Mario Maker 2 ninji levels

Part of the Mario Maker 2 Dataset Collection

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 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:

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. level_data is the same format used in TheGreatRambler/mm2_level and the provided Kaitai struct file and level.py can be used to decode it:

from datasets import load_dataset
from kaitaistruct import KaitaiStream
from io import BytesIO
from level import Level
import zlib

ds = load_dataset("TheGreatRambler/mm2_ninji_level", split="train")
level_data = next(iter(ds))["level_data"]
level = Level(KaitaiStream(BytesIO(zlib.decompress(level_data))))

# NOTE level.overworld.objects is a fixed size (limitation of Kaitai struct)
# must iterate by object_count or null objects will be included
for i in range(level.overworld.object_count):
    obj = level.overworld.objects[i]
    print("X: %d Y: %d ID: %s" % (obj.x, obj.y, obj.id))

#OUTPUT:
X: 1200 Y: 400 ID: ObjId.block
X: 1360 Y: 400 ID: ObjId.block
X: 1360 Y: 240 ID: ObjId.block

Dataset Creation

The dataset was created over a little more than a month in Febuary 2022 using the self hosted 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.
