Legend of Zelda Map Generator

About this project

This tool can be used by players and hackers to generate maps of their favorite Zelda hacks when they are stuck or otherwise want to see full maps of the overworld and dungeons with all secrets revealed.

It can also be used by hackers to aid in locating specific Zelda screens, columns, or other data and explore other hacks. It is exploratory only and does not write any data.

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