Michniewski and Tantric updated their SNES9x port to Wii and Gamecube once again.

Changes:

New GX-based menu, with a completely redesigned layout. Has Wiimote IR support, sounds, graphics, animation effects, and more
Thanks to the3seashells for designing some top-notch artwork, to Peter de Man for composing the music, and a special thanks to shagkur for fixing libogc bugs that would have otherwise prevented the release
Onscreen keyboard for changing save/load folders and network settings
Menu configuration options (configurable exit button, wiimote orientation, volumes)
Configurable button mapping for superscope, mouse and justifier
New save manager, allowing multiple saves and save browsing. Shows screenshots for Snapshot saves, and save dates/times
Experimental hq2x filter, contributed by michniewski
