Update: You can convert compressed ISO images (.ciso files) using this method, too…
If you need to translate a Wii DVD image from the newer .WBFS format (which has lovely sparce-file support) to an old-school .ISO image, well you can jolly well do so with Wii Backup Manager! Now, WBM is a really useful program so congrats to the author (xzxero) – but it uses non-standard GUI elements in that it uses what looks like the category list as a second main-menu, and this makes it a little non-intuitive to use. But in fairness to the author, the download page has a tutorial (which I didn’t find until after completing this post!). Still, it’s easy enough once you’ve figured that out. The entire conversion process goes like this:
1.) Grab yourself a copy of Wii Backup Manager. Version v0.3.5 beta 1 is the most recent version available at the time of writing, and although it’s Win32 only, it works fine in VirtualBox…
2.) Extract and launch it

3.) From the Files tab, click on what looks like the Add category title, select Files and go pick a .WBFS image from the navigation dialogue box

4.) Still in the Files tab, tick the checkbox to the left of your .wbfs image, and then click on what looks like the Transfer category title and select ISO..

5.) Pick where you want the converted .ISO file to be created and click the [OK] button

That’s it – job done! Transfer your ISO to your WBFS formatted USB drive and launch it as you normally would via USBLoaderGX or whatever your poison is… :)

Thanks for this it really helped.
Important!
The converting-part didn’t work ONCE if I didn’t use the Desktop as where the result should end up.
So a tip to you who just get red text under the progress bar: try choosing desktop as where your .iso file should go.
I came to thank, read this and was like, YEY!, I just picked desktop – as I usually do with like, everything.
You really helped me and a lot of people around the world! Thanks from Brazil :c)
I Make new file in Local disk D, and i called it WII. Than i make .Iso in that file and i did it, Of course, thats my first time to do convert, but than i saw your message. To burn now this game to DvD, or to convert it AGAIN on Desktop?
I think what SweO is saying is that Wii Backup Manager doesn’t work (i.e. it won’t convert ISOs) if you don’t specify the Desktop as the output location for the converted ISO/CISO/WBFS file. I haven’t ran into this problem myself so I can’t confirm it.
And to burn to DVD, you definitely want whatever Wii game you want on disc in ISO format (and not .ciso or .wbfs format). If you’ve already converted a Wii game to .iso format and it worked fine outputting stuff to your D: drive, then you don’t need to convert anything again.
You might consider too, that you have enough space in disk, or else it’ll show the red text. =) I was trying to convert WBFS to ISO, but then i did what you said, and it still didn’t worked, so i thought i might not have enough space in disk, then i deleted some programs, and it worked
Thanks a lot, flash drives are faster and great for the games you play the most but for the larger collections it’s nice to have a permanent copy on disc.
HDD is better.
NB: There is a later version now 0.3.5 beta out now that works fine on 64-bit OP (Win7).
kudos!
Thanks for this. Came up easily on a google search, and was incredibly useful. My wii became 1000% more interesting and useful once I softmodded it.
Thanks for posting this. What a great help.
Many thanks
thanks it works
Hiya
I’ve just installed a Wasabi DX in a friends Wii for them (they don’t want it soft modded). It’s running Firmware 4.1E and the Wasabi is on Firmware 3.0.
It works fine with backups from disc or ISO files but it won’t play any backups converted from wbfs to ISO (using the method listed above) then burned to disc. They’re all giving me Error #002
Strangely, this method works fine with an old Flatmod chip I have, but not with the Wasabi DX. Any ideas?
I wondered perhaps if upgrading the Wii firmware might help, but I don’t want to lose multiregion support on the Wasabi.
It’s not an insurmountable problem but it’s a pain in the arse because most of my backups are in wbfs format.
Any advice would be gratefully received :o)
Cheers,
Dave
Hi Dave,
Many loaders have an option called #002 Fix which will do exactly what it says on the tin =D
Look for that option in Wasabi and flip it to On. I’ve never used Wasabi DX, but the option’s available in things like USB Loader GX, WiiFlow and NeoGamma, so I’d imagine it’d be there somewhere – if not, choose a different loader which has the option!
Cheers!

