# Sonic Adventure DX: an early matching decompilation of the 2014 Steam release

> Sonic Adventure DX is being reconstructed from its 2014 Steam executable as C and C++ source that matches retail machine code function by function. The project uses the identified Visual C++ 2010 SP1 compiler, game-specific function and code-generation maps, and reccmp scores to compare rebuilt functions. The author reports an early stage with six exact function matches.
