Updating malaak homebrew channel
It can launch or install homebrew applications from an SD or SDHC card or via TCP/USB Gecko using Wiiload.
You can install the Homebrew Channel as part of the Hack Mii Installer by seeing the Installation part of this page. In the VERY unlikely case that your Wii gets bricked by the installer, this will let you know where you stand in regards to Team Twiizers.
However, if you just go ahead and install all available updates there's a reasonable chance your channels will update properly.
Pimp My Wii is designed to simply go through your Wii and update everything that can be updated, including support for the Wii U's Wii mode.
If you're running something earlier, though, you'll need to update your platform.
To install channel updates without installing a system update you will need a homebrew application designed to update specific Wii Channels while avoiding a system update.
You need to page through each possible update, choosing the ones you want, and then eventually you'll reach a point where it will update them all.
Some of the adventures Scumm VM supports include Adventure Soft's Simon the Sorcerer 1 and 2; Revolution's Beneath A Steel Sky, Broken Sword 1 and Broken Sword 2; Flight of the Amazon Queen; Wyrmkeep's Inherit the Earth; Coktel Vision's Gobliiins; Westwood Studios' The Legend of Kyrandia and games based on Lucas Arts' SCUMM (Script Creation Utility for Maniac Mansion) system such as Monkey Island, Day of the Tentacle, Sam and Max and more. See here for a list of SD and SDHC cards known to be compatible or incompatible. Apps on your USB storage device are stored like on a SD card. Note: The Homebrew Channel requires that you system have at least one unpatched IOS in order to guarantee reliable performance; we've received too many bug reports that were later traced to misbehaving versions of IOS.
In order to make icons for the Homebrew Channel show up, they must be in format with dimensions of 128x48 pixels. Copy it into the folder of the application under the name "icon.png" (e.g. The Hack Mii Installer will automatically choose an appropriate (unpatched) IOS to use when installing the Homebrew Channel; if you attempt to defeat this safety measure by replacing its IOS with a corrupted version, you may experience an "impaired HBC experience" (an upside-down screen or a warning message at every startup). As of 1.0.7, The Homebrew Channel is capable of theming.
With Wii SCU you will be shown a list of individual updates for your channels, plus some other updates.
Wii SCU has a simple interface but doesn't tell you what non-channel-specific updates need to be installed for specific channels to work.
If you've installed the Homebrew Channel then a Wii System Update could brick your Wii — one update was specifically designed to do so, with the side effect of bricking non-homebrewed Wiis as well.