works great for softmoded 4.3u thanks and keep it up
Thanks, it worked just fine.
I had a bunch of games in wbfs files that I can play now!
once i change my wbfs file to an iso, it becomes too big to fit into my hardrive, what do i do?? if someone can help me figure this out, i would very much appreciate it :( i’ve tried so many other methods and i’m hoping this is the last one :( :(
Hi Minnie,
Your hard drive is probably formated as FAT32, which has a 4GB file limit (so no single file can exceed 4GB in size), to allow you to store files > 4GB you’ll need to convert the drive to NTFS format. Or at least convert the partition where you’re storing your ISOs, assuming you want to use the drive both for homebrew (which I believe needs to be FAT32) and games (which as you’ve found out, need to be in a format which can store large files such as WBFS or NTFS).
Newer versions of USB Loader GX etc can natively read/write NTFS partitions, so you can run games from the drive if you wanted to.
Hope this helps.
When i do this this is what it gives me

WBFS file isn’t a WBFS file, or is corrupt? Have you tried launching it in the Dolphin emulator to make sure the file’s okay?
Compatibility list says it should run:
https://wiki.dolphin-emu.org/index.php?title=The_SpongeBob_SquarePants_Movie.
hey, thanks for the response r3dux!
my hard drive is actually WBFS format, which is why i’m not able to play wbfs formatted games, unless i use this program….is there anything that i could do to fix this?
for some reason its hard for me to get usb config to let me choose between partitions…. i wanted to play both .wbfs and .iso files, but i always end up only being able to view the iso files when i open my hard drive with any loader. so i figured i’d just use this program to convert wbfs to iso. but everytime i try to upload the game file after converting it, my hard drive refuses to accept the file because its too big..
To play any iso/ciso/wbfs files (i.e. games) you can’t just copy them to the drive, they have to be transferred to the drive, which puts them in the right format for playing.
To do this:
Once the disc image(s) have transferred they’ll show up in USB Loader GX / WiiFlow etc. and you’re good to go!
I’m using a WBFS manager for Mac and I can’t load wbfs files into the manager. It appears I do not even have an option to convert wbfs to iso; I’ve gone through all the menu’s and clicked on the possible buttons. When I click on “Load ISO” and I’m scrolling through my files I cant click on the wbfs file. HELP! There seem’s to be no tutorials for Mac users…
If you mean you can’t view the file to select it in the the Load ISO file dialogue:
In the file selection dialogue window there might be an option for which types of files are displayed *.iso, *.ciso – maybe you can change that to All files to allow you to select a .wbfs file? The option might be called “Show” or “All readable documents” or something like that.
If you mean’t something else:
Sorry – I’ve no idea, I’m a Linux monkey and know absolutely nothing at all about macs. Maybe you could (in order of least to most effort):
– Try and find some different WBFS conversion software that’ll do the job,
– Try running the Windows version of WBFS Manager through a copy of Wine (links: winehq/MacOSX using the WineBottler app),
– Copy the wbfs file to a USB drive of some sort along with the Windows version of WBFS manager, then find a machine running Windows (friend, school, work, library etc) and do the conversion on that machine, or finally
– Throw an old copy of XP onto a virtual machine ( via virtualbox or such) and try the conversion through the Windows version of WBFS manager that way.
One of these will do the job – it just depends on how much effort you’re willing to put in =D
Worked brilliantly – many thanks
hello again, i tried everything that you mentioned but its not working. i seem to get more and more confused as i’m trying to figure things out. im under the impression that i have a wbfs partitioned drive, because when upload my games, i use the wbfs manager for mac…but when i opened up the wii backup manager on my PC to convert the games, under the disk 1 option on the very bottom where the drive information is given, it says: drive n: WBFS folder (FAT32).. i guess since all my wbfs files are saved under my fat32 partition, tis reading it from there. but i want to be able to save it to the wbfs partition… i know i’ve been posting a lot here, but i find it so helpful! hope i’m not being a bother!
-minnie
i converted all my files to iso, then i transferred it to disk1 only to have all the files turn back to wbfs format…. sigh
Okay, let’s try this again…
– You can’t fit a file which is larger than 4GB onto a FAT32 partition, as has been discussed, therefore either the game images you are working with are less than 4GB in size, or you have at least two partitions.
– 2 partitions is a good number of partitions. It means that you can use FAT32 for things like Wii WADs, and applications and all other things that the Wii wants to read natively, and then the second partition (which is going to be in either WBFS or NTFS format) to store the game images, which can be (and often are) larger than 4GB.
