Fire Emblem Awakening has had a couple of save editors over the years. I recently made a new save editor for this game, with many more features and quality of life changes than the original Fire Editor. This new save editor supports: Editing save files from any region and modded save files. Editing Chapter and Map save files. Editing unit data, including enemy units. Importing and exporting units between save files (including avatars, that are region-locked).
