Hacking wbfs2fat.py

[PsyBlade]

Whats the fucking deal with you people?

Im willing and able to help with problem.

But if me asking for more details or the backup file cause you suddenly vanish in a puff of bad smoke, never to be heard of again
then please do not ask me for help. It would just be a fucking waste of time for both of us.

Im OK with people that are not able/willing to provide that info (even if I think "not willing" is stupid and probably can't help you).
Just tell me that. I will see what we can do.
Or if that request is such a big insult to you that you don't wan't my help anymore then tell me that too.

Don't just fucking leave without me even knowing. That just gets me pissed of at people asking support.

BTW: Please post support request here, not as PM

Hi great program My friend told me about it and i decided to convert my wbfs drive. I seem to be running into a wall with the conversion part. I get this far then get a ERROR

W2F: checking for WBFS
W2F: analysing WBFS
W2F: creating FAT filesystem
W2F: creating placeholder Files
W2F: linking used Blocks to Files
ERROR

I decided to check the wbfs with wiimms wwt and i got this.

C:\Program Files\Wiimm\WIT> wwt CHECK w:\
*****  wwt: Wiimms WBFS Tool v2.07a r3955 cygwin - Dirk Clemens - 2012-07-14  **

!! wwt: ERROR #17 [NO WBFS FOUND] in AnalyzePartitions() @ src/wbfs-interface.c#

I'm running windows xp pro, the hdd is 500gb with 250gb partitioned as wbfs and the other is fat32. Any help I can get would be appreciated, thanks.

Thank you PsyBlade for updating your great tool

 

[PsyBlade]

first try running wbfs2fat 0.8.6beta3 (or newer)
from http://www.unix-ag.uni-kl.de/~t_schmid/wbfs2fat/
it will still not work, but it will create a file called "wbfs2fat.debug"
please upload it somewhere before continuing

try running "wwt check -v"
-v means verbose and tell you more about what is going on
and running it without a drive parameter should cause it to check all WBFS partitions it finds
(wwt's drive selection needs unix style notation not windows drive letters (stupid, I know))

fixed in beta4 (uploading right now)

was a stupid bug on my side that was triggered by not having a game located in the beginning of the disk

Did the Windows version get pulled down? I'm having no luck finding it.

Also, wasn't one of the benefits of WBFS reduced file sizes?

 

[Cyan]

the games have a reduced file size on FAT32 or NTFS too, they can be scrubbed by removing unused data, and the file is renamed .wbfs instead of .iso

If the file .wbfs is > 4GB, it's then split into another file .wbf1 so you can have big games on FAT32 too.

 

[PsyBlade]

There only ever was one download for wbfs2fat.
One archive containing two folders.

The python folder includes the real program as written by me.
That same code can run on Windows, Linux and Cygwin (provided you got python installed).

Aditionally there is a windows folder that contains everything needed to run it on windows bundled together.

I thought about splitting it because the bundled version makes up 99.8% of the downloads size but I never got around to do it.
Most people will probably want that one anyway.

Yes WBFS can save space by storing only the used parts of the game.
But that still applies to .wbfs files. (They are marginally larger, probably 2MiB)

thanks so much PsyBlade. what a great tool!! Amazingly fast too.

 

[PsyBlade]

I added some code to create an MBR on unpartitioned drives converting them into partitioned ones.

While somewhat uncommon it is possible to have a filesystem directly on the disk without a partition.
Personally I think its preferable to partition the drive even for a single partition setup.
But I read some claims that people have WBFS without partitioning.
wbfs2fat converted such WBFS to FAT32 fine, but Windows is afaik unable to read them (Linux reads them fine).
I now added an option to create a MBR with a single partition containing the resulting FAT32.

As this was part of general overhaul a regular version with this feature might take some time.
Should you want to give it a try regardless of some edges, post here and I will upload a snapshot.

edit
uploaded 0.9.0beta1
DO NOT RESTORE THE BACKUP MANUALLY WITH WBFS2FAT IF YOU USED "CREATE MBR"

 

[sebastien]

Thanks so much all who helped ! I will go and try that and see how it goes!!

Really appreciated!!

What a brilliant tool, worked absolutely flawlessly. Once again I am blown away by the by the wii gurus who put their time in making such tools.

 

[NewFang]

I'm having a real problem with this. I finally figure out how to use this and it reads.... "WBFS corrupt". I tried using wwt verify and it say "No WFBS drive detected". I lastly tried the ignore 6 option and I ended up with an "ERROR <class 'struct.error'>" Please help!

 

[PsyBlade]

if wwt can't even read your WBFS it's probably fucked up bad
sadly wwt is the only tool I know that can repair WBFS
maybe you find something else somewhere on the inet

if you upload the backup (prefered) or debug file somewhere I can try to find out what's wrong with it

 

[NewFang]

if you upload the backup (prefered) or debug file somewhere I can try to find out what's wrong with it

How do I do this?

Wii Back up manager reads all games fine.

 

[PsyBlade]

the backup file is "wbfs.DRIVENAME.TIMESTAMP.back" but might not be there if it crashed to early
the debug file is "wbfs2fat.debug"
both are located in the directory from where you called wbfs2fat

upload them to your hoster of choice and post (or pm) the url
maybe compress it (with eg 7zip) if you have something at hand

 

[NewFang]

PsyBlade, I don't even know how to do that. I'm not much of a tech guy (obviously) and need idiot/noob terms inorder to follow instructions. If you would like to go through PM so I'm not clogging up your thread with my issues lmk. If you are still willing to help. Thank you.

edit: I click the wbfs.debug file and it says windows cannot find that program. I cannot find the BACKUP file. Am I supposed to click the "restore BACKUP" option in wbfs2fat.exe?

 

[PsyBlade]

no don't use the restore
read http://en.wikipedia.org/wiki/File_hosting_service and do that to the wbfs.debug file
