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。

; T2 D' U' Q1 gI 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. " y1 M* [% y; M+ R" ~
obviously 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.

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. ! x; C1 P" C; a2 I4 ^9 o" d* X- g" N L" K1 g

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: 3 G8 O6 C) O4 c- T0 c
% U7 y, z5 e* E9 h' I
Code:get OFFSET asize
1 P! ~! T$ h0 p4 ~0 V6 _0 O( hmath OFFSET -= 4

: \7 j8 a( v6 V/ |get OFFSET long & }- ? u/ b3 V, Q( d$ A; @
goto OFFSET * |. R% t4 X2 i2 d9 {
..."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.
: O1 Z1 G7 V) Eanyway 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.
