First off, I'm sorry to start a new topic. There are simply so many about Wiiflow, Metroid other M ... I softmodded my Wii to play backup discs. I changed IOS249 to a custom one, as directed in this video (which basically shows you how to install NeoGamma). This worked like a charm for my Wii. A Japanese Wii runing 4.2J. Plays many backup DVDs! Next I wanted to play Metroid Other M. As you know it's too big for single layer DVD, so ... Made a partition on my external hard drive, formatted that to FAT32 and then to WBFS type, using WBFS manager. This seemed to get me in the right direction, because USB Loader GX recognized the file. But it would not play it. I watched this video. But my USB Loader GX does not look the same! In fact, the settings did not allow a choice of IOS. Metroid tried to load but I got a black screen, with the Wii-mote "working". I took USB Loader GX off, and tried WiiFlow. WiiFlow does not find the file at all. I get the "WBFS_Open failed: -1" message. I read this thread, however I cannot even find a wiiflow.ini file on my SD! Other info: I am running WiiFlow through HomeBrew Channel. I am using a Japanese Wii on 4.2J. Backup discs successfully load, Japanese games or US games. Both Japan and U.S. use NTSC video. I tried another .iso, but the problem is not isolated to Metroid. I get the same error message in WiiFlow. WiiFlow wiki claims I only need cIOS249, and a few other things. I have heard of cIOScorp, and if you recommend it, a guide to installing it would be greatly appreciated. And finally, thanks to you all. I've worked through many problems before, by only reading and not posting.
