I've been wanting to buy an Action Replay for a while now, and last night I finally did. It will be coming in the mail within the next few days and I can't wait. I really only bought for the fact that I can use the test levels that the developers used to test the game.

Note: I'm now playing both Twilight Princess and Wind Waker. So both have been making progress, but I'll do an update about them seperatly later.
