I've recently updated USBLoader GX to Rev.1231 and now when I try to play N64 VC games from my emuNAND it says.... "Error: Launching emulated nand channels only works on d2x cIOS! Change game IOS to a d2x cIOS first." I load cIOS 251 for my N64 VC games because I patched it with Waninkoko's v-19 for increased compatibility. It's never been a problem until now. Why am I being forced to use d2x cIOS's?
