🎮 Felix the Cat (NES) - World 1 Gameplay Dataset (NitroGen / BizHawk)

📝 Dataset Description

This dataset contains gameplay data from the NES game "Felix the Cat" (specifically World 1), formatted for fine-tuning the NVIDIA NitroGen model. NitroGen is a unified vision-to-action model designed to play video games directly from raw frames.

The dataset consists of screenshots and controller inputs (gamepad actions) stored in a Parquet format. It serves as a resource for training or evaluating models on imitation learning tasks within the NES environment.

Game: Felix the Cat (NES)
Segment: World 1
Format: Parquet (train.parquet)
Generated with: NitroGen BizHawk Dataset Generator

🖼️ Gameplay Preview

📂 Dataset Structure

The dataset is provided as a single .parquet file: train.parquet.

🔢 Data Fields

The dataset contains the following fields, representing the state of a standardized game controller and the corresponding video frame. Since the source system is NES, many fields are unused.

Active Fields (NES Mapping):
- south: Mapped to A button.
- west: Mapped to B button.
- start: Mapped to Start button.
- back: Mapped to Select button.
- j_left: Mapped from D-Pad (Up/Down/Left/Right).
Inactive Fields (Always False/Zero):
- east, north (Unused)
- left_shoulder, right_shoulder, left_trigger, right_trigger (Unused)
- guide, left_thumb, right_thumb (Unused)
- dpad_up, dpad_down, dpad_left, dpad_right (Unused)
- j_right (Analog stick, always [0.0, 0.0])
Image Field:
- image: A 256x256 RGB image of the game frame.

🛠️ Dataset Creation

This dataset was generated using the NitroGen BizHawk Dataset Generator.

📥 Data Collection Process

Emulation: Gameplay was recorded using the BizHawk Emulator (version 2.9+ recommended).
Export: A Lua script (export_dataset.lua) ran inside the emulator to capture frame-by-frame screenshots and controller inputs from a .bk2 movie file.
Processing: A Python script (convert_dataset.py) processed the raw exported frames and CSV data, resizing images (typically 256x256 via crop for NES) and embedding them into the final Parquet file.
