VRC PRO - .VRC and .VRH

Post by ReVolt » Thu Mar 04, 2021 9:49 pm

Does anybody know how to open these? I would like to dig into this game's files, but they're encrypted in these VRC and VRH files.
Samples:
VRC:

VRH:

Thanks. :)

I found a VRC quickbms! Did not expect that since how dead the community of this game is.
But the sad part is, and there's always a sad part, is that "the input file doesn't seem encrypted". ??? :?:

Well, VRC, VRH, CAR files is encrypted by AES-256-CBC. Output data is a passwored ZIP. So here script for convert this files to normal ZIP

Password for ZIP's -> d17856f1ce

Code: Select all

# Virtual RC Pro (VRC / VRH / CAR) to ZIP Converter
# script for QuickBMS http://aluigi.org/papers.htm#quickbms

get SIZE asize
goto 9
savepos OFFSET
math SIZE -= 9

encryption aes_256_cbc "\xB6\x8E\x4D\x98\xBC\xDB\x62\x1B\x0E\x98\x52\x05\xD0\x07\x5C\xF2\xAA\x53\xC4\x88\xAE\x41\xFD\xC7\xFE\x1D\xA7\xD6\xC7\x6E\xA1\x7F"
log MEMORY_FILE OFFSET SIZE
encryption "" ""

putvarchr MEMORY_FILE 0 0x4034B50 long
putvarchr MEMORY_FILE 4 0x90014 long
putvarchr MEMORY_FILE 8 0x8 long
putvarchr MEMORY_FILE 12 0 long
putvarchr MEMORY_FILE 16 0 long
putvarchr MEMORY_FILE 20 0 short

get NAME basename
string NAME += ".zip"

log NAME 0 SIZE MEMORY_FILE
Have fun :keke:
