In 2021, a secret display mode for the PlayStation 2 version of the game was discovered that can be unlocked by starting a new game with the profile name "PSONE". Doing this will cause the game to lower the standard output from 480p to 240p and disable texture filtering, making it more closely resemble a PlayStation game. This mode is referred to as "Christian Slater mode" in the source code and was added to the game by programmer François Queinnec, but he did not remember why it was called that and chalked it up to being an in-joke with a forgotten meaning.
