Hello,
I need help to extract the game 'GuJianOL' 's files.
Anyone knows how? Thank you all.

The format has something in common with the one used New Sword of Legends Online (new_sword_legends.bms).
The following script should be able to decompress all the files:

Code: Select all

comtype lzma
get SIZE longlong
get ZERO longlong
get CEN_SIZE longlong
xmath CHUNKS "SIZE / 0x10000"
if            SIZE % 0x10000
    math CHUNKS + 1
endif

savepos OFFSET
xmath OFFSET "OFFSET + (CHUNKS * 12)"

get NAME basename
log NAME 0 0
append
for x = 0 < CHUNKS
    get CHUNK_SIZE long
    get SOME_CRC long
    get CHUNK_ZSIZE long
    clog NAME OFFSET CHUNK_ZSIZE CHUNK_SIZE
    math OFFSET + CHUNK_ZSIZE
next x
