- 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.
