Hacking wbfs2fat.py

PsyBlade · Nov 25, 2012

That is indeed wired.
Unfortunatly I don't have access to a Mac to test things.

Your best chance are probably filesystem checking tools.

Do you (or somebody else reading this) have access to a MAC and linux?

The only thing I can think of is that wbfs2fat creates only a single FAT table.
By default other FAT formating tools create 2 copys.
But using one saves space, is compliant to the FAT spec and the wii FAT drivers ignore (which leads to inconsistencys, which is bad imho) the others anyway

To create such an FS under linux use (MIGHT work on OSX too)
mkdosfs -F32 -f1 /dev/sdX
then check if it works on a Mac

can you upload the backup file to let me check for other potential sources?

I have access to linux, is that command non-destructive? I really dont have the storage space to make a backup of my wii drive.

Here is what i get from an fsck.

Code:

dosfsck 3.0.12, 29 Oct 2011, FAT32, LFN
Checking we can access the last sector of the filesystem
Boot sector contents:
System ID "wbfs2fat"
Media byte 0xf8 (hard disk)
      512 bytes per logical sector
    32768 bytes per cluster
        69 reserved sectors
First FAT starts at byte 35328 (sector 69)
        1 FATs, 32 bit entries

It's destructive but you could use a different device eg some usb stick
edit: use a partition (like /dev/sdx1)

fsck looks as expected

Hi Psyblade.

Having difficulty getting the prog to run at all have run from cmd line in windows but get error :

Error loading Python DLL: python27.dll (error code 126)

I installed python and clicked on wbfs2fat.py but that just pops a window up and then cloeses right away.
I then ran Python and dragged wbfs2fat.py into it and get:

c:\python>wbfs2fat.py

Traceback (most recent call last):

File "C:\python\wbfs2fat.py", line 12,

wbfs2fat.main()

File "C:\python\wbfs2fat.py", line 731

import gui.gui

ImportError: No module named 'gui.gui'

ANy helpm would be appreciated.

Which version of wbfs2fat?
Which Windows?

Both errors can be caused by missing files (windows/python27.dll or python/gui/gui.py).
Are you sure that you extracted all of them?
(Some packing tool allow you to run progams directly without extracting them manually first. But they only extract the one file you actually clicked.)

Thanks for the fast reply. Neither of those files are present. When I installed python I used the Windows installer so thought it would be a complete package.
Any idea how I can grab those files then?
I'm on w8 btw and latest version of your aPP

thanks

I did not mean files from the windows python installer, I meant files from wbfs2fat.

Unless you have experience with python it's probably easier to concentrate on the standalone version (the ".exe" one in the "windows" folder).
It does not need you to have python (or anything else) installed.

Heres a list of the folders/files included in the archive:
(If one or more are missing try things like extracting them again/using a different unpacker/downloading again)

Ok,,feeling pretty daft now. Just presumed that the 0.9.0 beta contained all the necessary files. Never even checked the 0.8.6!
Should be fine now I guess. Thanks a lot.

PsyBlade · Dec 9, 2012

Yes the update versions were meant to be copied over an older one.
While I did mention that in the post that anounced the beta I'm not sure if I actually did it somewhere else to.
I should better check the readme right now....

Upload one backup or debug file somewhere to and I will have a look.
They are in the folder from where you ran it.

Cheers. I'm just wondring if its coz I have multiple partitions on the drive, with my wbfs one being the second. The other partitions are formatted as 2xfat32 and1xntfs.
I've uploaded to Dropbox https://www.dropbox.com/s/dk5gbvek988no2x/windows.rar

Thanks for all your support - much appreciated.

PsyBlade · Dec 9, 2012

Other partitions should not matter.

I'm unable to recreate to problem.
Could you run it with a higher verbosity setting (-v for cli or "2" in gui) and post the output.
Make sure to run it as Administrator.

Some other info would also be helpfull
windows version and size of WBFS partition (from windows diskmanagement NOT a WBFS manager)

I think the problem is win8

but for the moment this is going nowhere
I need to try running it on a win8 myself
might need some days till I can do that
I will pm you once I have progress

maybe try it on a pc with a different version of windows

last thing you could try is running the python version
I don't have much hope for that but since you already have python you can try if you want
there are some python extensions you need (see readme)
in cli go into the wbfs2fat\python folder
there run "c:\python\python.exe wbfs2fat.py \\.\E: -m convert"
(you migth need to change the path of python.exe to the real one)
