sadx_decomp

About

Sonic Adventure is a 1998 Dreamcast platform game by Sonic Team, the first main Sonic game with 3D gameplay, in which six playable characters each pursue their own quest to collect the Chaos Emeralds and stop the ancient evil Chaos. sadx-decomp is an archived, unplayable project aiming to recreate the Windows PC executable and DLLs of Sonic Adventure DX: Director's Cut in C and C++, letting the game's code and data be edited and recompiled rather than patched directly in the original binaries.

Additional notes

Scope

Work began with the DLL containing character model and animation data, with the main executable planned as a later, harder goal since it holds most of the game's code.
