Writing a libemu/Unicorn Compatability Layer

In this post we are going to take a quick look at what it takes to write a libemu compatibility layer for the Unicorn engine. In the course of this work, we will also import the libemu Win32 environment to run under Unicorn. For a bit of background, libemu is a lightweight x86 emulator written in...
