I have backed up my 1st-print copy of Metroid Prime 3 onto a USB drive using the latest USB Loader GX. I'm loading it using IOS 254, and the game is playing fine... ...up until I hit the Hidden Court room; it is a room with a giant stone golem held to a wall by strands of fuel gel, for those who might not remember it by name. Once I enter the room and after I trigger the Warp Hound fight, the game ceases to load files from the disc; I can't scan anything (it scans, but simply shows no information when it finishes) and I can't leave the room (I shoot the doors, but the previous / next room is never loaded off the disc. I can't figure out why exactly it's doing this. I've also tried playing the game with Wanikoko's USB Loader v1.5 (I know, old version). No difference. Has this happened to anyone else?
