WiiFlow_Lite/source/channel/nand.cpp
fledge68 9e85032382 * decided to officially commit my recent update patches * 
- fixed gc ciso games to show and launch via WFL. thanks CokeCookie for getting me to fix it. note banners do not show for ciso games unless you use a custom gc banner.
- added (for wii u vwii) to be able to select Wii U channel as the exit to choice either via main cfg pg 4 exit to option or home menu>exit to menu and select wii u menu. 
- removed priiloader and bootmii as exit to options when on wii u vwii
- added random select game option. manually edit wiiflow_lite.ini and under [GENERAL] set "random_select" to yes then while in wiiflow lite main screen hold B and press '-' to have WFL random select a game instead of random boot a game.
- removed region change from savenand emulation types. why? because according to overjoy's commit he said it didn't work yet. it was for a future version of d2x cios when davebaol added it to d2x cios. i looked at all the d2x cios commits from that date to present and didn't see that it was ever added. if i'm wrong someone let me know and i will add it back into wfl.
- made some small bootup changes in case of errors on bootup.
- made some changes to the way wiiflow lite handles emunand switching and other minor emunand code editing.
