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。 ) H1 x; d8 K! s; Y

! Z; T- U+ O- X% A6 u* Zobviously 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.
( k9 x! g e4 K. }+ X% s7 Z+ dthen the input BMS script no longer needs the semicolon ';' and the file number which are now optional.

; e9 P/ [$ W3 A. E' uif 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:
