The release of the 3 test 'hacked' DLCs was a test of the technology, as well as the reaction of the community.

re: Hacked DLC item and future Nintendo items
I've picked item codes that are very unlikely to be used by Nintendo (unless they intentionally want to overlap).
In the ideal world, good hackers and Nintendo can live together and we all sing kumbaya and there won't be conflicting IDs.
But collisions may happen,
Each town has their own copy of DLC. They trade them but the first one that is installed wins. So two towns may have two different interpretation of DLC item codes. See below for getting rid of them.
Most scenarios are ok. The game compensates. Lets say you mixed up two hat types, then two people would view the town in different ways.
When they aren't compatible, you mix up a hat type and a tool type, the game also compensates.
Sometimes a hat is not drawn and you get a bald character. The "headless hat" photo on my website is another example of some things out of whack.
Things may look weird but I haven't seen it crash (but that's not a promise because you know some 'bad hacker' is going to try to make something damaging like the "seed" problem in AC:WW).----
re: get rid of DLC
Getting rid of DLC you don't want is a stickier issue. Normally DLC you don't use is ignored by the game. I don't think it's a problem today (since there are only 5 items with no overlaps). It will get messy when more people create DLC items unless we are careful.BTW: Getting rid of unwanted DLC is easy if you have WiiBrew. Non-WiiBrew users don't have a good answer at the current time. They can start their town over and immediately visit a town with the wanted DLC. Or they can install WiiBrew.
So bottom line, conflicting item codes are not the end of the world, but for a number of good reasons we should try to avoid them.[/quote]
