I swear I've searched and searched for this problem and I've never seen anyone else with it, so here goes: Using a White Wii 4.3u USB Loader GX v3.0 (Rev 21008) d2x v8 final base37 I have a 500 GB Seagate Backup Plus, formatted into two partitions: 100 GB Partition - NAND (Fat32 32k cluster) 400 GB Partition - NTFS Formatted using EASEUS Partition Master Home Edition I used the USB Loader application's built-in NAND dump method, and attempted to load Mario Kart 64, which was loaded onto my real NAND using the Nintendo Shop Channel, from where I purchased the game. I select the Emunand channel option in category view (so that it only shows channels installed on my emunand), ensured that all related paths were correct (USB1:\nand\ for both Emu Save and Emu Channel), enabled Full emulation for both channels and saves, and choose to load Mario Kart 64. The game loads just fine, so I remove it from my real NAND, using the Wii System Menu, not using any homebrew managers or anything of the sort. Go back to USB Loader GX, attempt to load Mario Kart 64 (from the EmuNAND, as it no longer shows up on Real Nand channels), and after clicking to load Mario Kart 64, the system reboots the USB Loader GX software (or Wii System Menu, if that's selected to return to). I can't figure out why the loader is targeting my real nand when I select EmuNAND channels in the loader, but it is this way for all channels and games.