– The only way I see the games being transcoded from ISO to WBFS format by Wii Backup Manager during the “transfer to drive” process is if the software is trying to tell you that the games MUST be in the WBFS file format to be successfully ran from a WBFS formatted partition, so it’s performing the transcode for you. I have no idea whether this is true or not – you’d have to research it. Personally, I keep my original ISOs backed up in .ciso format because it has sparse-file support, and I don’t care what format they are on the actual Wii USB drive because they work, which is the only aspect I care about.
– Wii Backup Manager has lots of nice documentation! Behold! Read!
Good luck! =D
thx for help! let the beer be with you…
finally!! i can play all my wbfs games!!!
THANKS!!!!!!!!
Is there a way for me to do this in Linux?
Wine does not seem to like this program.
I run it through Linux via an old copy of XP and VirtualBox. Maybe not an ideal solution, but it does the job :)
there is an incredibly simple solution for linux. the WBFS file is literally just a disk image, therefore what needs to be done is for it to be recognized as a device block.
just do this:
sudo losetup /dev/loop0 file.wbfs
(that’s losetup with a lowercase L)
then just open up wbfs manager, it should pick it up. there you can extract the iso from it.
after you’ve extracted it and exited out of wbfs manager be sure to run:
sudo losetup -d /dev/loop0
try this ones they are for linux
wiithon
QWBFS Manager
Wii Backup Fusion 1.1
Thanks for the tip – will check them out! =D
This program runs under wine. Worked for me perfectly – I use Arch linux.
Very useful, appreciated.
Many thanks for taking your time to build this tutorial, i was able to convert my wbfs files into ISO with it!
when i run this process of conversion and transferring the game title shows up on my usbloadergx with music playing but when i click on disc icon to load game get just black screen
That’s not related to the conversion process, it’s more likely related to either the cIOS setup of your Wii and/or the actual game rip you’re using.
Assuming the game rip isn’t bad to begin with, make sure your Wii has a suitable cIOS configuration for the specific game you want to launch to work (i.e. most are fine with 249, some need 222, some need a special combination 223 etc).
For more information, take a look at: http://www.wiihacks.com/wii-learning-center/18990-wii-cios-explained.html.
Hello i wonder if someone can help me.when im gonna convert the file to an iso from a wbfs i get 2 errors all the time.1.”WiiFatDrive.OpenVolume Error opening volume.The system cannot find the file specified”.2.”FilesToISOThread Unable to open file. Hope you can answer soon cause i really want to play some games on my wii i have only got 2 games working so far and on christmas it was 1 year from when it got modded so i really want to know so i can get more games.
Best regards/Wilnar
These both look like the same problem – try copying the .wbfs file that you want to convert to your desktop or the root of the C: drive ( i.e. C:\ ) and rename it to something really simple like “test.wbfs” and then try to convert it to an ISO.
I’m only guessing here, but it could be that there’s an extended ASCII character in the filename or in the path leading to the filename which WBFS Manager can’t work with (for example, an “o” with an accent in “Pokemon”).
Oh thanks for the help and quick answer r3dux but i actually got it remodded today and now i got usb loader (YAAAAAAAAAYYYYYYYYY)Well thanks for the help anyway and that you considered helping :)
Hi everybody, Can anybody tell me how can I load a .wbfs file to an .wbfs formated drive without having to convert it in .iso?!, as long as I have the .wbfs file why the work arround ?
You should be able to just use WBFSManager to do the transfer as the article states but using a source file in .wbfs format.
The only reasons for the workaround/conversion are:
– Back in the day I didn’t have the tools to transfer a .wbfs file to a wbfs partion so that it would work – but if I transcoded from wbfs to another format (such as .iso or .ciso) then I could transfer the games to a wbfs formatted drive and they’d work fine. I’d imagine most Wii “iso managers” will now do that happily, but there was a time when they wouldn’t.
and
– You might want to transfer the game image into a more “long-term” format, so that when the .wbfs format dies out and the tools to manipulate .wbfs files die out and no longer work on newer operating systems, then you’ll still have the disc images in an accessible format that you can work with. i.e. the .wbfs is rather niche, while .iso and .ciso are more universal and will likely be supported by tools well into the future.
Wii back up manager worked for me before, but now it wont convert wfbs. into Iso format, it tell it to put it in the desktop but still doesnt work…
Try renaming your .wbfs file to something really simple on the desktop like “test.wbfs” or such and try again.
Also, maybe try converting a different .wbfs file (if you have one) – it could be that the particular .wbfs file you’re trying to convert is knackered, or isn’t really a .wbfs file at all. To be sure you could check the file contents with a hex-editor or something.
Or, try using a diff converter: http://www.wbfstoiso.com/
