Fantastic Dizzy Tools

About

Fantastic Dizzy is a game published by Codemasters in 1991, released for DOS among other platforms. Fantastic Dizzy Tools is a small set of Python scripts for extracting, repacking, and viewing assets from the DOS version of Fantastic Dizzy. It includes an asset unpacker and repacker for the game's DIZZY.NDX/DIZZY.RES data files, plus a sprite-set viewer and a stage/level viewer, along with notes on the game's data formats. The tools are released into the public domain.

Getting started

To extract game assets, run the unpacker script against the game's DIZZY.NDX and DIZZY.RES files, which creates individual chunk files in an output folder. A companion repacker script can rebuild those files for modifying the game, and separate viewer scripts let you browse sprite sets and stage layouts using the arrow and number keys.

Known issues & limitations

• graphics: Sprite colours may be incorrect because sprite sets can include sprites for multiple stages with different palettes.
• graphics: Some palette colours in stage viewer are displayed incorrectly; palette encoding for tiles is not fully understood.
• The tools have known display quirks: some sprite colors can appear incorrect because sprite sets share palettes across stages, and the tile palette encoding used for stages isn't fully understood.
