ScePaf

Much of this page is wrong because much of the PAF is written in C++.

But it works as a "function".

Module

ScePaf is a C++ runtime.

Quick note on reversing. This module has many vtables that point to exported functions.

It would be great to start from marking which function belongs to which vtable.

This way we can restore initial class structure.
