Changes

| style="text-align: center;"|All ports have updated player models, except Big and Gamma. GameCube version have additional missions and Game Gear games unlockable as a bonus. The bonus missions are sold as DLC on the PS3 and 360. PC version is the Directors cut. Note, however, that the ports, usually released as "Sonic Adventure DX: Director's Cut", are based on the original, less polished Japanese Dreamcast release, and are thus glitchier than the international (USA/PAL) Dreamcast releases, in addition to having new glitches of their own. A mod is available to fix these glitches for the PC edition.
