For anyone still interested in Awakening Character class modding in recent days :)

As is in the title. Here is what I use...

What you need; Luma3DS etc., Checkpoint, FEAST, Fire Editor 3

Guide to Install Mods (I used this one)-

 

Fire Editor- (Files are in this page) https://gbatemp.net/threads/release-fire-editor-fire-emblem-awakenings-save-editor.397493/page-142

FEAST- https://github.com/SciresM/FEAST/releases/tag/v1.1

1- Mod your 3DS to have Luma3DS and the works (At least have Checkpoint.)

 

2- Extract your Save file using Checkpoint. 

3-Insert your 3DS SD card into your Computer. 
 

4- Open FEAST/Fire Emblem Save Editor, then click on “Open Compress File.” Click into your SD Card files, go into 3DS, then Checkpoint, then Saves, then Awakening. Select your Save, then select Chapter 0, or whatever yours says, then click “Decompress File.”

5- Open Fire Editor

6- Click the folder button in the top right and select your decompressed save file.

7- Mess with your characters.

8- Save with the right button in the top right.

9- Open your Decompressed save file with FEAST/Save Editor, and Compress it. I delete every other file that isn’t the freshly compressed file to avoid confusion. 
10- Remove your SD card from your computer and put it back into your 3DS.

11- Open Checkpoint. Click A on new to get it to respond to you, and back up your save to Awakening.

12- Reap the rewards. Have fun!!

Might be better to link the thread about the editor directly rather than just somebody quoting the OP of that thread, but yeah, this is how you'd do it.

I know this is a bit late but the site no longer works on Chrome.
