Reverse engineering

Many attempts have been made throughout history to study the internals of this client. However, these usually aren't shared with the public.

A project of Thunderbrew, Binana, aims to provide machine-readable reverse-engineering information for the entire 3.3.5a binary in a single repository. By contributing to Binana, we can collaborate and build upon each other's work.

Compiler

For Windows, the client was known to be compiled using the Microsoft Visual C++ Compiler (VS2005, build 50727).

For the Mac OS X port, the XCode version of GCC was used.
