WiiMC-SS is a fork of WiiMC, a multi media player for the Nintendo Wii.

Release notes:

-Enabled ADX audio decoding

I mean this is a gaming console so why not support game music formats?
So far only ADX files from NiGHTS: Journey of Dreams seem to play incorrectly.

-GameCube controller support

Every button from the wiimote (Form Baton) is currently mapped.
Please note that there are still some things that require the pointer.

-The option to disable the H.264 deblock filter on a per video basis

To disable simply change the extension of your video to “.dash”.
Disabling this increases decoding speed a lot, but decreases visual quality, however depending on the video you can get away with it quite well. Keep in mind that the Netflix app for Wii does this for both main and baseline profiles.

-Added an option to enable the volume normalizer audio filter. (A restart is needed when changing from methods)
-Added an option to always zoom videos to 4:3 ratio. (H zoom should be ~133%, this setting only works if your Wii is set to 4:3 mode)
-Added an option to enable deflicker, 480i and 480p supported.
-Added an option to scale screen width to 720.
You will find these new options in the settings menu. For volnorm set it to “2” to enable volnorm method 2.

-Added Screen Burn-in Reduction support
To enable simply go to Settings->Global, it will dim the screen if the screen saver is active after 4 seconds.
This setting requires ahbprot disabled.

-Added an option to switch to 240p mode.
This setting can be found in the global section.

Thanks to Nintendomax for the news.
