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

## Dataset Description
The Mario Maker 2 ninji levels dataset consists of 21 ninji levels from Nintendo's online service and aids `TheGreatRambler/mm2_ninji`. 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
You can load and iterate through the dataset with the following code:

```python
from datasets import load_dataset

ds = load_dataset("TheGreatRambler/mm2_ninji_level", split="train")
print(next(iter(ds)))

#OUTPUT:
{
 'data_id': 12171034,
 'name': 'Rolling Snowballs',
 'description': 'Make your way through the snowfields, and keep an eye\nout for Spikes and Snow Pokeys! Stomping on Snow Pokeys\nwill turn them into small snowballs, which you can pick up\nand throw. Play this course as many times as you want,\nand see if you can find the fastest way to the finish!',
 'uploaded': 1575532800,
 'ended': 1576137600,
 'gamestyle': 3,
 'theme': 6,
 'medal_time': 26800,
 'clear_condition': 0,
 'clear_condition_magnitude': 0,
 'unk3_0': 1309513,
 'unk3_1': 62629737,
 'unk3_2': 4355893,
 'unk5': 1,
 'unk6': 0,
 'unk9': 0,
 'level_data': [some binary data]
}
```
Each row is a ninji level denoted by `data_id`. `TheGreatRambler/mm2_ninji` refers to these levels.

## 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

As these 21 levels were made and vetted by Nintendo the dataset contains no harmful language or depictions.
