# 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!",

}
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.
