    I remember reading about this a year or so ago... I recently am getting back into my gc/wii stuff and found this again (great work btw) but the wiki states it's for Windows, Mac and Linux, yet I'm not finding anything but Windows downloads.

    Do linux or mac ports exist? Would love to use this natively without cumbersome VMs in the way.

    When you say that NKit.iso is compatible with an actual GC, do you mean as a physical disc? Swiss hates them...

    It is written using the .Net framework which is a semi-interpreted language (and avoiding non-multiplatform extensions like the WPF was) - you can use Mono to run the exe directly

    My entire collection is .nkit.iso.

    By the way, you reported Smashing Drive as not working, but I just tried it and it's working fine?

    I do have it running in a vm for now. Seems to work fine as is, but if I get into this any more I may setup mono to use it for simplicity in the long run.

    What an amazing tool. Thanks nanook for all the hard work. Now I've just got to hope something as good comes along for OG Xbox images!

    XBox has been looked at by others. The junk algorithm is known and works. It's seeded by a value that has to be brute forced. This is only possibly for early discs where it was simple. It was changed at some point to a value that would take many years per game.

    — Posts automatically merged - Please don't double post! —

    Sorry for the delay with my reply. NKit needs good a valid FST to be able to process and shrink the filesystem. If files appear to overlap then the files and gaps are unpredictable. The fix would be for something to correct the FST before processing it with NKit. Only the disc editor could do this effectively. It could probably be rebuilt with overlapping entries duplicated. I would like to look at this image if possible to check it's not just a bug though.

    Ah I see. I guess this is something where even if distributed computing could assist, it's seen as not worth it (that is, storage capacity/cost ratio would likely improve at a faster rate than brute force completion could compete with). Ah well, I'll take the storage wins where I can get them :)

    Great job with NKit, the new UI is a big help for beginners. My main suggestion is add a standard "Open..." dialog to import games.

    I'd like to offer NKit games at Vimm's Lair but sadly they don't work with USB Loader GX which lots of people use. It would help greatly to be able to convert from .nkit.iso to .wbfs with a single app. Meanwhile I'm testing out .nkit.iso downloads but to prevent complaints I may need to stick with .wbfs until USB loaders support NKit.

    I agree and it's on my list ;-). I have a few things on at the moment, but wbfs output and ciso input are things I'd like to add.

    Wiimm told me that the image is fine, so it's probably just a bug. You can try the latest version here: wiki[.]tockdom[.]com[/]wiki[/]Wiimms_Mario_Kart_Fun_2019-10

    Hi.

    I've been trying to use your app to convert nkit isos from Vimm's Lair back to iso format, and after trying a lot of ways to make it work I just keep getting this error:

    Use the convert2iso tool, not the recover2iso one...

    i am attempting to convert 8 .nkit.iso images back to .iso. i get read verifiedfailed errors on all 8 of them when running converttoiso.exe or nkitextractionapp.exe. selecting convert or recovery makes no difference. i'm rather frustrated.

    If you get the message "!! Update partition *_F9D11773 missing" It means the update partition was removed and needs to be present in one of the Recovery folders to Verify successfully. In this case the file will be named <something>_F9D11773

    When nkit extracts the partition it will preserve it in the Recovery folders. If people are sharing these custom images that need to be converted back to iso, it would be best to not remove the update partition or for it to be available.

    Use ConvertToIso to comvert images back to ISO also.

    Hi, nanook.

    I'm aware of the missing partitions. I've extracted some of them out of some working isos that I have. But still I haven't found the one I need for the game I'm trying to convert. lol

    As you can see from the screenshot, I'm using ConvertToISO.exe, is that what you mean?

    My message wasn't aimed at you directly. :-) I was trying to cover off a few recent similar messages.
    The file you require is 35900F41E235762320A2BC9ECBA23068BB754943_N_5A7E2CD4. It's 2MiB

    You should be able to extract it from any of the 481 images that contain it. ;-)

    Oh, ok. Sorry.

    I'll try to extract some more update partitions, then. Thanks for your help.
