WiiScrubber

Information

A useful app that allows you to 'scrub' away the garbage data of Wii ISOs and in most cases drastically reduces the size of the ISO. However this is not just for smaller storage, the ISOs still work on the Wii AFTER being compressed. The project is still in development. Newest version is v.10a beta.

All credits go to Dack for making this program, and how to use it.

Purpose

It allows you to:

1. Open up the Wii iso's and extract individual files from them.

2. Change the iso so that unused areas are overwritten with 0xFFs. This has the effect of then making the ISO compressable.

Required

You need:# You will need a copy of the ubiquitous "key.bin" in the same directory.

You should not need to install any extra runtime files.# A descrambled wii iso
Plenty of disc space
A fair bit of time.

Usage

How to use:

Copy the key.bin file to the same directory as the exe.
Load the software.
Load the ISO file by clicking on the 'load iso' button
What the program is doing appears in the bottom window
Disc filelist appears in the top window as a standard treelist
Name of game and size of the data on the disc appears in top right

1. How to extract files:

Only one at a time at present
In the treelist click on a file to select
Right click the mouse button
Select 'Save' from the popup menu
The fields on the filename shown are: name, partition, Offset into decrypted file, Filesize

1. How to scrub the disc:

Click on the clean and save button
This creates a copy of the loaded ISO with the same name but (compress) appended to the name before the .ISO part (so SPM.ISO would become SPM(compress).ISO).
You still need 4.5 Gig of storage at this point but can specify which ddrive etc. to save it on
Compressing this image should give you a figure close to the size of data detailed earlier

Updates

Changes from 1.0:

1. Way of scrubbing changed slightly so that the sector crypto header is left unchanged. This makes it a bit more difficult to detect but lessens the compressability. 2. Disc Filename display corrected so titles like MoH2 show correctly ;)

Changes from beta test version: 1. Key file now only needs to be in the same directory as the program 2. A progress bar with cancel option when you start scrubbing 3. appended file name changed to (compress) to avoid confusion 4. Clickable URL of gbatemp in about box.
