+The N64 releases of Ocarina of Time will always address a maximum of 4 MiBs of ram by default, regardless of what ram pack is installed. N64 versions have an extra interesting wrinkle to them since the game was planned to be expanded via the Disk Drive. Installing the DD changes how ram is utilized since the extra code to interface with the DD system pushes OoT past its tight memory requirements and mandates the 8 MiB expansion.
