Hi, I am pretty familiar with the file format for the pro evo series but i have come across some files that refuse to unzip

Code:

struct ZlibWESYS
{
   char magic[8]; // "\x00\x10\x01WESYS"
   uint32_t cmprSize;
   uint32_t uncmprSize;
   uint8_t wesys[cmprSize]; // Uncompress with Zlib
}

The general structure is as stated above but this file has a different magic[8]

Code:

"\xFF\x10\x01WESYS"

Here is a sample

Please move this to game archives

There's like 3 different ways to decompress zip files (zlib,deflat,gzip). Raw zip formats don't have checks.
I think quickBMS can detect them all.

Try this tool:
