OFFZIP破解含ZLIB压缩的包文件[汉化工具]

很早就准备把这个工具发出来，一直没空，现在抽空把它发出来。
很多包文件为了游戏更快地读取，会使用ZLIB把游戏的数据压缩为一块一块的压缩数据块。比如CSI纽约等等。著名的街霸4的解包工具也是在这个工具的基础上开发出来的。
在这些压缩数据块的头部都有一些特定的标记，这个工具根据这些特定的标记，能把压缩数据块自动识别和解压缩出来。

使用方法如下
Usage: offzip.exe [options] <input> <output/dir> <offset>

Options:
 
-s      search for possible zip/gzip data in the input file, the scan starts
        from the specified offset and finishs when something is found
        the output field is ignored so you can use any name you want
-S      as above but continues the scan (just like -a but without extraction)
-a      unzip all the possible zip data found in the file. the output
        directory where are unzipped the files is identified by <output> 
        all the output filenames contain the offset where they have been found
-A      as above but without unzipping data, the output files will contain the  
        same original zipped data, just like a simple data dumper R/ 7G 
-1      related to -a/-A, generates one unique output file instead of many  
-m SIZE  lets you to decide the length of the zip block to check if it is a  
        valid zip data. default is 32. use a higher value to reduce the number  
        of false positive or a smaller one (eg 16) to see small zip data too
-z NUM  this option is needed to specify a windowBits value. If you don't find  
        zip data in a file (like a classical zip file) try to set it to -15  
        valid values go from -8 to -15 and from 8 to 15. Default is 15 
-q      quiet, all the verbose error messages will be suppressed  
-r      don't remove the invalid uncompressed files generated with -a and -A 
 
Note: offset is a decimal number or a hex number if you add a 0x before it  
      examples: 1234 or 0x4d2
