Well, I've tried everything to get help, and nothing, so I'll have to start this thread. I have read through the large thread, it's a mass of information, little of which I can follow, little of which seems to be about my actual problem. I have a WiiKey Fusion, it's installed,, updated to v1.4 firmware, working, games run fine from DVD-R, and SD card. My Wii is an older, white model. Runs discs great. Now, for Super Mario Bros Wii, this is not the case. I have 2 ISOs of the game, both PAL, one is a standard ISO, the other called 'pal_nsmbw_multi5', which apparently is a scrubbed or patched ISO. Now, both of these ISOs when burnt to DVD-Rs do not work, giving error messages, like 'an error has occured, reset the system' or even 'the system files are corrupt'. Both of these ISOs when put on a SD card using WBFS Manager 4, give the same error messages. If someone could just please give me some concrete information. Is NSMBW supposed to work on a WiiKey Fusion? If so, by burning the ISO to disc? SD Card? Given that every other game works, and I have multiple ISOs of NSMBW that do not, what could it be? According to the WiiKEy Fusion information, it should run this game, without any softmodding needed. Many thanks for any help, and for anyone who understands how completely impossible it is, trying to come to this as a n00b, and understand what people are talking about.
