New features include USB keyboard support in the Mii channel, enhanced parental controls, and that's where the fun stops: the update also apparently deletes the Homebrew Channel and any other unofficial channels and promises to "check for and automatically remove" modified save files from your system—which is the method used to execute the famous Twilight Hack that makes all the homebrew possible. Not sure whether that means it will disable such save files going forward—hopefully not.

So at the moment, if you have homebrew on your Wii or are planning to (using our handy Wii homebrew
guide, of course), don't update. The Wiibrew folks will hopefully come up with a patched solution that allows you to upgrade without the ill affects. Man, I hope we didn't jinx Wii 'brew by calling it "relatively stable!" [Wiibrew via Maxconsole]

Full message from Nintendo describing the update here:

Message from Nintendo

Wii Menu version 3.4 is now available for your Wii console. To update your Wii Menu to the latest version, please select the Update button at the bottom of the screen or select the System Update option in Wii System Settings.

With this update, Parental Controls have been enhanced, USB keyboard support is available for the Mii Channel, and system functions have been improved.

The Wii User Agreement, which includes the Wii Privacy Policy, has been updated. Because the updated agreement applies to you and your use of the Wii Network Service, you should view the updated version by clicking on the Wii icon located on the lower-left portion of the Wii Channel menu, selecting Wii Settings, accessing the Internet setting, and selecting User Agreements.

You may also view the updated Wii User Agreement online at http://support.nintendo.com

Because unauthorized modifications to save files may impair game play or the Wii console, updating to Wii Menu version 3.4 will also check for and automatically remove such save files.

**Please note: If you've updated your Wii Menu after 11/17/08, you may not need to update again.

Thank you for updating your Wii console!

Hanging out at sites like Giz may have instilled in you an insatiable, pocket-emptying gadget habit. But now we're entering a new era—the old guys on the TV are saying that soon we may not even have pockets, let alone money for them. Don't panic though: You've probably got a wealth of gadgetry sitting underutilized in your living rooms, closets and basements, just waiting to be given powerful new (not exactly authorized) features. For free.

I've collected the best firmware replacements, software mods and homebrew hacks from the DMCA-flouting, EULA-hating frontiers of gadgetland that'll breathe new life into your stable of hardware and maybe—just maybe—let you feel that lusty new-gadget rush again.

Turn Your Xbox, Old PC or Apple TV into a Genuine Media Center

Xbox Media Center is about as refined as an unauthorized hack can get, playing back virtually any audio and video format, running a bevy of console emulators and still playing your Xbox games. To be honest, this should almost be viewed as a natural update for every Xbox, which at its core is a slow but functional PC with an easy TV connection. (Any actual PCs you have lying around can run a PC-ported version of XBMC.)

Boxee is a very slick fork of the XBMC project for Mac, and it's available for Apple TV. As shipped, the Apple TV works fine within the closed iTunes ecosystem, but Boxee's support for virtually every video codec and free online video like YouTube, CNN, BBC, and Revision3 will suit your new, more destitute lifestyle a bit better.

Difficulty: Easy to Moderate. Installation is pretty straightforward in most cases, with simple Boxee and XBMC setup programs available for Windows, Mac and Linux. Before you load XBMC, though, you have to mod your Xbox with one of these methods, many of which require a specific game. After that it's all install wizards and lollipops.

Installing anything on the locked-down Apple TV used to take some serious finagling, but there are now tools that will create an automated Boxee installer on a flash drive. Just plug the drive in, restart and you're good to go.

Make Over Your iPod, Archos, iRiver or Sandisk with Rockbox

It's hard to look at the current generation of media players and not admire their diverse capabilities and extensible software platforms. That's not to say that your 5th-gen iPod doesn't play back music perfectly well, or that your iRiver H10 still isn't a kickass media player, but they do feel a bit dated. Rockbox replaces your MP3 player's operating system with something more substantial, effectively making it a completely new device. You get endless codec support, advanced audio options, dozens of games, useful apps like a calculator and a text editor, plus you can choose from tons of different interface skins for a unique look and feel. Rockbox's tweaking possibilities mean you will earn admiring "what is that?" questions from friends, and it won't cost you a thing. If your player isn't supported yet just hold on—everything from the Zen Vision:M to the Toshiba Gigabeat S has a fairly active dev team.

