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 ~20GB: ```python ds = load_dataset("TheGreatRambler/mm2_level_comments", split="train") ``` ## Data Structure ### Data Instances ```python { '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 } ``` ### Data Fields |Field|Type|Description| |---|---|---| |data_id|int|The data ID of the level this comment appears on| |comment_id|string|Comment ID| |type|int|Type of comment, enum below| |pid|string|Player ID of the comment creator| |posted|int|UTC timestamp of when this comment was created| |clear_required|bool|Whether this comment requires a clear to view| |text|string|If the comment type is text, the text of the comment| |reaction_image_id|int|If this comment is a reaction image, the id of the reaction image, enum below| |custom_image|bytes|If this comment is a custom drawing, the custom drawing as a PNG binary| |has_beaten|int|Whether the user had beaten the level when they created the comment| |x|int|The X position of the comment in game| |y|int|The Y position of the comment in game| |reaction_face|int|The reaction face of the mii of this user, enum below| |unk8|int|Unknown| |unk10|int|Unknown| |unk12|int|Unknown| |unk14|bytes|Unknown| |unk17|int|Unknown| ### 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" } ``` <!-- 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 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.
