Debug Mode

A PlayStation 2 TOOL (DTL-T10000H) development console used exclusively by game studios to develop games for the PlayStation 2.

Debug mode, often mistaken for Cheat Mode, is the mode in which the game boots with in-game debugging tools enabled. Debugging tools can be accessed in Jak and Daxter: The Precursor Legacy, Jak II, Jak 3, and Jak X: Combat Racing.

These tools were only ever meant to be used by the developers at Naughty Dog to help diagnose bugs during the development cycle of the Jak and Daxter games.
