Video: Wii U Teaser: The Homebrew Channel on Wii U by Fail0verflow

Sponsored Links
107w ago - Following up on the previous Nintendo Wii U hacking news, today console hacker and mod-chip developer [Register or Login to view links] of fail0verflow has shared a Wii U teaser video via 0xf0f on YouTube demonstrating The Homebrew Channel below.

To quote: "We finally have a YouTube channel and we thought we’d kick things off with a little teaser:

Keep in mind that this is purely a demonstration at this stage. Depending on how things progress and what direction development takes, we may or may not release something like this in this form. Please don't ask for release dates. We'd rather spend time investigating the new system than putting together a release that may or may not end up being the Right Way to do things in the future.

Please ignore the blue blinks. The monitor kind of sucks at syncing to component video sometimes. I would’ve used HDMI, but the Wii U cannot output analog audio simultaneously with HDMI (at least not for the Wii U menu part), and I cannot capture HDMI audio."

On the Wii U specs, Marcan Tweeted the following: We're calling the Wii U security processor the Starbuck (vs. Starlet on Wii). And it seems to be about equally vulnerable, too.

Sorry, I'd rather not talk about how I got that yet. It doesn’t involve leaks, it involves Wii U hacks

He also stated the Wii U offers a 1.24 GHz CPU with 3 PowerPC 750 type cores with the GPU clocked at GPU core at 549MHz. The Wii U does have a higher IPC meaning the processor can do more work per clock cycle so it can't be directly compared to PS3 and XBox 360.

From the video's caption: "A quick demonstration of The Homebrew Channel installing and working on a Wii U.

There is no set release date, please don't ask. This is just a demonstration. Please ignore the blue blinks. The monitor kind of sucks at syncing to component video sometimes, and I cannot capture audio from HDMI."

Hopefully this delay won't turn into another money-making venture led by Max Louarn and Paul Owen profiting off the scene as was done with the PlayStation 3 and PS3 DRM-infected dongles.

Also below is a video (via gbatemp.net/threads/devolution.338544/) of a GameCube game running on Wii U via Devolution by Tueidj. To quote: DevolUtion? Yo dawg, we put backwards compatibility in your backwards compatibility so you could run gamecube games over HDMI.

Unfortunately he shows no proof of it actually being used on the Wii U. Also in the video below he couldn't get past the "Press Start" screen.

How to use Devolution with backup discs

Devolution is a Gamecube loader for the Wii that allows both SD and USB loading with excellent compatibility along with audio streaming support. Many people are interested in using Devolution to play their favorite Gamecube games on their Wiis but have been frustrated by the program's inclusion of severe anti-piracy measures. While some claim to have cracked Devolution's code, a version without AP has not been publicly released. As compatibility improves, Nintendont promises to be a worthy AP-free alternative in the future. For now this leaves hardware, in the form of a modchip, as the best way forward with Devolution.

The following has been thoroughly tested and is known to be working. Other modchips may also work (many are known to be incompatible with the program's AP even when using retail discs). Please update this thread if you find another working modchip or firmware.

What's required:

  • Wii with an early drive (DMS, D2A, D2B) that can read burned DVDs
  • Wiikey v1 modchip or DIY equivalent
  • Wiikey 1.9b firmware and matching config disc (NOT 1.99BETA)
  • Devolution r128 (or earlier)
  • Devolution r197
  • Burned backup of Gamecube game

The files needed are available on the internet with a little bit of searching.

This will NOT work with:

  • Wii U
  • Wiis with D2C or newer drives
  • Devolution r200, because it uses a different verification scheme

How to verify backups:

To be able to verify burned discs with Devolution, the Wiikey must first be flashed with the older 1.9b firmware and have the region override feature turned OFF using the Wiikey config disc. Once this has been done, simply insert the backup when required for verification and Devolution r128 (or earlier) will verify the backup just like a retail disc. Repeat the process with backups of the rest of your favorite Gamecube games. This method works with either the standalone version of Devolution or by using the loader.bin with a USB loader. After all backup discs have been successfully verified, replace version r128 with r197 for the best game compatibility.

