最近老外开发了一个很不错的通用命令行解包器，以后制作解包器只要简单的写几句脚本就行了。 % W0 m+ t- e/ y) n: H
现在老外还在不断完善之中，有兴趣的朋友来测试一下吧。 # s4 A; p7 K* M# Q

0 v* s) O) e) F. jI have made it compatible with the BMS scripting language so people don't need to learn 1000 languages and then it's a good language.
+ r3 f6 d5 g! n z- q* Q' Wobviously the BMS support has been enhanced so it's possible to use XOR, rot13, zlib/deflate, lzo, lzss plus various new operator in the "math" command (and, or, xor, complement, not, shift and modulus) and some other things like choosing the desired endianness.
' E9 I8 G0 Z+ C2 bthen the input BMS script no longer needs the semicolon ';' and the file number which are now optional.

note that the BMS guide available on http://wiki.xentax.com/index.php/BMS doesn't report some additional fields which instead already exists like the GetCT, ComType and ReverseLong or some internals variables like EXTRCNT so I have tried to find and add also these ones. 2 ~5 y& U, g. |1 x1 F; X

about the new commands, the following is an example of BMS script for the game Outcry (you can call it outcry.bms or outcry.txt or as you want):

if you know the size of the structure or where is located the particular value you are searching (for example some file formats have a 32bit number in the last 4 bytes which has the offset where are located the other file structures) you could use something like the following: ) E8 B0 n. M( d/ y0 U
) s; D, f( L6 r5 W. r$ B0 N; V9 Z2 N$ NCode:get OFFSET asize 9 C1 \+ r1 [" ` ]! e

k$ E- B2 G+ a: sgoto OFFSET
; N+ F: F7 W) d/ H+ V6 Kget OFFSET long 6 e5 d; V8 |6 q1 H( x
goto OFFSET % m# Q% m+ A' c
..."asize" is not available in the BMS guide but is supported by both multiex and my tool, it contains the total size of the file.
: J) p$ y$ h4 _' U+ R- r* Manyway tell me a file format which has the file name table at the end, it's good to make various exercises for testing the BMS language and where is possible to enhance it. ! B" ~; C4 f6 U
