The Original Xbox has a small library of titles that contain hidden and unlockable games. In most instances you need to complete the main game to in order to play the unlockable game.
In this video with a modded xbox, and a copy of a custom dashboard, like Unleash X, i show games that i have that contain unlockable or hidden games and how to play them without needing to unlock them in the main game.
