	# Mario Maker 2 super worlds
	Part of the [Mario Maker 2 Dataset Collection](https://tgrcode.com/posts/mario_maker_2_datasets)

	## Dataset Description
	The Mario Maker 2 super worlds dataset consists of 289 thousand super worlds from Nintendo's online service totaling around 13.5GB of data. The dataset was created using the self-hosted [Mario Maker 2 api](https://tgrcode.com/posts/mario_maker_2_api) over the course of 1 month in February 2022.

	### How to use it
	The Mario Maker 2 super worlds dataset is a very large dataset so for most use cases it is recommended to make use of the streaming API of `datasets`. You can load and iterate through the dataset with the following code:

	```python
	from datasets import load_dataset

	ds = load_dataset("TheGreatRambler/mm2_world", streaming=True, split="train")
	print(next(iter(ds)))

	#OUTPUT:
	{
	'pid': '14510618610706594411',
	'world_id': 'c96012bef256ba6b_20200513204805563301',
	'worlds': 1,
	'levels': 5,
	'planet_type': 0,
	'created': 1589420886,
	'unk1': [some binary data],
	'unk5': 3,
	'unk6': 1,
	'unk7': 1,
	'thumbnail': [some binary data]
	}
	```
	Each row is a unique super world denoted by the `world_id` created by the player denoted by the `pid`. Thumbnails are binary PNGs. `unk1` describes the super world itself, including the world map, but its format is unknown as of now.

	You can also download the full dataset. Note that this will download ~13.5GB:
	```python
	ds = load_dataset("TheGreatRambler/mm2_world", split="train")
	```

	## Data Structure

	### Data Instances

	```python
	{
	'pid': '14510618610706594411',
	'world_id': 'c96012bef256ba6b_20200513204805563301',
	'worlds': 1,
	'levels': 5,
	'planet_type': 0,
	'created': 1589420886,
	'unk1': [some binary data],
	'unk5': 3,
	'unk6': 1,
	'unk7': 1,
	'thumbnail': [some binary data]
	}
	```

	### Data Fields

	\|Field\|Type\|Description\|
	\|---\|---\|---\|
	\|pid\|string\|The player ID of the user who created this super world\|
	\|world_id\|string\|World ID\|
	\|worlds\|int\|Number of worlds\|
	\|levels\|int\|Number of levels\|
	\|planet_type\|int\|Planet type, enum below\|
	\|created\|int\|UTC timestamp of when this super world was created\|
	\|unk1\|bytes\|Unknown\|
	\|unk5\|int\|Unknown\|
	\|unk6\|int\|Unknown\|
	\|unk7\|int\|Unknown\|
	\|thumbnail\|bytes\|The thumbnail, as a JPEG binary\|
	\|thumbnail_url\|string\|The old URL of this thumbnail\|
	\|thumbnail_size\|int\|The filesize of this thumbnail\|
	\|thumbnail_filename\|string\|The filename of this thumbnail\|

	### Data Splits

	The dataset only contains a train split.

	## Enums

	The dataset contains some enum integer fields. This can be used to convert back to their string equivalents:

	```python
	SuperWorldPlanetType = {
	0: "Earth",
	1: "Moon",
	2: "Sand",
	3: "Green",
	4: "Ice",
	5: "Ringed",
	6: "Red",
	7: "Spiral"
	}
	```

	<!-- TODO create detailed statistics -->

	## Dataset Creation

	The dataset was created over a little more than a month in Febuary 2022 using the self hosted [Mario Maker 2 api](https://tgrcode.com/posts/mario_maker_2_api). As requests made to Nintendo's servers require authentication the process had to be done with upmost care and limiting download speed as to not overload the API and risk a ban. There are no intentions to create an updated release of this dataset.

	## Considerations for Using the Data

	The dataset consists of super worlds from many different Mario Maker 2 players globally and as such harmful depictions could be present in their super world thumbnails.
