Abstract
A data protection portion includes the file alteration checking portion. One aspect of the file alteration checking portion relates to a media including game content and a data protection portion. In one version, the data protection portion protects the game content from modification by determining whether the game content has been modified. If the game content has been modified, then the installation of the game content within the apparatus fails.
