Sonic Adventure: 3 Open Source Clones Compared
sadx_decomp and Sonic Adventure DX are both unplayable, work-in-progress decompilation efforts targeting different releases — the Windows PC version and the GameCube version respectively — and sadx_decomp's development has stopped entirely (marked dead) while the GameCube decompilation is only halted. Sonic Adventure Toolset is a different kind of project altogether: an actively maintained modding and asset-extraction toolkit distributed as prebuilt Windows binaries, rather than an attempt to rebuild the game's source.
