These codes enable you to access interiors such as Wu Zi Mu’s betting store, that you can’t normally access during gameplay. Most of them are only used in cutscenes, during one particular mission, and some weren’t used in the game at all. To access these interiors, select the necessary code, enter the “via” location and you are automatically taken to the hidden interior. Once inside, the only way to get back out is to kill CJ or reset your PS2. Have fun!
