This utility was created during the development of The Legend of Zelda: A New Light to explore the column combos that are used to build screens. There’s very little info on this aspect of the game and no existing tools to work with it. The utility eventually progressed into a full map generator.

The tool can be used by hackers to aid in modifying Zelda columns and screens or explore other hacks. It is exploratory only and does not write any data.

It can also be used by players to generate a map of their favorite Zelda hack when they are stuck or otherwise want to see a full map of the game.

It is written in Javascript and HTML so it’s easily hackable.

The following maps are included in the package:

• Zelda A New Light
• Zelda Ganon’s Curse
• Zelda Hyrule’s Doom
• Zelda Link’s Shadow
• Zelda Outlands
• Zelda Awakening of Onyx
• Zelda Perils of Darkness
• Zelda Trial of Courage
• Zelda Triforce Power
• Zelda Wrath of Ganon

General Features:

• Read ROM data to generate an accurate map
• Provide APIs to explore and render combo data and screens
