CustomizeMii is a 100% legal custom Channel creator for the Wii.

Changes:

Added CustomizeMii Installer (by WiiCrazy / I.R.on)
Fixed rough edges (artifacts) on images (will be fixed automatically)
Replaced the TPL preview window with the one from ShowMiiWads for easier handling
Added loop prelistening to the BNS conversion window (only for wave files)
Added drag & drop ability cause the file dialogs kept bothering me
Improvement in startup speed (thanks shadow1643)
Added creation/last edited time (only for CustomizeMii 2.1+ channels)
Added a button to translate the word “Channel” to every language
Improved detection of required TPLs
Little improvements and fixes
Changed the complex forwarder to be more configurable (choose any path you want)
ForwardMii is now bundled with CustomizeMii