Have fun playing Gamecube games with Devolution!

In related Wii U news today Crediar shared a video demonstrating running Homebrew Launcher on the Wii U in Wii Mode below with a screen capture of the Wii Mode OTP keys for those interested.

Here is some updated news on the Nintendo Wii-U hacking from Wii-U scene profiteers Max Louarn and GaryOPA (aka Gary Wayne Bowser) alongside marcan42, as follows:

Coming Soon to a Wii-U Near U

What is it? Wait and see

Four Horseman Set Sights On Wii-U

Yep, it is finally upon us, but lucky for us humans the Apocalypse is happening to just Nintendo

A year in making, the rumors claim, but end is in sight for the Nintendo Wii U, as the Four Horsemen have been enlisted to bring the second coming to Nintendo in the form of Homebrew finally for Wii U.

BannerBomb Version 2, the Second Coming is happening for Nintendo on its latest flagship next-gen console the Wii U, roughly a year after its launch, it seems four unknown well at least this time around they are hiding their online nicks from the big 'N' band of happy pitchfork lawyers, and coming together as the Four Horsemen, along with secret hand-picked group of five beta testers, one of whom seem to have loose lips and sent off some 'anon' emails with teasers to a 'scene site' as such the Four Horsemen have quickly gather up their gear, and rumored to be sending their fury off to video camera to prove the the world the second coming is happening to Nintendo and it might be as early as this Wednesday we see a release to make sure the big 'N' does not patch this 128x128 graphical overflow exploit that been uncovered which the rumor claims of 'Hello World' has already been done.

So stay tuned to this channel as time is ticking fast, and this U Bomb by the Four Horsemen is just around the corner.

Update: Below is another picture attached and videos, as follows:

Four Horsemen Deliver The Video

Showed a Wiiu Brew icon on both the main display and the gamepad, they pressed the icon on the game pad then a WiiU Brew Screen (similar to the Wii screen when you launch the Wii) then the video faded out.

So the did manage to install something on the Wii U and launch it. What it actually does, no one knows but it does lend some credence to their claims that they've hacked the Wii U.

(Proof of Concept) GameCube games in vWii on Wii U

First of all no this isn't DIOS MIOS because that would never work.

This is written pretty much from scratch and there are still many issues especially with the sound that's why I overlayed a nice music track.

There is obviously no way to use a GC controller on a Wii U and getting wiimotes/CC to work is way too complicated, so what I am using here is a PS3 controller connected via USB.

The Mega Man 10 channel is just my lazy way of loading sneek, don't need any fancy banners

Wii U Dev Console Photos

From assbasket (via gbatemp.net/threads/wii-u-developer-console-wont-boot-retail-disc-pics-help.358882/): I bought a used wii u from an online ad in San Francisco just a few days ago. Met up in a public place with an outlet so I knew it worked before I paid.

I was told I'd need to connect to the internet and update it before it would play games.

I might have screwed up before I got that far, but it's a rare piece of gear and I'm not really worried. Minorly frustrated maybe.

Pictures are included below. It has a green face plate like the wii dev unit did. The controller has a boxy bit sticking out of the middle top edge.

I tried booting NSMBWu and it won't recognize the disc.

I clicked something called DEVMENU but it wouldn't let me get back out of it.

That was when I had a 1080p HDTV to test it on.

Now I'm at home with only a 720p and it doesn't seem to give a signal to that tv.

Looking for help online. Internet hasn't been much help.

I've hammered search engines and searched this forum and lots of others looking for help, reference, images, anything. There doesn't seem to be any available public information about this. At least not yet anyway.

I spoke with a guy who said he'd helped test a sega title for wiiu, he said the menu looks very old. TVii? He may be right.

I'll keep messing with it whenever I can get my hands on a 1080p monitor, tv, screen, whatever. But my current tv isn't showing me the DEVMENU screen in the pic below, so I'm stuck for tonight.

