    When I Open USB Loader I press Super Mario Galaxy More ( Super Mario Galaxy 2) and a black screen appears above the option and start buttons. Then I press start and it returns to Homebrew Channel. I checked the SHA with Wii Backup Manager and the ISO is ok, i think because no errors appear. What can I do?

    That's where the game banner is supposed to be. Sounds like a bad rip.

    What is a bad rip?

    It can be two different issues, or the same.

    USBLoaderGX read the animated banner from the game file, and extract it to keep a copy on SD or USB for faster loading of the loader's interface.
    If the banner was badly extracted, a "bad copy" is stored on your SD or USB and will always be used and displayed as black screen, instead of retrying to read the banner from the disc.

    solution : delete the banner manually from cache_bnr folder, the one with your game's TitleID.bnr


    when the banner is bad, it doesn't necessarily mean your game is bad, but most of the time it is.
    so, if the problem was the extraction step, and the loader did a bad work, you get a black banner, but the game should work. in that case, it's only a loader's issue because your game works.
    If you have a black banner and your game doesn't work, the issue is not the banner extraction from the loader, but really that your game is bad, unreadable, corrupted, etc.

    So, you said WBM could check md5/Sha1, and reported it as good ?
    this is strange.
    is it an official game, or a modded one ? (added, custom levels, etc.)

    Did you check the ISO on your PC, or the WBFS on your FAT32 Wii HDD ? be sure to verify the one the loader will use.



    PS:
    a RIP (or a dump) is the action to make a copy of a physical device to binary file.
    Wii Disc -> Wbfs file
    a bad rip, or bad dump, or corrupted dump, is a bad copy.


    Personally, I prefer using the word "dump" as I always used "rip" for another meaning. a rip for me would be a modified ISO with deleted content to make it smaller (replaced video with dummy, etc.). ripping being action of removing, cutting, tearing. while dump is a full clean copy.
    I think it's just me who think like that, as rip is action of extracting from the original source : TVRip, CDRip, DVDRip, etc.

    I tried 5 different iso but none works. Then I tried using other loaders like CFG and WiiFlow. when I try to open the game CFG tells me: WBFS error:this is not a wii game. But when I try to open the game with WiiFlow the banner of Super Mario Galaxy 2 appears but when i load it the screen becomes black and and I have to restart the console.
    I do not know where the problem is because the Mario Galaxy wbfs file works on the Dolphin emulator.
    But I do not think it's right that indicates that mario galaxy has partition ??? and cios 0 in the picture.

    at least, wiiflow detects there's a problem instead of trying to load and crash.
    dolphin, being an emulator, is always less strict on errors and file format, there are more workaround bugs because it doesn't use the real hardware, so it rarely crashes.

    You are right, WBM not detecting the "G" partition is the problem here, and the fact it requests IOS slot 0.
    Is that game official or it has a user mod/patch applied to it ?

    I would try that file with Wit, to check its internal partition layout and data table.
    but, it clearly has something wrong.

    my WBM version doesn't display the requested IOS, it's 1.30 instead of 1.49GB (you probably still have the update partition, or more data than expected).

    really, I do not know what to say. I tried to put the same wbfs with Wii Backup Manager in another USB and the game works on USB GX.
