Editors

Editors Reference

FEBuilderGBA provides specialized editors for every aspect of the Fire Emblem GBA games.

Some FE8 editors (FE8 Spell Menu Extends, the Skill editors, Item Effectiveness (SkillSystems Rework)) are Skill‑System‑gated and only show data once a community Skill System is installed. See Skill Systems (FE8) for the recommended FE8U/FE8J sources and how to install them.

Working from a decompilation source tree? In Decomp Project Mode many of these editors (items, units/characters, classes, map/chapter, supports) write their changes back to the owning C struct / JSON source element instead of mutating the ROM. Run --decomp-audit for the authoritative per-editor coverage matrix.
