Whoa... Hey Nintendo, apperently you need to fix something...
Well good luck, hopefully you get your files back.

Ok after hard reset, went into mario game and coin rush, shop. I bought the packs successfully for £6

Now playing them

Congrats!

Got the notification now ^^

That Nerve-Wreck pack is tricky.
It's well past four in the morning and I'm struggling to keep my eyes open and as a result I couldn't get to the end of the first stage.
Might try again a bit later when I can actually see what I'm doing properly.

I have to say it only took like 5 seconds to download all the DLC?? That tells me that all that DLC content that I payed 6quid for was already on the cartridge. I just payed them to unlocked it.

I don't agree with that kind of DLC at all. I bought the game and so I should get 100% of the content without having to pay extra for them to unlock more content on the cartridge.

It wasn't on there. It's just all you downloaded was code. You're not downloading any new game models or anything. NSMB2 is a pretty small game because Nintendo is efficient with compression and things like that to save on memory.

You downloaded new course designs, which in itself doesn't take much space. It wasn't already on the game.

I need proof. I downloaded all three dlc packs in less than 5 seconds. They can't be that small in size no way. I'm on virgin ISP so my speeds aren't great either

Assuming that a quick download speed means it's already on-cartridge is silly. Let's put this in perspective: The original Super Mario Bros takes about (usually less than, depending) a second to download. I think it's around 45 KB. That's the entire game, its music, sound effects, graphics, and 32 levels.

2D level files are either extremely small or a programmer at Nintendo is doing something wrong. This shouldn't surprise anyone.

What proof do you need? Why would you re-download objects in a game? All code is basically, is just text. You download instructions for the new levels. The game reads it and uses the objects already in the game.

These level designs weren't even created when NSMB2 came out.

In super basic terms, the level design could be stored extremely efficiently as pure numerical data (it won't be stored like this, because there are even more efficient ways, but go with this for now). Let's say (in a very basic system) you represent a block (ie, any ingame object) by two digits for the type of block and 4 digits for the grid position on-screen (2 for X, 2 for Y).
Let's say that a pipe is block 00, and we're placing it at grid tile (10, 20), so it appears at the start of the level. The data would simply be 001020. The game can read that and say "ok, 00 is a pipe, 10 is the X position and 20 is the Y position"
All of the graphics and sounds are already in the game, all the game has to do is download a big chunk of numbers. And numerical data is tiny. To demonstrate, I just created a file on my laptop with 150,000 numbers in it, which would support 25,000 blocks in our level builder. It's 130kb, uncompressed. Which would take less than a tenth of a second to download. I highly doubt that Nintendo's level packs are in uncompressed format, either. Levels can be stored in a tiny amount of data.

@ Bassmonsta

imagine if Luigis mansion2: dark moon would be DLC in new super mario bros2.Actually that would be magical. Even if LM2 was already on the cart of NSMB2. Actually a reason to buy it

Hmm, which packs to get.

I'm leaning towards the easy gold rush one and the difficult whack whatever its called one.

Nintendo fans not liking DLC, what a surprise. I agree with both perspectives, in that Nintendo games can stand on their own, but I already beat it and will gladly welcome more content.

Yeah, I downloaded all the Ambassodor NES games in a couple minutes.

Not gonna download it unless there are new bosses. . FE is more deserving of my cash.

Oh my god the DLC looks amazing! I can't wait to try the nerve-wrack pack! I thought it was already released in North America so I was looking forward to it all day...

I understand now. Thanks for the explanation.

What in the heck are you even talking about?
