in updating it a little bit?
