VPP version 2

[D8174]

Not sure if you care about VPP 2 as it's not used in any of the games listed here (I only know of Summoner 2) but I thought it can't hurt to open an issue.

I modified some VPP 3 deserialize code and it kind of works except when trying to write, there's Unhandled Exception: System.IO.EndOfStreamException: Attempted to read past the end of the stream.

Wondering if you could give me any pointers?

Some info: I've tried writing my own program in C++ to extract and inflate the files in the VPP by incrementing the stream position by the uncompressed file size for each file and running zlib uncompress on those bytes but I get zlib errors.
