They figured out how communication between wiiu and gamepad is working, so they know how the wiiu is streaming it's video to the gamepad.
This could lead to showing wiiu gamepad video on other devices like a pc screen.
This could also lead to using the wiiu gamepad as display device for something like a pc.
I have no idea how this would help piracy, so piracy isn't a valid reason to keep it a secret.
We will have to be patient a few more weeks to see what comes out of it.
You need a fast wifi n connection on the 5 Gig band to stream the video if I read correctly.
Before we all start disrespecting Team f0f, let's look at some facts.
Approx a year ago, they posted in their blog that they had an exploit and that the Wiiu was hacked. They also posted they had no interest in doing any further work with it.
It's very well possible that Ninty could fix the exploit security hole with a firmware update.
If they would release the exploit to the public, I am sure Ninty would examine it and see if they could fix it.
There is still a huge amount of work to do after an exploit is found. You will need to recreate a devkitpro and libogc environment.
This will take months of work, even for a high skilled experienced group of programmers (like Team f0f) Only after the creation of such a sdk, an average programmer can create some usefull homebrew programs for the console.
As they weren't interested to do that work, they left the door open for others that showed interest and gave us a way to keep the 3 ppc cores going in vwii mode.
They said they might consider releasing the exploit if someone proved they could do something usefull with that information, like running 3 core linux on the console.
Linux would make it possible to run homebrew and emulators without opening the gate to piracy as it uses a total different software framework than retail games do.
Porting existing emulators to linux is usually a not so difficult task if a port for generic pc linux already exists.
Maybe they created a linux, or maybe they even created a homebrew sdk based upon a microkernel (comparable to devkitpro and libogc, exept that those use pretty much the same microkernel as retail wii games do)
Whenever they feel like releasing something will depend upon it's maturity at the moment and will also depend upon the fact if ninty can easily fix the exploit.
They also stated that a 3 core linux for vwii mode and the one for wiiu mode would be pretty much the same.
So it's not like all efforts done to get it running on vwii mode are a waste of time.
With Sony and Microsoft releasing their new consoles, and Steam becoming a fact, we can only hope game developers will still show interest in the Wiiu.
The others players seem to have switched to Intel (Amd) based pc hardware.
Nintendo was able to interest a large non hard core gaming public with the wii, probably due to their inventive way of controlling their games.
The Wiiu has it's gamepad which you could call innovative, but the others players could create a similar gaming experience using a tablet as display device.
One thing is a fact, if piracy would become easy on the wiiu, it won't help for developers to show interest in creating wiiu games.
Let's hope a lot of people find a wiiu under the christmas tree so that sales of it get better compared to the competitors.
Maybe they should release a placebo exploit to keep everybody happy?
