Hacking Hykem's 5.5 iosu Exploit

[ArceusMI]

talking of linux, know what would be pretty fucking epic, steam OS on a wii U

Oh, I never thought of that... But wait. What kind of CPU does the WiiU even have? x86? x64? ARM? If it's ARM we could be SOL.

A PPC as a primary CPU that can interact with graphics and sound, and an ARM that does a lot of background tasks (that's what IOSU runs on). By the way, this is really easy information to look up.

Power PC. Possible...maybe

SteamOS is our Linux-based operating system. The base system draws from Debian 8

Yeah, in all honesty I just didn't feel like looking it up xD

So are you saying that the main processing gets done by the PPC then?

Yes, games only run code on the PPC, and the ARM can't even access graphics or sound.

The next issue once the OS is *ported* becomes actually having the games run. Most are developed for Windows, and maybe Mac/Linux if you're lucky. I'm not well versed in anything about PPC (other than the fact that old Macs used to have them), so I don't know if that would take another porting, but I'd believe so because x86-64 software doesn't run on ARM (RaspberryPi is a great example) so not too sure it would be very useful in the long run. Maybe, just maybe you could get the Steam Link system running.

as you wrote this I did think to myself, steam link might be more feasible, to get the pad running with it would be godlike.

EDIT:

• [/r/linux_gaming] Steam Link is "running a custom Linux kernel and a Valve-developed software stack" on ARMv7.

shit outa luck.

The pad most likely wouldn't be too hard, it's been softhacked already. It would be easier to just have maybe the Steam Link version of the OS to be ported. Let me do some research on how hard it would actually be...

Oof, the requirements are too killer...

• Intel or AMD 64-bit capable processor
• 4 GB (or more) RAM
• 200 GB or larger hard disk
• NVIDIA (post-Fermi graphics cards),[14] Intel, or AMD graphics card (Radeon HD 5XXX or newer)
• USB port for installation
• UEFI boot support

So the things that really get me are the HDD space, processor, and that last bit, UEFI. That requires some real modification to get rid of, IIRC.

thats steam OS, steam link is a custom linux kernel running on ARM7 mate, as a client it doesnt need to be powerful at all.

seems like a dead end, but you never know with these things

Good point. But the processor is still the issue. PPC is an outdated architecture now.

EDIT: Yeah. "Valve-developed software stack" kills it. Proprietary.

 

[loco365]

Can we run pyGecko and stuff with this IOSU exploit (or have the potential to do so?)

You shouldn't need IOSU to use pyGecko. You'd just need the ability to run code. Of course, once the 5.4.0 and 5.5.0 exploits are released, you should be able to.

since its a client, uses no power...moonlight project is pretty much steamlink for ARM, raspies etc,

@Marionumber1 the arm takes care of background tasks, if the system was fully exploited couldnt arm be utilised?

Don't forget that Moonlight is exclusively for host systems with an Nvidia GPU, though

Of course, but as I said, you couldn't use graphics or sound hardware from the ARM. You could always force the PPC to do that, but then why not just run everything on the PPC? Direct hardware access to the stuff IOSU usually handles is pretty difficult anyway.

As I mentioned, since PPC is an outdated arch, it's a bit harder to work with. Not much is made for it anymore, other than base systems and completely custom code. Having it be fully custom would require a lot more resources than most HB devs have. Hence why a big team like Nintendo or Debian can do it, but it would be harder for us.

 

[davetheshrew]

well at the very least we had one page of non shitposts, result!

That's because not ALL of this side of the forums is cancerous. We have some intelligent people. The kind of people Hykem would actually happily release an exploit for

To go back to the original post I made here, of course.

I get that, but the only way to use graphics and sound is to run PPC code.

Which in turn means it's gonna be harder to actually DO anything like what we were discussing. For example, Steam Link. You need at least enough power to send and decode the video stream from the host PC, so you'd ned the PPC code for that, which we would have to port from proprietary code.

Oh well, I'm going to sleep.