This dump weighs in at a hefty 23.256GB, and what’s extra interesting is the AES key that is included in the read me.

From Fail0verFlow's blog (via fail0verflow.com/blog/2013/espresso.html) to quote:

The future of console homebrew (and a shot of Espresso) by marcan

It’s been almost 7 years since the Wii was released. Back in 2006, not many owned a living room PC. PCs were still relatively bulky, and the Chinese offerings were limited to horrible media players. At the time, the prospect of having a game console double as a HTPC and being able to browse the web, play games for older platforms with emulation, and run homebrew games on a device which you already had in the living room was rather appealing.

Fast forward to today. Mobile SoCs have made huge advances - you can get a quad-core chip in a phone these days - and have made the jump to the living room. Spend $25 and you can get a Raspberry Pi, which is about on par with the Wii at 1/10 of the launch price and 1/7th of the power consumption (with HD video). Spend $100 and you can get an Ouya, which beats the Wii U’s CPU and doesn’t have too shabby graphics at one third the cost.

These mobile-derived devices aren’t quite a replacement for game consoles yet, but they’re catching up fast. They’re cheap enough that they’re almost disposable. The software ecosystem is much larger and wider than any console has ever had. More importantly, they’re open, and the development tools and environments are way better for open development than any game console ever was.

The Wii U isn’t a particularly interesting device. It has the same old Wii CPU, times three. The GPU is a standard, and somewhat outdated Radeon core. The peripheral hardware is standard - SD, USB, SATA, WiFi, etc. The Wii hardware has been either kept as-is or replaced with compatibility shims. The only interesting bit is the controller, but there is already significant work underway to be able to use it with a PC (all you need is a wireless card capable of 5GHz 802.11n AP mode and special software). Even on the Wii U itself, the gamepad is managed by an independent Broadcom SoC that has its own firmware and communicates with the rest of the system via bog-standard USB and one of the video output heads on the Radeon.

The same goes, by the way, for the Xbox Durango and the Playstation Orbis. They’re both glorified PCs. With Valve’s Steam Box coming up, there will be little advantage to either of the first consoles other than potentially new input devices and exclusive games. And the Steam Box will almost certainly be hackable with trivial to no effort.

So where does that leave us? When the Wii U came out, our hacker instincts kicked in and we started looking into ways of breaking into the hardware. A few days before launch we had a firmware update scraper going. Over the next 30 days, we reached most of the milestones required to be able to say that we hacked the device; without going into details, there is basically no security left to break into, other than a mostly unimportant step of the boot process.

What would remain is the tedious work of developing the open frameworks required to bootstrap a homebrew community, documenting everything, reverse engineering all of the new hardware, developing a persistent exploit (think tethered vs. untethered iPhone jailbreak, except without any extra hardware or cables), and packaging it all up.

Over the next few months, interest faded. I took a break to work on other projects. There wasn’t much of a reaction from the Wii homebrew community. Is it really worth going through all that effort when we already have open devices that are affordable and widely available? About 31 trustworthy people, most of them well-known people in the homebrew community, have access to what we developed, yet nobody stepped up to start working on a homebrew platform for the Wii U.

At the same time, there is an eternal clash between the homebrew community and those interested in pirating games. Writing homebrew software and frameworks is rather difficult - it requires new code to be written to support the hardware, which must be reverse engineered first. Convincing a game console to load copied games is comparatively simpler, as only the bare minimum amount of code patches required to convince the game/OS to load the game from alternate storage media are required.

For example, on the PS3, the kernel payload of the first game loaders was a tiny system call patch, and I wrote an (unreleased) Wii USB loader using existing homebrew frameworks in a couple hundred lines of code, as a proof of concept. Every console after the PS2 was initially broken to run open homebrew code, and only later did piracy show up (excluding disc-drive-based hacks, which I consider a different category).

