Wii Backup File System(WBFS) by Kwiirk.
WBFS is a simple file system to store wii backup in an efficient way on a harddrive.
=== Wii Filesystem ===
All Wii Games do not take advantage of the whole 4.7GB DVD.
A lot of WII dvd sectors are in fact never used, even if there is random encrypted garbage in it.
WBFS knows about the wiidisc filesystem, and will copy on the wbfs partition only the part that are really usefull.
The idea of ignoring unused wiidisc sectors is not new, and is implemented in the WiiScrubber tool.
=== Aknowledgement ===
wbfs is based on negentig, a tool from segher, that allows to verify and decrypt wii discs. a modified version
is included, that allows to open discs on a wbfs filesystem.
=== Disclaimer ===
WBFS is a filesystem tool that may damage you disc partition if you dont know what you are doing.
WBFS is in a early beta stage, a number of safety checks are not done, that may cause bugs.
Please save your data, and report bugs (please be productive, and explain exactly the problem)
The authors of the software decline all responsabilities on damage that can been done by the use of this software.
This tool is not made to encourage piracy, only use your own backups from your own games.
=== Usage ===
This version of wbfs only runs on linux, and will probably compiler and work on other unixes including MacOSX even if it has not been tested.
Before using wbfs tool, you must format your harddrive. use the tool gparted from linux.
make a new primary partition of type "unformatted"
If you dont know how to do it, then wbfs in its current form is not for you, forget it or you will lose data. Sorry.
I assume now that $PART is the name of your recently created partition ( e.g. PART=/dev/sdc2 ), and your working directory is the binary release of wbfs_linux
You must be root, or have read/write access to your partition ( "adduser disk" on debian and co plus relogging will do the stuff)
*init the partition:
./wbfs -p $PART init
then wbfs can find automatically your wbfs partition inside your disks.
*add an iso to your partition
./wbfs add
*list the wiidisc that are on the wbfs, you will get the DISCID, game name, number of wide sectors used, and number of GB used.
./wbfs ls
*count the number of wide sectors / GB available on your partition
./wbfs df
*build Homebrew Channel directories for all the games in your partition
This will actually make a directory for each game with the DISCID of the game,
copy the icon.png and boot.dol of the current directory, and make a meta.xml with the name of the game
./wbfs mkhbc
Then copy all the directories in the apps directory of your sdcard.
*remove a disc from wbfs
./wbfs rm DISCID
*extract an iso from wbfs
./wbfs extract DISCID
*create a standalone compressed version of one iso using the wbfs mechanism
./wbfs create
=== Programmers usage ===
wbfs is based on libwbfs, a library to handle wbfs discs.
Its usage is documented inside the header file libwbfs/libwbfs.h
The idea is that you only have to give libwbfs some function pointers that allow access to your partition, and original wii discs,
and you can then manage a wbfs partition.
Some basic access to wiidiscs are provided by wiidisc.(h|c), allowing to extract files from the wii dvd filesystem,
to change the partition table, and to find out which part of the wii dvd is used.
=== unimplemented features ===
*copy a wbfs file to your partition
./wbfs add file.wbfs
