*add loading of wii games / nand channels / emu nand channels in all combinations into one list *add button on main view for quick choice between the combinations of the three *add "Real Nand" or "Emulated Nand" text on the game window prompt when starting a channel *removed the need of a cIOS to launch the loader (if anyone uses it with IOS58 for whatever reason). The warning that a cIOS is needed is still present. *removed support for both usb ports at once on hermes cIOS. Each can still be used individually but only one at a time. This is done because of some bugs in the new ehci module which make some games unbootable. The ehcimodule is now reverted to the last working one. Need feedback if the games work fine again. *some preparations for the upcoming stealth mode feature of the d2x cIOS *isfs is now initiated once and deinitated when cleaning up only (instead of the whole init/deinit every single access) *removed choice for emulated nand channel modes. Emulated nand channels always need full emulation which is now always used on emu nand for channels. *removed unused settings for channels from the per game setting *changed default partition to 0 when starting with fresh settings (instead of -1 wtf?)
