When I try to unscrub a scrubbed file, it asks for a DIFF file.
Where do I get this?
You get the diff when you scrubb a iso.
First question is 'why do you want a diff file"?
A diff file can be produced when you scrub a disc, but very few people do. The disc runs without being unscrubbed.
Here's the case:
I've downloaded a game for the Wii Excite Truck, and it was only 900MB to download.
The filename is Excite Truck PAL - wiiscrubbled.
And I've extracted it and now it's around 4.6GB.
How is it possible that it was only 900MB to download and now it's 4.6GB?
Because the scrubbing fills the junk space on the ISO with zeros, which compress very well.
You don't need to unscrub anything. Just burn the ISO and enjoy.
Edit: must hit add reply quicker.
It was explained when you originally asked about all this but we suffered language barrier issues.
Discs are 4. whatever gigabytes (that is how much they hold) and the whole space is written to. When they are dumped all the sectors are copied back.
Games do not have to take up the whole disc so junk data (which the game could care less about) fills the space.
However in the case of the wii this junk data gets altered and this means in nearly all cases it does compress very well at all using conventional methods.
Dack's tool takes this junk and replaces it with data that is simple to compress.
Okay, now I understand it FAST
Tnx for the quick answers.
