A product that is used to glitch, cheat, hack or mod a video game. Action Replays are available for all modern game systems and if you still have one that works, older gen systems. Example of codes are infinite health, all items unlocked/infinite items, or max cash. When using Action Replays, especially when inputting your own codes, one must be careful because one can corrupt the data of your game to the point where all the data is deleted, or the game stops working. One common problem with Action Replays, more common with Action Replay DS users, is suddenly and spontaneously it will stop working, or all the data on the Action Replay will be deleted, if not both.
I see your stuck in MGS. Need to borrow my Action Replay?