I think we may have reached the point where homebrew on closed game consoles is no longer appealing. The effort required to develop and maintain an environment for a big, complex modern game console is huge. The cat and mouse game with the manufacturer requires ongoing effort. There is a very real threat of litigation. Game pirates would become not just big users of the result of those efforts, but by far the overwhelming majority (not because there are more pirates, but because there are fewer homebrewers). The fact that the Wii U isn’t selling nearly as well as the Wii did doesn’t help drive enthusiasm either.

I could be wrong, of course. Maybe it’s just that I have a full-time job now and less of a chance to spend all-nighters staring at assembly code. Maybe there are tons of prospective Wii U homebrew developers quietly waiting in the sidelines for a release. Maybe we’ve just gotten lazy.

We could just release everything as-is, of course. However, we tried that with the PS3, and the results were not only disappointing, but we actually ended up in an undeserved legal mess. Homebrew for the PS3 is basically nonexistent, and all anyone cares about is piracy. This is not a situation which we want to see happen again.

So, instead, we can go for a compromise. Our original idea for Wii U homebrew was to “escape” from the Wii mode sandbox and enable the new Wii U hardware. This appeared possible initially, but unfortunately, it turned out that a few critical hardware registers were irreversibly disabled in Wii mode. However, due to the design of the Wii U’s architecture, a few things can be re-enabled. One of those is the multicore support of the Espresso CPU.

On the Wii, the Broadway CPU had no built-in security: games ran on the bare metal and the Starlet handled all security. The Starlet was responsible for kickstarting the Broadway and feeding it code to run. The Wii U extends this architecture by putting some extra security inside the Espresso CPU: now, the Espresso has its own secure boot ROM, like the Starbuck, and will only boot a signed and encrypted code package. This package (which we call an ancast image) is delivered by the Starbuck and verified and decrypted when the Espresso is reset.

This happens in Wii mode too. However, Wii mode software knows nothing of this mechanism. Nintendo worked around this by transparently replacing the NANDloader (which is usually the first code that runs on the Broadway when it boots) with a modified version, encrypted and signed using the new format. The Starbuck (running vWii IOS) loads the new NANDLoader to RAM as it normally would, but when the Espresso is reset, it instead runs its boot ROM.

The ROM decrypts the NANDLoader in-place and verifies it against its hardcoded ECDSA public key. If the verification succeeds, it jumps to its entrypoint. The very first thing that the NANDLoader does is turn off the Espresso features and put it into Wii compatibility mode. The new NANDLoader is stored in dedicated vWii mode titles 1-200 and 1-201 (there are two variants, but 1-200 is equivalent to the “normal” NANDLoader).

Incidentally, for vWii mode, we made a minor tweak to HBC so that its binary can both be loaded standalone as was the case on the Wii, and also works together with a NANDloader - this means we can use the same binary for both platforms, and we don’t have to ship a separate NANDloader that would be replaced in vWii mode.

Thankfully, even though the Espresso has ROM security now, unlike the Starlet/Starbuck, it has no memory firewall or similar protection (i.e. AHBPROT). This means that we are free to mess with the contents of memory while the Espresso boots. We can perform a completely trivial and reliable race attack and gain control before the NANDloader has a chance to disable anything. Here’s how. You will have to be able to run code on the Starlet: you can either use Mini or hotpatch IOS using the AHBPROT feature of HBC.

Load the NANDloader to RAM (it is a standard DOL binary and should be loaded as indicated in its header). Note that you’ll have to gain access to 1-200 or 1-201 for this. Don’t bundle it in your app; that would not be redistributable and wrong. Instead, read it from NAND directly (mini), or patch IOS to let you access it, or use the existing title boot functionality in IOS (that already loads the NANDloader from 1-200) and just patch the part where the PPC is reset (see below).

Perform the standard PowerPC reset sequence (this is Mini code, see hollywood.h for the constants):

Note that it is not necessary to load any EXI bootstrap code, as the Espresso always boots from ROM.

Immediately start watching memory location 0x1330100 (0x81330100). Make sure to either use an uncached mapping or invalidate the cache every time. You may need to perform an ahb_flush_from(AHB_1) every time to make sure the AHB buffers don’t bite you. Look for a change in the data at that address: it is the first instruction of the NANDloader, and the ROM will start decrypting there. Verification happens simultaneously with decryption.

