Leftovers from previous versions

Tutorial menu


Previous releases of Sonic Adventure 2 had a Tutorial presented by Omochao in the Extras sub-menu. The 2012 version replaced this, however the original Omochao version (as well as the option for it) are still in the game and is identical to the GameCube version.

GameCube memory card

In the Steam version's files, Data_DLL.dll's cardObj export contains a list of four models of GameCube memory cards in a box with indicators for Slot A and Slot B in English and Japanese above them. Additionally, textures for the GameCube model that appears in the back of the GameCube version's save file select screen can be found in fileSelect.prs, fileSelect_e.prs, fileSelect.pak, and fileSelect_e.pak.
