WIIKEY FUSION RECOVERY IMAGE v1.2 - 2010-06-21
----------------------------------------------
---------
IMPORTANT
---------
THIS IS A RECOVERY IMAGE. IT IS INTENDED FOR USE RECOVERING YOUR
WIIKEY FUSION FROM A BAD FLASH. RUNNING THE RECOVERY DISC IS MORE
COMPLICATED THAN RUNNING THE REGULAR UPDATE DISC SO, WHENEVER
POSSIBLE, PLEASE USE THE UPDATE DISC IMAGE AT
HTTP://WWW.WIIKEY.CN.
-------------------
General Information
-------------------
1) To apply this update, you will need dump it to a SD card as RAW data
This means that you cannot use any filesystem (such as WBFS, NTFS or
FAT32 etc etc).
2) To add the image to an SD card, you will need to use 'dd'. Using 'dd'
varies from system to system, with Unix-based systems being the easiest.
------------------------------------------
* WARNING * READ THIS BEFORE YOU PROCEED *
------------------------------------------
'dd' stands for 'device dump'. Running 'dd' literally means that you will
be writing all of the data from the .iso image directly onto your chosen
device (the SD card) without any filesystem.
Because this is a command-line based program, you must take extra care to
write the data to the correct device. IF YOU CHOOSE THE WRONG DEVICE, YOU
COULD END UP ERASING ANOTHER STORAGE DEVICE ON YOUR COMPUTER, SUCH AS YOUR
HARD DRIVE!
-----------------
Software download
-----------------
If you are using Linux or MacOSX, then you do not need to download anything.
However, if you are using MS Windows, you will need to download a copy of 'dd'
from
http://www.chrysocome.net/downloads/dd-0.5.zip -- you will then need to
extract the .zip archive and put 'dd.exe' into your path or launch the 'dd'
command from the directory that you extracted the .zip file to.
-----------------------------------------------------
Instructions for adding the .iso image to the SD card
-----------------------------------------------------
1) From the command line, identify your SD card device by typing:
Linux: `cat /proc/partitions'
(use the device name without a partition number;
ie: '/dev/sdc' and not '/dev/sdc1')
MaxOSX: `diskutil list'
(use the device name without a partition number;
ie: '/dev/disk1' and not '/dev/disk1s1')
MS Windows: `dd --list'
(use the device with 'Partition0' appended to ensure
correct operation in MS Windows;
ie: '\\?\Device\Harddisk1\Partition0' and not '\\?\Device\Harddisk1\')
2) Once you are sure which device is your SD card, you can type the
following command. BE VERY CAREFUL HERE:
dd if=wkf_recover_1_2.iso of=<your device> bs=1M
Here are some examples of what you may type:
LINUX, with /dev/sdc as your device:
dd if=wkf_recover_1_2.iso of=/dev/sdc bs=1M
MAC OSX, with /dev/disk1 as your device:
dd if=wkf_recover_1_2.iso of=/dev/disk1 bs=1M
MS WINDOWS, with \\?\Device\Harddisk1\Partition0 as your device:
dd if=wkf_recover_1_2.iso of=\\?\Device\Harddisk1\Partition0 bs=1M
3) After the process has finished, the update is ready to apply to Wiikey Fusion.
------------------------------------
Applying the update to Wiikey Fusion
------------------------------------
1) With the Wii switched off, insert the SD card into the Wiikey Fusion
SD card reader and then power-on the Wii.
2) Run the update by launching the GameCube 'disc' in the disc channel
3) After the update has completed, remove the SD card and disconnect the power
from you Wii. THen, reconnect the power and start the Wii as normal.
4) You can verify that the update was applied properly by looking at the
version number at the top right of the config screen.