Replace the (now decrypted) instruction at that address with a jump to your own PowerPC code. Make sure to flush if not using an uncached mapping. The timing is pretty lenient here; the ROM is busy decrypting and verifying the rest of the NANDloader at this point, so you have plenty of time to detect and swap the instruction before the ROM jumps to it.

To be able to use the extra cores, you will have to initialize them. There are also a number of settings related to the bus and memory coherency. Some of these may not be applicable to Wii mode, so you will have to experiment. These are the important steps (in pseudo-C), reverse engineered from the early initialization code of the Cafe OS (Wii U mode) kernel (this runs initially for core0, and then every other core also runs this code as it is bootstrapped):

[Register or Login to view code]

Note that cores 1 and 2 will start at the system reset vector, which should jump to code equivalent to the above. It is currently unclear what controls whether the cores end up with MSR[IP]=1 (high vectors) or MSR[IP]=0 (low vectors), but I’m pretty sure that at least in Wii mode you end up booting with IP=0 by default (vector 0x100 in MEM1), although one of the above settings might change that. Experiment. Just flipping the two boot bits in SCR is enough to get the two other cores up without doing anything else, although coherency will probably be broken/disabled. Also, keep in mind that this trick gets you access to all 3 cores but they still run at the old Wii speed (729MHz). Speeding up the Espresso probably requires full access to Wii U mode.

The important SPRs are these:

So what can you do with this? Well, libogc is probably near impossible to turn into an SMP-capable scheduler (and there are so many other problems with it that trying to keep using it for Wii U mode would be a terrible plan). However, it should be possible to port Linux to have tri-core support on the Wii U. It might also be possible to use the two extra cores in libogc apps purely for number crunching, with carefully designed locking (outside of libogc) and without calling any libogc functions from the other two cores (or any non-reentrant libc functions).

Personally, I’d like to see a Linux port taking advantage of this (using Linux was my initial goal in Wii U mode, though I never got around to starting the port). Linux is the ideal choice for Wii U mode, as it has native drivers for most of the remaining hardware, and most importantly, it should be a lot easier to port the existing open source Radeon drivers to work on the Latte than to write one from scratch. The Wii U has tons of RAM, unlike the Wii, and natively runs a multitasking OS with paging and memory protection anyway, so there’s little advantage to not just using Linux.

Getting multicore support into some kind of homebrew platform is one of the many steps required to get to a Wii U homebrew ecosystem, so consider this a test to gauge the interest of the homebrew community. If there ends up being significant interest and progress is made, we will reconsider working towards a Wii U-mode homebrew ecosystem (or perhaps just pass on what we have to those who are more motivated than we are).

One final note: on the Espresso, the exclusive load and store instructions (lwarx and stwcx) are subtly broken and need a workaround. If you are seriously interested in this, and you have started working on it, ping me on IRC and I’ll let you know about the specific workaround that is required (I’m just too lazy to write it all out right now) and also gladly answer any other questions.

Finally, from IRC:

Update: To clarify, this only yields access to the extra cores, not the extra RAM and the rest of the hardware. For that, you’ll need a Wii U mode exploit. We do have such an exploit, but right now I believe that, if it were released, there wouldn’t be enough developer interest to kickstart a healthy homebrew ecosystem; if e.g. a Linux port to vWii-mode Espresso is developed, I will gladly stand corrected (and such a Linux port would be directly applicable to Wii U mode, modulo a few minor memory mapping differences, so it’s not wasted effort).

I think it's apparent that he is trying to drum up interest or see who, if anybody, is interested in this work. So far it seems as if only end users are showing interest.

