Hacking Coding vWii 3-core support - everything you need to know.

[Maxternal]

I don't see how they could leave a file on volatile memory.

Perhaps just by not zeroing it out or reusing those memory addresses when done executing it. The RAM stays powered when going into vWii mode so it's not necessarily cleared.

You kinda need WiiU mode to grab and decrypt that file - sorry!

Joostin enters sneaky mode.

Perhaps you could give us something like an exploit or whatever and we could work from there.

Oh, I have an awesome idea! We could exchange that for a Linux that uses all of the WiiU features that are available in vWii mode!

cafe2wii.elf is responsible to enter in Wii mode right, and it's on Wii U side?

 

[obcd]

That's right. It's either on the wiiu nand or on the wiiu emmc.
I get the feeling that the emmc contains the wiiu ppc stuff and the nand the arm stuff.
As sven mentionned nand, I'll put my money on the nand.
The wiiu part of that is encrypted with a different key than the vwii site. At least that's what I was hearing.

I wonder if Ninty was friendly enough to keep that key somewhere in memory?

Maybe boot0 -> boot1 -> boot2 still exists, but on the wiiu site of the nand instead of the vwii site.

I know this is a noob question but. What will vWii 3 core support do?

add support for three cores which means potentially better performance for multicore optimized applications.

people i have download the boot.dol and the elf file (1 is the minikernel from gclinux page), i start the dol but i see only black screen. I haven't download any distro iso or file, only the kernel...
how to insert options on xml file? give me a example of xml options please (with all the line)

sorry double post

First thing, you'll probably need BootMii IOS installed (I would assume you do, but some people that can install it as Boot2 didn't bother to also install it as IOS ... so just in case.) If you don't, you can either install if with the hackmii installer or you can install the WAD we have on our googlecode page (also linked with the downloads).

As far as adding options to the meta.xml file, the only options that would be relevant here would be bootmii=0 if you want it to try to run the ppcboot.elf file WITHOUT the BootMii IOS and the path= option if you didn't name the ELF file as "ppcboot.elf" and place it in the same folder as the DOL file you ran. You would add it to the XML like this

<arguments>
  <arg>bootmii=0</arg>
  <arg>path=/folder/filename.elf</arg>
</arguments>

If you don't want one of those arguments or the other, just remove that line. (I don't remember how old the boot.dol in that download is. There used to be a bug that setting bootmii=0 would make USB not work at all for you once in Linux)

A few more important notes :
1. The ELF file HAS to be on SD since Mini can't load anything off of USB.
2. Mini can't deal with long filenames either so make sure that the folder the ELF file is in doesn't have any part of it more than 8 characters long (not including the optional "." and the maximum of 3 character extension)
3. If you're running the boot.dol off anything other than SD (e.g. USB/SD gecko/wiiload) and don't have the path= option set in the meta.xml, it will look for the ELF file in sd:/bootmii/ppcboot.elf

If you're looking for kernel options, that can't be set in the XML. Those are hard coded into the ELF file and meant to be changed with a hex editor (by searching for something like for_additional_kernel_options_targetted_at_hexedit_lovers). Those, I believe, are set to look for a second partition on your SD card. If you're using the mikep5 kernel off the gclinux page like you said, though, it shouldn't black screen on you IIRC, even if it can't find that partition. It should just show a message about not being able to find a filesystem and then reboot after exactly 3 minutes. A black screen hopefully indicates one of the above problems with it not finding the ELF file or the bootmii IOS. If you're using the ppcboot.elf file packaged with the boot.dol file, though, the black screen is normal when it either can't find that partition or you have set bootmii=0 BUT it should still reset automatically after 3 minutes.

If you keep having problems, let me know.

Hey Maxternal, what machine do you have is the closest to a Wii U because until you can afford one you're gonna have to work with whatcha got.

A normal Wii

Well...Hey since nobody is listening to me about the "Donation for Maxternal's Wii U first" idea anyway that just gave me an idea! We can use a computer like a desktop, laptop heck you can even use tablet in combination with the latter two with an an operating system or two that's the closest to the Wii U's hardware and operating system. We can then experiment our findings by using those things.

Some examples :

A Tri-Core PowerPC processor

A slot for running AMD Radeon cards or just built in AMD Radeon

2GB+ of RAM

An operating system with a virtual PC running inside it

 

[bravest]

Can anyone test the following? I made some slight modifications to the payload.
Ideally it should boot into linux. Rename vmlinux to ppcboot.elf and put it in the usual place.

I think you'll struggle finding any 3-core PPC processors other than the Wii-U! The Xbox 360 might come close, but it uses a significantly newer Xenon architecture which (from my understanding) doesn't hold a huge resemblance to the PPC 750 architecture used in the Mac G3's and Wii-U.

 

[Pogostick]

I said a desktop or a laptop. Also what I meant by "tablet in combination with the latter two" was a non-Nintendo tablet combined with a laptop or desktop.

Further more the 3-Core processor in a desktop/laptop/tablet is an EXAMPLE. I'm not talking about video game consoles.

So you essentially want somebody to build something that is WiiU like for the purposes of testing hacks for Maxternal. Okay.
Such a theoretical thing would be useless because its not exactly the same as WiiU and is not running its firmware. This is not like medical science where you can test human diseases on mice because both organisms are mammals.

Stick to the fundraising drive idea and don't get discouraged if people aren't responding to you. The best thing you can do is not become another Ray Lewis by creating a side show.

 

[obcd]

And slowly our ship is diverting again from coding vWii 3-core support.

Couldn't some developper with knowledge of Forum design create a sandbox into which we could catch all the Trolls?
Only it should be a sandbox with quicksand, making them dissapear as well.
Maybe I can even convince Marcan to give the exploit to whoever succeeds in this task.

Well, you don't have to build a desktop/laptop/tablet. You can just buy a desktop/laptop/tablet. That's what I meant since it's the holidays. Again can't we just try get close to the Wii U firmware. Does have to be exactly the same as the Wii U?

 

[Kargaroc]

Of course, since it's the holidays, you could also just buy him a Wii U and not have to compromise on anything. Tempted to pay for it myself, but I don't have too much money to spend

Then just donate a few dollars like me and a bunch of others have! If everyone chips in a little bit then Maxternall will have a Wii-U in no time.
