FF6Tools review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

FF6Tools is a browser-based editor for supported Final Fantasy ROMs on NES, SNES, and Game Boy Advance. It is aimed at people who want to modify game maps, battles, monsters, character and item data, attacks, or scripts rather than work with ROMs generally. The project is open source and free. The app runs locally in the browser: ROM files are opened and saved on the user's computer, not uploaded to a server, and users supply their own ROMs.

Its editing scope reaches beyond map changes. Map tools handle tile drawing and triggers; battle and monster tools include monster placement where supported. Additional editors cover ROM data and event or monster AI scripts. Tilemap editing includes flips, layer priority, and palette index where available. Graphics can be imported and exported in supported formats, but the project does not provide built-in graphics editing. That distinction matters for users looking for a full sprite or image editor: FF6Tools can work with graphics assets, but it is not a replacement for dedicated graphics software.

The fit depends on the exact game and ROM version, since supported versions are specified in the project documentation. Modified ROMs are saved in a ZIP download with a definition file and ROM map. This browser workflow suits solo editors who want a focused set of tools without installing a desktop editor, while the specific Final Fantasy coverage limits its appeal to users working on other games. Choose it for supported ROM editing across maps, battles, data, scripts, and tilemaps; look elsewhere if you need broad game coverage or built-in graphics creation.