Below is a guide on how to get Nintendo Wii game backups working on the Wii U (via wiiuhax.com/wiiuhax-com-tutorial-how-to-get-wii-backups-working-on-the-wii-u-step-by-step-noob-friendly/) , as follows:

How to Get Nintendo Wii Backups Working on the Wii U Guide

CAUTION! Read these instructions carefully, at least twice before proceeding. Never mix and match Wii and Wii U WAD files. The two are separate things. Failure to follow instructions or warnings may result in brick. Following this tutorial may result in voiding your system warranty. This Web site and its authors are NOT resposible for any damage or loss that may occur by following this tutorial.

Step #1: Follow the .Wad Manager Tutorial if you haven't already done so. (If you've run it before and are having problems getting backups working after this tutorial, follow that tutorial again and start this one from the beginning.)

Step #2 (optional): Backup your Wii Mode NAND.

Step #3: Download D2X cIOS Installer 2.2 (d2x-cios-installer.googlecode.com/files/d2x%20cIOS%20Installer%20v2.2.rar) and d2x-v10-beta53-alt-vWii.zip (d2x-cios.googlecode.com/files/d2x-v10-beta53-alt-vWii.zip) You should have a folder 'd2x-v10-beta53-alt-vWii' in the d2x cios installer v2.2 folder. So it should look something like this: /apps/d2x cIOS Installer 2.2/d2x-v10-beta53-alt-vWii. Also download the latest version of WiiFlow (code.google.com/p/wiiflow/downloads/list).

Step #4: Extract the D2x cIOS 2.2 installer first. Move to the APPS folder on your SD card. Then extract and move the d2x-v10-beta53-alt.vWii.zip files to the D2X Installer folder in your \apps\ Extract the latest version of WiiFlow to your \apps\ folder too

Step #5: You need the following THREE files in the root of your SD card:

  • IOS56-64-v5918.wad
  • IOS57-64-v6175.wad
  • IOS58-64-v6432.wad

How to get them:

  • Download Bluedump 0.3 (bluedump.googlecode.com/svn/trunk/HBC/BlueDump%20Alpha%203/boot.dol) and extract the files to folder titled Bluedump 0.4a
  • Rename bluedump-alpha04.dol to boot.dol and place it in a folder titled Bluedump 0.4a in your /apps/ folder of your SD card (You should have /apps/Bluedump 0.4a/boot.dol)
  • Launch BlueDump via HBC. With the arrow on "00000001 - SYSTEM TITLES" Press the A Button. Using the D-PAD press DOWN until you are on the desired system title and then press the '1? Button on your Wii Mote. Using the D-PAD change the bracket selection to "Save as WAD" and press the A button, press A Button again for "Save to SD".
  • Go to the \BlueDump\WAD\ folder on your SD. Rename the 56, 57, 58 WADs according to the filenames: IOS56-64-v5918.wad, IOS57-64-v6175.wad, and IOS58-64-v6432.wad Move them to the ROOT of your SD card.

Step #6: Boot into Wii Mode, launch HBC, and from there launch d2x cios installer. Press A to get past the intro screen, and press A again when prompted about selecting IOS 236.

Step #7: You should now be at the INSTALLATION PROCESS screen. There should be an arrow under SETTINGS on "Select Cios".

  • Using the D-PAD press RIGHT until you can see "d2x-v10-beta53-alt.vWii" in the "Select cIOS" brackets. Once that is selected, press DOWN on the DPAD, moving the arrow to "Select cIOS base". Press RIGHT until "56? is in the brackets. (leave "Select cIOS slot" at "249?) With "d2x-v10-beta53-alt.vWii" under "Select cIOS" and "Select cIOS base" on "56? Press A.
  • Once it installs press A to continue. Now change the "Select cIOS base" to "57? and Press A, then Press A again to continue.
  • Now finally change the "Select cIOS" base to "58? and Press A then press B to quit once the installation successfully completes.

Step #8: Return to HBC, plug in your USB device to the Wii U's back upper-most USB port, launch WiiFlow and enjoy playing Wii Backups on your Wii U!

That's it! You should now be able to launch WiiFlow and load Wii Backups. (NOTE: as of the time of this writing USBLoader GX does not appear to work, future updates should fix this)

A special thanks to bubba for his contributions to this tutorial.