Hope that helps – but keep in mind that if other .wbfs files will convert and it just so happens that the particular .wbfs file you want to convert is bad then there’s nothing to be done for it!
Very nice!
thank you.i was smacking my head against the wall but i read this lol.
Hi guys,
I know this topic is as old as the roman empire. But I have been looking for 3 hours now, and I cannot find any answers to my problem.
I have 5 games in *.wbfs image format and I am trying to convert them into *.iso format.
I have tried all kind of programs:
WBFS Manager
WiiFaBu
Wii BackUp Manager
etc…
but I am not able to convert with any of those.
WBFS Manager shows the imagefiles as red files and I am not able to move them anywhere.
WiiFaBu and Wii Back Up Manager will develop an error message.
Are all of those WBFS files corrupted? Is there any kind of small index file needed for identifying them as WBFS Image files? Or any other preferences?
Thank you in advance.
Hi Muh,
I’ve never had that issue with Wii Backup Manager – so they could be corrupt files.
To find out for sure, you could try converting a known good .iso to .wbfs and then try to convert it back – if it works, then your .wbfs files are probably corrupted somehow.
Also, it could be that you’re trying to convert the files on a FAT32 formatted drive such as a USB drive/stick? If so it’ll fail because you can’t create a file > 4GB on a FAT32 partition, so you’d need to copy them to a NTFS partition before performing the conversion.
As far as I’m aware you don’t need any kind of small index files w/ .wbfs.
Hope this helps,
r3dux
Can WBM detect WBF (window batch file) and convert to ISO because my file is in WBF?
Your game won’t be in Windows Batch File format – just try renaming the file to .wbfs, or .iso or .ciso or .rar or .zip and see if you can do anything with it.
If not, it’s probably just a blob of binary rubbish designed to waste your time and bandwidth.
thanks man, this works great also if you want to turn a huge .iso into a teeny weeny .wbfs file. THANKS!!!
This site saved my ass. Respect! <3
Thank You very much!!! Able to convert and burn now xD You save my life…….now i have to try and play it on the wii :o
Thanks
Hey, ive read i all the comments and cant find the answear, maybe im just to foolish too see the solution for my problem .
When i add a file i find the .wbfs that i need i add it in the wii back up manager and then it says
Adding files..
Total: 00:00:00 – 100 %
Finished
————————————— (a green bar)
test.wbfs
It says that its finished adding the file but the file isnt there it didnt show up what to do?
Okay, so you fire up Wii Backup Manager, and in the Files tab you click on Add | Files and point it at a .wbfs file – so far so good.
At this point Wii Backup Manager should display the file in its little list (ya know, with Game ID, Game Title fields etc).
Now, you should check the checkbox to the left of the file (in the list with Game ID, Game Title fields etc) and click on Trasfer | ISO and then give it a location (like the Desktop or such).
If you’re saying that this is exactly the process you’re following, and that it doesn’t work – I’m a at a loss. You could try converting a different .wbfs file maybe incase the one you’re trying to convert is corrupted and Wii Backup Manager can’t work with it. Or maybe try getting another copy of Wii Backup Manager (later version? older version?) and try your luck there.
Hope you get it sorted!
No thats not the problem, at least for now -_-
When i add a WBFS file it isnt even displaing it.
Then I’d say the .wbfs file you’re trying to convert isn’t a valid .wbfs file – download another .wbfs file and try to convert it. If that works, you’ll know your first file is broken/corrupt/garbage.
Yeah youre were right the file was broken but its weird i downloaded 6 .wbfs files and only one of them worked. Ok now ill atleast know.
Thanks for your help and awesome tutorial and thanks for answering so fast to my questions ! ;)
This might be a silly question but, after converting my file, is it supposed to be bigger than usual? I know there are certain size numbers to a file that has to be on an ISO to properly put it on a CD and then play it on my wii but this is much bigger, am I missing something or is it okay to just try and burn this big file on my disc and play it?
Yes, this is normal because WBFS has sparse file support while the ISO format does not.
Also, you’ll need a DVD not a CD to burn the image to, and if the disc image is larger than a DVD5 (4.7GB) you’ll need to burn it to a DVD9 (dual layer, approx 9GB) disc, if you have a drive which can do that.
cool thanks now my Legend of zelda twilight princess is now working thanks a lot
muchisimas gracias estaba desesperado
hey man how to convert iso 9660 to wii game iso (4.37).
coz my ben10 galactic racing i convert to iso 9660. then when i transfer into wbfs drive using WBFS mngr 3.0 no Results / no image add to wbfs drive. what should i do
Sounds like the file could be corrupt and WBFSmngr is silently failing the conversion (anything in the logs?). if I were you I’d try running the ISO version in the Dolphin emulator to see if it even boots.
Thank you so much!!!!!!
Thank you so much… Downloaded my fav TV show wipeout and it was a wbfs file instead of a disc image..thanks a bunch
