paq解包脚本如何写

byp100

分析了半天还是没分析出解压脚本
苏洋的解包动画也看不到。。。。007能分析指导一下吗？

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.
& J/ t" w$ ~0 l1 n0 ma 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.
9 p* `- g$ D3 i1 N8 `' rit'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).

不错，确实能解压一部分，我参考参考写法
