Some help with these extensions??

[Prince_of_Pea]

Hi experts, I like to change the sound, the video, the subtitle and even the menus in my PS2 games, some i can do, and some i can't figure out how. Well im not expecting to be able to do this on every game I buy, but I would appreciate any help on how to decode, change and ultimately encode these extensions. I even would appreciate any info about them, any website, tutor or even what they are for. Here is a list below:

------------------------------------------------------------
25 To Life HOG, PSS
Beat Down : Fist of Revenge PSS, XAF
Call of Duty 2 PSV, COD, TM2
Crazy Frog Racer PC
Fahrenheit BIK, "BIGFILE.DAT"
Fifa World Cup Germany 2006 BIG
Getting Up PK2
Harry Potter BIG
Ice Age 2 : The Meltdown PSS, PAD, BIN, 000
Judge Dredd : Dredd vs Death MIC, ASR, PSS
King Kong BIK, "DATA.BF"
Matrix : Path of Neo WAD, SFD
Metal Gear Solid 3 : Subsistence DAT
Need For Speed : Most Wanted BIG
Smak Down : Here Comes The Pain PAC, AFS, SFD
The Godfather : The Game VIV
Tomb Raider : Legend PSS, "BIGFILE.DAT"
Total Overdose NAZ, PS2
------------------------------------------------------------

I tried to be a tidy boy and make it look as neat as possible ;)

I don't think you can

Well why not? I've already been able to encode/decode PSS, ADX, AFS, SFD and BIK files. Maybe some other ppl can do more.

Try taking a look at this (http://filext.com/) site ;)

the filext site is a good idea, but it never helped, because these files can't be found as the site says.

BTW, are these files some common files? or are some only used for the specific game?

Try at www.alucard.cc forums they are great at cracking ps2 code.