Difficulty: Easy. Rockbox has an automated tool called the Rockbox Utility available for Windows, Mac and Linux. It does the work for you. Even better, it often automatically configures your player to dual boot with its original OS.

Convert Your PC or Notebook Into A Much More Expensive Mac

It's undeniable that Macs are too expensive. For many, they are considered a luxury item whose added cost doesn't justify the benefit. Luckily Apple's switch to an Intel platform opened up a world of unauthorized OS X installations which can turn your existing PC into a powerhouse Mac Pro workstation, or morph your MSI Wind or Asus EeePC into the Mac netbook that should be in their goddamn product line anyway. Check the hardware compatibility list to see if your PC is eligible for the upgrade.

Difficulty: Moderate to Hard. If you're not morally opposed to downloading iATKOS and Kalyway, which are pre-patched Leopard install DVDs (this is bit torrent territory), then the process is much like installing any other OS. If you insist on building your own patched install from a DVD you own, then, well, good luck. Always check hardware lists first, though, because driver support is everything.

Flash Your Crappy Router Into a Top-Line Piece of Hardware

The DD-WRT project exists for a simple reason: Most routers are physically very similar, but are priced differently because of functionality derived from software. The DD-WRT firmware unlocks the potential of the most basic routers out there—too many to name but damn if yours isn't on the list. As it turns out, your budget model is kind of impressive: Program-specific traffic throttling, professional level wireless security and radical signal boosting are just a few of the dozens of new features that can be enabled.

Difficulty: Easy. If you can't manage this one, then you don't deserve a router—installation just takes a few clicks on the device's default configuration pages. A word of caution, though: Make sure your router configuration page is totally compatible with your browser before the operation, as some choke on Firefox and can botch firmware upgrades. Stick to IE if you have the choice.

Download Updated Maps For Your Old GPS

I'm referring of course to capital 'D' downloading here, mainly because at the moment GPS map updates are a racket. You could spend hundreds of dollars on map data that is freely available on Google Maps, Microsoft Live and MapQuest, among others, or you can just, you know, not. Map packs for Garmin, TomTom and Magellan units are floating around torrent sites and usually don't require much more than a simple CD image mount and run routine to set up. (Guilty conscience sold separately.)

Difficulty: Easy to Moderate. If you're just running a copy of a CD, then you'll be able to use the installation wizards. Some more involved methods for Windows CE-based devices require some SSH file transfers, but these are relatively rare.

Jailbreak Your iPhone for Wi-Fi Internet Tethering

Two internet plans are enough, but to sign on to a mobile internet contract when you've already got unlimited iPhone data feels kind of stupid. Jailbreaking your iPhone is now about as easy as performing a firmware upgrade, and there are actually multiple tethering apps. PDANet and iPhoneModem both work a treat, but keep in mind that excessive usage could draw AT&T's attention and ire: Tethering is not allowed on the data plan, even though it works fine. Both apps are available in Cydia, where you can also find a limited assortment of other apps that don't have a place in the app store.

Difficulty: Moderate. Jailbreaking can be managed through the Dev Team's fantastic Quickpwn tool, but it does take a few minutes and can go wrong if instructions aren't followed closely. After jailbreak, Cydia and Installer fill the role of the gray-market app store, functioning as simple package managers that are arguably as polished as their more legitimate younger brother.

PDANet and iPhoneModem take different approaches to tethering, but neither requires more networking expertise than it would take to, say, set up a router.

Turn Your Wii Into a Free Emulation Machine

It's more than a little infuriating to have to repurchase your childhood library of console games from the Virtual Console, especially when free PC emulators and accompanying ROMs abound on the old intertubes. All you need is a copy of Legend of Zelda: The Twilight Princess, an SD card and an SD reader and you're ready to install A Boy and His Blob: Trouble on Blobolonia, which is pretty much all anyone has ever really needed since this whole "Video Gaming Television Machine" thing got under way in the first place. Throw in extended media playback and some helpful widgets for an extra value-add.

Difficulty: Moderate. This is one of the only hacks here that needs additional hardware to work, even if it's basic. The good news is that once you find a copy of Zelda and load up your SD card, the process pretty much takes care of itself. Further app installs are taken care of through a intuitive dedicated channel.
