有个开源的软件 quickbms

解密4.5版本以及以下都可以。后面的版本解不了。关键是这个软件开源。

# Blade and Sword II 《刀剑2》
# Note: directory tree not handled, only last folder
# script for QuickBMS http://quickbms.aluigi.org

set KEY binary "\x54\xCC\x95\xB9\x4B\xA1\x9C\x25\x89\x08\x47\x64\x43\x15\x0A\x57"

idstring "spkm1.0\0"
get DUMMY long
get ALIGN long
getdstring HASH 16
get INFO_OFF long
get DUMMY_OFF long

# useless data

log MEMORY_FILE3 0 SIZE MEMORY_FILE
get NAMES_SIZE long MEMORY_FILE3

log MEMORY_FILE4 TMP NAMES_SIZE MEMORY_FILE3
goto NAMES_SIZE MEMORY_FILE3 SEEK_CUR

set PATH string ""

   break

math NAME_OFF >> 2
math FLAGS & 3

if FLAGS == 0
   goto -3 MEMORY_FILE3 SEEK_CUR

   goto NAME_OFF MEMORY_FILE4
   get NAME string MEMORY_FILE4

   if FLAGS & 2
         set PATH string NAME
   elif FLAGS & 1
         get OFFSET long MEMORY_FILE3
         math OFFSET * ALIGN

         goto OFFSET
         callfunction DUMP 1
         string NAME p "%s/%s" PATH NAME
         log NAME 0 SIZE MEMORY_FILE
   endif
endif
next

startfunction DUMP

get DUMMY byte
get DUMMY long
get DUMMY long
get DUMMY long
padding 16
get SIZE long
get ZSIZE long
get ENTRY_SIZE long
get NEW_OFFSET long
getdstring HASH 16
savepos OFFSET
math ENTRY_SIZE * ALIGN
math NEW_OFFSET * ALIGN

# AES on the aligned size and XOR on the rest
math TMP_ZSIZE = ZSIZE
log MEMORY_FILE2 0 0
append
if NEW_OFFSET != 0
   math TMP = ENTRY_SIZE
   math TMP - OFFSET
   math TMP + ENTRY_OFF
   encryption aes KEY "" 0 16
   log MEMORY_FILE2 OFFSET TMP
   math OFFSET = NEW_OFFSET
   math TMP_ZSIZE - TMP
endif
math TMP = TMP_ZSIZE
math TMP y 16
encryption aes KEY "" 0 16
log MEMORY_FILE2 OFFSET TMP
math OFFSET + TMP
xmath TMP "TMP_ZSIZE - TMP"
encryption xor KEY "" 0 16
log MEMORY_FILE2 OFFSET TMP
encryption "" ""
append

if SIZE == ZSIZE
   log MEMORY_FILE 0 ZSIZE MEMORY_FILE2
else
   clog MEMORY_FILE 0 ZSIZE SIZE MEMORY_FILE2
endif

math ENTRY_OFF + ENTRY_SIZE
endfunction

更神奇的是这个软件只需要配置脚本弹解上万个软件的资源包

写脚本是门槛啊。。

解包后只有贴图音乐，怎么得到模型呢？

解包出来后最外层的目录没了，咋整呢:
