European Puzzle Swappers- Obtain the event puzzle "Mario & Happy" with this specific Spotpass dump

Hello!

There is a Spotpass dump that includes Mario & Happy (and all other puzzles) here, on gbatemp:
https://gbatemp.net/download/streetpass-mii-plaza-eur-most-puzzles.36038/

Some information:

• Above everything else, make sure to back-up data as usual! I'm not the dumper, nor am I responsible for anything happening to your data.
• This will definitely work on European 3DSes- I imagine it won't on others. I tested it on my Japanese 3DS and it reported the data as corrupted.
• This puzzle is not in the archive.org Spotpass set.
• I have tested this. If you've already used the pinned archive.org Spotpass data, there is no harm in overwriting it with this one. Your puzzle pieces will be exactly as they are, as the save file has not been touched. I talked with one person who, for some reason, couldn't see the Picross puzzle after updating their data, but it ended up as a visual glitch that was fixed by a reset.
• This puzzle works like the other Spotpass ones- you cannot obtain Mario & Happy pieces without using the Spotpass data, nor can you add it just by using a save file editor. I tried Streetpassing two of my 3DSes, one with the data and one without, and the puzzle did not appear. I also tried adding the pieces with a save editor.
• When you install this data, it will give you a piece of the puzzle immediately, meaning you don't then have to also edit your save file to give you a piece, or Streetpass someone that already has a piece. You can then either Streetpass others for the rest or use Play Coins (there are no pink pieces on it! 24 blues).
• With this, a European 3DS with every possible puzzle will have 57 puzzles, totalling at 1736 maximum pieces- without it, they'll have 56 puzzles with 1712 maximum pieces. (if you're using the fandom list to count, it's wrong, as Brain Age and Chibi-Robo! are both European puzzles too (with different names) and they are not marked as such).

I'm very excited to have been able to find this- massive thank you to the original uploader, Ryccardo, for the original upload. I've left him a review on gbatemp specifically letting him know how rare this is.

What's next- as far as I can tell, there are no event puzzles for USA Puzzle Swap, and Mario & Happy is the only European one. Japan has two different event ones- マックでDS ビッグマック , a McDonalds Big Mac promo puzzle, and ANAでDS , an All Nippon Airways promo puzzle. These were only available for 2-3 months in 2012. I have done some searching and cannot find any uploads of either. For us to find them, we would either need to find an existing dump, or find someone who has these, and kindly ask them to dump their Spotpass data for everyone else.

I have not used Play Coins for any more pieces of this puzzle and I very much look forward to seeing more people with this puzzle over NetPass. Happy StreetPassing!
