Add button to mount DVD drive. Not completely tested, but somewhat. *Tested and working* retail Wii DVD Wii backup Wii backup w/ alt dol (redsteel) Wii backup w/ alt dol & ocarina (redsteel) Wii backup w/ alt dol & WiiRD Retail & Backup forcing video modes Saving individual settings for games on DVD (only Wii as BC is loaded before any settings would be used) Display disc images for DVD games Loading GC games retail & backup (w/ working MIOS patch installed) I did change some stuff after testing GC so it might be broken. Theme stuff for the button is not tested and I'm not quite up to speed with ardi's changes to the theme stuff so it might not work. Changed images are not compressed or optimized.
