Cosmic break [.kar] files

Post by Sadiosys » Wed Nov 23, 2011 2:59 pm

Hello Xentax!
Cosmic break - japanese MMOFPS(massive multiplayer online first person shooter).
All game resources like textures, sounds and maybe main game executable are packed inside of .kar archives with some algorithm.
http://rghost.ru/32042611
http://rghost.ru/32042681
stage.kar - maps(maybe some images inside)
sample01.nsd -...
sample02.nsd -...
sample03.nsd - these files are maps created with ingame map editor so they arent inside .kar archive
CosmicBreak.exe - launcher that starts game and updates it; launcher downloads udates in form of small udpate_0911.kar files and later merges them with existing game archives.
cb.kar - was inside of folder Cosmicbreak/programs/ and it seems to be main game exe or something like that
setting.kar - was near cb.kar
cosmic.exe - this was near cb.kar; now some info i got. Game can be started via launcher or via cosmic.exe with parameter "launch". When cosmic.exe started it accesses different dlls, java VM(game built using some java technology and has Cosmicbreak/jre folder), and then cb.kar. After this game accesses different archives with images/sounds/etc and game window appears.
http://rghost.ru/31488321 - images.kar - images, and I think that there might be .png
Thats game client if it helps(500mb only):
http://download.getamped.com/CosmicBreakSetup_eng.exe

I need to extract game resources like models, sounds, images. Packing it back will be wonderful too but not must have. Too bad I Im not knowledgeable enough to understand how game decrypts resources.
UPLOADED FILES AGAIN.

Because files inside encrypted. For decrypt need password. Ask to toptaran pwd.
