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

## Dataset Description
The Mario Maker 2 level comment dataset consists of 31.9 million level comments from Nintendo's online service totaling around 23GB 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 level comment 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_level_comments", streaming=True, split="train")
print(next(iter(ds)))

#OUTPUT:
{
 'data_id': 3000006,
 'comment_id': '20200430072710528979_302de3722145c7a2_2dc6c6',
 'type': 2,
 'pid': '3471680967096518562',
 'posted': 1561652887,
 'clear_required': 0,
 'text': '',
 'reaction_image_id': 10,
 'custom_image': [some binary data],
 'has_beaten': 0,
 'x': 557,
 'y': 64,
 'reaction_face': 0,
 'unk8': 0,
 'unk10': 0,
 'unk12': 0,
 'unk14': [some binary data],
 'unk17': 0
}
```
Comments can be one of three types: text, reaction image or custom image. `type` can be used with the enum below to identify different kinds of comments. Custom images are binary PNGs.

You can also download the full dataset. Note that this will download ~23GB:
```python
ds = load_dataset("TheGreatRambler/mm2_level_comments", split="train")
```

### 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
CommentType = {
	0: "Custom Image",
	1: "Text",
	2: "Reaction Image"
}

CommentReactionImage = {
	0: "Nice!",
	1: "Good stuff!",
	2: "So tough...",
	3: "EASY",
	4: "Seriously?!",
	5: "Wow!",
	6: "Cool idea!",
	7: "SPEEDRUN!",
	8: "How?!",
	9: "Be careful!",
	10: "So close!",
	11: "Beat it!"
}

CommentReactionFace = {
	0: "Normal",
	16: "Wink",
	1: "Happy",
	4: "Surprised",
	18: "Scared",
	3: "Confused"
}
```

## 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 comments from many different Mario Maker 2 players globally and as such their text could contain harmful language. Harmful depictions could also be present in the custom images.
