Nitro Hax is a cheat tool for official games running on the Nintendo DS. It supports any Action Replay DS code type with a few important additions.

Release notes:

New version 0.91 out. Not many changes this time, but it outputs debugging codes when loading the game. If it fails to load properly, the coloured squares will help figure out why.
