Seems the new ridge racer game uses an ultra compression technique that when you remove the 360 padding the actual game size is 1gb. They must of used some sort of compression scheme because i cannot even recognize anything in the bigfiles.

Re: Ridge Racer Unbounded Compressed files.
could be zlib compression as offzip (http://aluigi.altervista.org/mytoolz/offzip.zip) seemed to find something

Re: Ridge Racer Unbounded Compressed files.
Doiesn't look like zlib.
I gues we will have to wait for the pc/ps3 version to find out if its the same compression. Man why does namco do that?

Re: Ridge Racer Unbounded Compressed files.
Could be zlib compression since the track editor crashes with zlib error (incorrect header check) in the PC version.

Re: Ridge Racer Unbounded Compressed files.
PC Version is using Zlib. Is the window bits value different?
Click the thanks button if I helped!

Re: Ridge Racer Unbounded Compressed files.
I tried to open it using zlib but had no success. Could you extract it C00L12345?

Re: Ridge Racer Unbounded Compressed files.
Yes that should be the archive type from Flatout: viewtopic.php?p=9533#p9533
So were you able to unpack it? Sorry for that noobish question, I really have a very limited knowledge about this stuff
I wouldn't know what to do with the stuff you posted :s

Re: Ridge Racer Unbounded Compressed files.
Well i was able to build a 1/2 module for Unpakke for that game.
So far i can successfully unpack "00__ridge_racer__" (full of XML's) and "02____update_____" (where the localization files are). The last "01___unbounded___" archive has something strange in the structure that i didn't figure yet but... stay tuned i guess...?
The "BFS1" format is key encrypted (custom encryption as much as i am familiar with cryptography...).
The structure is key encrypted also, with algo similar to the file one, but this time it's executed in 6 rounds.
The file names and file path of every entry is obfuscated a little and... hash table encrypted.
Finally, the file entries are simply ZIP-ed.
Those guys really don't want no one to pick with the game res...
Here's the file structure of "02____update_____" (just to prove my words):
(Sorry for the "АДДД" crap, but that how Windows tree.exe dump the table 
)

Re: Ridge Racer Unbounded Compressed files.
Awesome
Well I looked into the .exe with Ollydgb and it seems like the game includes a hell lot of source code (according to the filenames). Maybe thats why they don't want that file to openend so easily.
