Getting Started
This software allows you to modify "The Legend of Zelda: A Link to the Past" (US or JP) ROMs.
This editor is built to be compatible with ZScream projects and is designed to be cross platform.
Please note that this project is currently a work in progress, and some features may not be fully implemented or may be subject to change.
General Tips
- Experiment flags determine whether certain features are enabled or not. To change your flags, go to
File>Options>Experiment Flagsor in the Settings tab. - Backup files are enabled by default. Each save will produce a timestamped copy of your ROM before you last saved. You can disable this feature in the settings.
Extending Functionality
In addition to the built-in features, this software provides a pure C library interface and a Python module that can be used for building extensions and custom sprites without assembly. In the editor these can be loaded under the Extensions menu.
This feature is still in development and is not yet fully documented.
