WiiSCU by Wack0 (mod of IOS51+shop by tona) – powered by PatchMii. The application gives you the option to install new versions of channels and IOSes without touching the system menu.

Changes:

Added code for debug purposes.
No more ‘epic fail’ — now it shows what patchmii returns.
IOS51 and Photo Channel 1.0 support removed.
Added an option to exit to the Homebrew Channel.
News/weather channel now installs HAFx/HAGx as well as HAFA/HAGA (using gamedisc region).
Added sysconf.c to determine region to install news/weather channels.
Tidied up code a bit.
