Editroid is a Metroid level editor that can edit all level data. Version 2 shows as many game screens as can fit on your monitor and allows you to browse the game world with a mini-map. There is also a new feature to expand a ROM, increasing the amount of space available for level data.

• Expand ROMs to create more space for level data.

• Edit screens, “structures” used to build screens, and combos that structures are built from.
• Add/Delete screens and structures. This allows you to increase the number of predefined rooms and increase the variety in the rooms.
• Complete item editing, including which items (and red doors) are tracked by the password.
• Password data generator.
• Edit all palettes
• Improved physics view
