The Wii Homebrew Launcher by developer hell_hibou is finally updated once again (previous version here), this time beefed up with features and improvements such as the addition of background music and changeable fonts in themes and PNG support, among others. Check out the translated version of Wii Homebrew Launcher v0.5's changelog (courtesy of our favorite weblator):

• The graphics engine has been rewritten
• Support for PNG (no layer alpha)
• The message "Press A or (1) + (2)" can be translated
• Initializing the Wiimote is a simultaneous loading data
• Adding background music (integrated into a theme)
• Possibility of creating a 'slideshoot' for channels
• Support format fraud (beta)
• Possibility to change the font via a theme

As always, you can download the homebrew launcher through the download link below. There is a readme file included with the download, but since it's written in French you may want to run it through a translator first.
