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。 P) ^+ a ]5 s( W' _
现在老外还在不断完善之中，有兴趣的朋友来测试一下吧。

; }, K/ x, }' x9 l8 F. C9 sI 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.
0 _2 H5 f7 `7 l# gobviously 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. ( M, U' G0 Y: `0 [" j
then the input BMS script no longer needs the semicolon ';' and the file number which are now optional. / L/ d. p' g- k& {
! X. v9 K$ ]) r4 ]# W$ D' u
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.

: a2 y; W4 G% j8 ?7 P4 b- r7 Gif 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:
0 E3 b0 Q3 o8 V% |/ P
+ Z- e% p2 K7 o4 @5 H1 o; k" ICode:get OFFSET asize 3 [- D3 z( q: m2 _" w" {$ F
math OFFSET -= 4 7 F2 V6 `1 ^$ g. N* ?
goto OFFSET : h2 N0 ]+ [" g( f; y
get OFFSET long ) F! C' T2 [: Z8 e
goto OFFSET
& a+ l z9 S @7 b/ n..."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. : \6 O4 L' Z8 M$ y& [
anyway 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. , p! z6 m" |5 n! W
