SMM Data Store methods

Updates to https://github.com/Kinnay/NintendoClients/wiki/Data-Store-Protocol-(SMM)

#include "CommonTypes.bt"

struct Unknown_0x004a_request {
    uint32 id; //observed values: 0x82, 0x81, 0x80
};

struct Unknown_0x004a_response {
    uint32 size;
    qBuffer data[size] <optimize=false>;
};

I’ve written a few scripts that help with the initial analysis (for example, one that converts all bytes in the .text segments to code because IDA mistakenly marks it as data sometimes) and repetitive or annoying tasks. Other than that, I do almost everything manually.

I only used lost reavers to find out where the datastore methods are located. After that, I analyzed the methods by hand. I’ve seen these methods often enough that I can recognize them easily. I don’t even have a decompiler for PPC so I’m just looking at the plain assembly code 🙂

Ok, I updated the wiki. I also compared it against our packets again and it seems to exactly match the docs now.
