WiiFlow_Lite/source/loader/gc_disc_dump.cpp
fledge68 17fa36e898 -fixed displaying errors on source menu 
-removed vipatch, country patch, private server and cheats defaults from wiiflow.ini. no need for default/global setting for those options. they all default to off internally in wiiflow.
-now on file explorer menu pressing home btn returns you to device select so you don't have to keep backing up to get back to devices.
-fixed a few minor problems with game configs, especially gc games. now all game config options should work properly.
-now using bitwise operators and expressions on m_current_view to control which sources are selected.  no more source= under each domain. just sources= under GENERAL.
-replaced ocarina option from main settings pg3 with channels type option. no need for a global/default ocarina setting. channels type allows you to select real, emu, or both channels types for channels coverflow. which means no more pressing B on config icon to cycle thru the choices.
-fixed a minor bug when downloading covers
-changed newid.ini to use only one domain name "[NEWID]". this fixes a possible problem when downloading covers and using newid.ini and multisource.
-added install wad option to nand emulation settings menu. I know you can do it via file explorer but this makes it easier for newbies to find. plus you can select which nand to install to.
-fixed extract game saves.
-fixed extract nand and install GC game by stopping music and controller input while doing these functions.
-Install wii game is broke. added a error msg stating this and keeping users from using it. funny the code is almost identical to usbloader gx which works and wiiflow doesn't.
-now showing all btns on game selected screen. if wiiflow is locked a error msg appears stating this.
-changed makeDir to make the whole path not just one folder. thanks to usbloader gx code.
-added .ciso extension to gamecube list maker so you can use them with nintendont.
