I will put up the known issues of the Hacked DLC.

1. Question: Can these HDLC ruin my game?
Answer: No. HDLC are like DLC from Nintendo, just made from someone else. There may be some “side effects” but you game will be safe.
2. Question: What are these “side effects?”
Answer: There are 3 “side effects” that can occur due to HDLC. None of them are fatal in any, way, shape, or form. They are more of just what happens than any thing. In fact, side effects may be a misleading term, but I cannot think of another phrase for it. Rest assured, your game will NOT be bricked.
3. Question Statement: Side Effect 1: Spot Taken
Answer: The first side affect is the very, very unlikely to happen. If a HDLC takes up the spot of a regular DLC, or another HDLC, then those new items will not exist to the player. Let’s take a scenario. Say player1 has the ShinyBluePikmin in slot $CA00. Now say player2 has an InsertLameItem in slot $CA00 and goes to player1’s town. InsertLameItem is furniture while the ShinyBluePikmin is a hat. If player2 drops his InsertLameItem and player 1 picks it up, player1 sees it as a ShinyBluePikmin. Everything that is in slot $CA00 is a ShinyBluePikmin to player1. The same is true for player2. Every item that uses slot $CA00 is an InsertLameItem. The game compensates very nicely. So at worst, if Nintendo creates a DLC that uses the same slot as one of the HDLC, then a player will only get whichever item that player got first. This is VERY unlikely as there are literally THOUSANDS of slots that DLC can be placed in.
4. Question Statement: Side Effect 2: I Can’t See
Answer: The second side affect has to deal with the first side affect. Again, it will NOT mess up your game. If two players have two different items located in the same slot, each player sees something different. Let’s take the above example. We have player2 visiting player1’s town. Say player1 decides to put on his ShinyBluePikmin. Now to player2, that is an InsertLameItem, not a hat of any kind. Player1 sees himself with his ShinyBluePikmin hat on. However, player2 does not see the hat. Player2 will recognize that player1 is wearing some hat, but the hat will not be there. So essentially, Player2 sees a bold Player1. Again, the game compensates very nicely and it does NOT mess up one’s game.</div>
Sadly, Side Effect 2 cannot be avoided. You might have it, I might have it too.
