paq解包脚本如何写

分析了半天还是没分析出解压脚本

解压不出东西

收到，你先说说你分析出了点什么。
是如何分析出的，根据是什么。

可以先手工试试看。offzip.

解到tga格式文件就出错了。。格式不一样的。。

Offset file unzipper 0.3.3 (offzip) .image.
a very useful tool to unpack the zip (zlib/gzip/deflate) data contained in any type of file included raw files, packets, zip archives, executables and anything else.
0 \0 B5 e& \7 g7 S7 V- Q+ I* Ait's needed only to specify the offset where the zip data starts or using the useful -S search options able to find any possible zip block contained in the provided file.
naturally there are also other options for extracting all the zip blocks which have been found or dumping them as in their original compressed form.
it's also possible to choose a windowBits value for scanning both the zlib (RFC1950) and deflate (RFC1951) blocks (for example -z -15 for common zip files and so on).

也研究研究下007提供的offzip
