Compressing softs????
Any softies that would compress a games of gbs into mbs(like 3 gb game into 700 mb)...
If not, how do the pirator's do so...
I've seen in shops San Andreas being sold in just a cd nd GTA 4 in 2 DVDs{I didn't jst c, I got them 2}... ;-)

Thats a little hard to achieve. As for pirates, they remove multimedia contents(i may be wrong).

7z gives a better compression ratio than rar/zip but the former is not THAT famous.

^he's right, there are a number of approaches, but usually they pull tricks like remove the video demos or reduce the quality of all the images and sounds.

game cd generally uses UHARC compressing tool, it is a command line program. you can give it a try.

1. They resample the videos to a lower quality.
2. Some/all of the audio is removed.
3. Some/all videos are removed.
4. After that, the files are compressed using UHARC (most common).
5. The resulting data is packed into a ZIP/RAR/7z file for release.

try UHARC...it is most used for compression of data......!!

San Andreas in CD not possible, the best compression-full game has been done by the reputed "KAOS" who got it just at 900MB.

7z gives better compression ratio than ZIP, but not RAR.

yup, in simple words. This is known as a "game rip."

Any proof for the same? In my experiments with both the file formats, I have found that on an average, 7z format consumes about 5-20% less space.

^Even i was speaking from THAT experience

(remember that magazine of yours?)
Anyway, maybe the results depend on the type of files/contents to be compressed and is not generic.

WinRAR wins rarely. When it does, it does by a small margin. Not worth the money we have to pay for it IMHO. 7-zip = FOSS and also > WinRAR.

Hi there,
As a new poster I am going to refer you to the Forum Rules Again.

* No Posts Related To Anything Illegal.
Do not post/link to anything related to hacking / warez / cracks / pornography, etc. Piracy, and anything related to it is not allowed on this forum. Exchange / sale of pirated software / music / games / movies, etc., is forbidden.

Do NOT post links to pirated content! At the moment I'm giving you the benefit of the doubt and hoping that you won't continue the same.

I once downloaded Hitman Blood Money which takes more than 2 Gigs on uncompress. But download size was about 400 or 500 MB. Mind it though it took me more than 1 hour to uncompress all the files.

The approach was using a mix of UHARC and Class inject files. UHARC works better on multimedia files than other compressors. But you will need a lot of MS-DOS batch files for this.

7z is far better than winrar in matters of compressing

^^ True, but I still love WinRAR. And it's bugware, so it doesn't stop working... gotta love it

While I actually can't say what the pirates do. But while uncompressing the games, if you look carefully the things happening :

1. They doubly compress files - one time using 7 zip & once using UHARC.

2. They generally delete cut-scene & intro videos which take up a lot of space.

3. They re encode the in-game music into something smaller to pack.

4. They use some sort of "file-injection". I don't know what it is or what it does.

i saw a cd of 700 mb containing full gta sa when you extract it it become 4 gb. the compression is used mite be winrar

UHARC does that, but i think 7-zip is the best. Try both and decide which gives better for your need.
