Ok, I have done my research here and there and havent come to a solution that will be able to help me here. Im using the latest USB Loader GX revision ( r844 ). I have no problems playing Resident evil darkside chronicles or new super mario bros wii, so I know this is the latest release. I have seen videos in youtube and read posts in other forums about that I have to do something with the alternate dol option in USB GX. Some say that I have to select : load from disc. Then restart the wii and see what will happen. I only have these options in the alternate dol setting: -Default -Load from Sd/USB -Select a Dol When I choose the last one, "select a dol" option appears below it and if I press on it, I then can choose which metroid prime I wanna load. It gives me the real names: metroid prime 1, metroid prime 2, metroid prime 3. Not r3me01, r3me02, etc ... I have all the other options on default, except for error 002 fix. I chose metroid prime 3 and it gives me " auto" ( metroid prime 1 and 2 are 780 and 781 respectively ). I have tried with error 002 fix in "yes", in "no/off", and in "anti". They all give me a frozen black screen with the error message that I need to remove the disc and restart the wii. Its important to say that I dont have problems loading metroid prime 1 from it. Metroid Prime 2 just gives me a black screen and then the wii restarts automatically. Metroid Prime 3 gives me the frozen black screen with the error message. It is an ISO with 7.45GB, and I have a 4.0U with cios38rev14 installed. I have read that rev14 doesnt support dual layer disc dumps like mpt, but I dont think thats the case because ssbm works perfect with it through my western digital external hard drive. By the way, I saw a video on youtube seeing a guy using USB Loader GX r714 and using the "load from disc" option, then making it to work ( or was this using a dvd copy? ... Im not sure ). Please HELP me!!! =( EDIT: Will the Block IOS reload option in USB Loader GX make a difference here?
