Hello all! Thank you for having me here! As the title states, I'm having some great difficulty getting Gamecube backups to play through, well, anything. To put it simply, the issue is that whenever I try to load a Gamecube backup through USB Loader GX, it simply gives up and immediately returns the Wii to the Homebrew channel without hesitation. It only worked one time, and with USB Loader GX, and now it never does. This is the case with or without a Wii, or Gamecube, disc in the Wii. When attempting to load a backup through the DIOS-MIOS bootloader, the screen simply goes - and stays - black indefinitely, with or without a Wii or GC disc in the Wii. This also happens with WiiFlow. DIOS-MIOS is installed - before installing it through MMM or Waninkoko's WAD Manager, USB Loader GX did not report anything about DIOS-MIOS in its settings. After installing DIOS-MIOS v2.10 (not Lite), the settings regarding it show up. Pimp My Wii reports there being no cMIOS installed whatsoever, even after installing DIOS-MIOS through it. Further, I can't play retail GC discs normally at all (screen goes black through the default 4.3u Wii System Menu), after "installing" (because it may or may not have, given what Pimp My Wii says). My IOSes are all updated otherwise, with the ones that need to be Trucha signed are apparently signed. I can play GC retail discs if I NAND flash back to my backup made with bootmii immediately after beginning my Homebrew venture. To get Homebrew and Bootmii on my Wii, I initially followed the Complete Softmod Guide, then later tried Letterbomb after this, for whatever reason, refused to work. Still no dice. Wii games play absolutely, 100% perfectly in USB Loader GX, and save fine too, all on the default settings. They are all GAMEID.iso backups. GC backups will not show up in USB Loader GX if they are named game.iso and stored in /games/ on my USB (which is formatted to 32k). Rather, to get them to appear, they must be in the /wbfs/ folder with my Wii backups for them to show up at all (yes, even after altering the path settings for GC games to be listed under /games/, they still don't appear unless in the same parent folder as the Wii backups). My USB Loader GX version is the r1218_mod01 build, specifically because that build supports DIOS-MIOS and loading from a USB (which, again, works perfect for Wii games, but refuses to for GC backups, despite that being what DIOS-MIOS is for). I also have Priiloader, and Region Free Everything (tried GC-specific too) set, and d2x revision 8 installed to base 249, 250, and 251, on 56, 57, and 58 respectively. I've also tried changing individual game, and loader global, settings like forcing NTSC-U or English language, and 480p, TV patches, etc., to no avail. Nothing even tries to load GC backups, whereas the Wii backups work fine. They install and copy over to the USB with no trouble, and I have tried reformatting both my SD and my USB with fresh copies of the backups and loaders. To recap/TL;DR: 1. Wii games work fine on my USB, in the slot closest to the side of the Wii (like it's supposed to be), and save perfectly. 2. The Wii is a Black Wii, with bootmii installed as an IOS rather than boot2 (because that was the only option). 3. GC Backups won't work at all, despite having DIOS MIOS installed. 4. I've tried different loaders to no avail, except a single time in which a GC backup could be played early on. 5. Since then, it has not worked - selecting the games pulled up a black screen, trying to 'start' them results in an immediate and indefinite black screen (unless using USB Loader GX, which immediately returns me to the HBC). 6. GC retail discs don't work with DIOS-MIOS v2.10 installed. 7. I have Wii System Menu 4.3u. 8. The GC backups are NTSC-U, like my Wii. 9. All of my IOSes appear to be updated, with the appropriate ones Trucha signed. 10. Priiloader is set to Region Free Everything. I've tried having that GC-specific as well, to no avail. 11. USB Loader GX is using the beta build r1218_mod01 specifically because of its USB support to work with DIOS-MIOS. 11. I am NOT using DIOS-MIOS Lite. 12. My USB is formatted to 32k cluster size. 13. I've tried loader-wide and game-specific settings, such as Force-NTSC, 480p, and various TV/Video patches, to no avail. 14. I've tried reformatting both my SD and USB, just in case that may be the issue. No dice. 15. I've tried re-doing everything through using Letterbomb and various guides online, some calling for specalized WADs that also did nothing. 16. I'd be more than willing to zip a complete copy of my SD for someone to look at if it would help. 17. If you need anymore information, I'd be happy to provide it. With so much information out there that is vastly outdated and/or completely disorganized with regard to Wii Homebrew and loading GC Backups from a USB, can someone provide me with an accurate, up to date, step-by-step guide (or a link to such a guide that I may have missed), from beginning to end, to get GC backups to play from a USB (not SD)? I've been more or less pulling my hair out with the sheer number of guides that are supposed to make this work, but simply don't. Any help at all would be greatly appreciated. What am I doing wrong here, and where are the most recent updates (gammas, betas, alphas, even pre-alpha) for all of these Homebrew apps we need to get things running?
