WARNING: Decrypt9 added a native save dumping and injecting tool that works way better than AGBSave9, you can download it here. I'll be keeping this guide around for historical purposes, but you should use Decrypt9 instead. Depreciated tutorial here Dumping GBA VC saves:What you will need: AGBSave9 v.1.0 "EEPROM support" (A9LH-compatible version here) 1) Run the game that you want to dump the save and close it. 2) Load AGBSave9 from sysNAND 9.2/A9LH and select "Save Dump". 3) This should give you a screen with this info: Title ID: xxxxxxxx Use save type 0/1/2: SRAM/Flash/EEPROM Creating agb_dump.sav ... 4) Write down the Title ID and Save Type, you'll need it if you want to inject the save back later. 5) Plug your SD card into your computer and copy the agb_dump.sav on the root of the SD to somewhere safe, this is your save file. Injecting saves into the GBA VC:What you will need: The "agb_inject" folder from AGBSave9 from v1.0 "EEPROM support" This modified "gen_run.py" (Note: The gen_run.py included with AGBSave9 1.0 isn't working properly) Python 3 1) Install Python 3, else you won't be able to run the gen_run.py. 2) Copy your save file into the agb_inject folder. 3) Run gen_run.py and follow the on screen instructions, this should generate a .cia file inside the agb_inject folder. 4) Copy the output CIA file to your 3DS' SD card. 5) Install it on sysNAND using your favorite CIA installer, I recommend FBI. (if it asks to overwrite the previous install, allow it.) If you only have them on sysNAND: 6a) Run the CIA that you just installed. (It should show up as Fire Emblem on the top screen) If you have them on both NANDs: 6b) Run the game that you want to inject the save on emuNAND. 7) When "AGB_FIRM save injector" appears, turn off your 3DS. 8) Insert your SD card on your computer and go to "/Nintendo3DS/(YourSysNANDHere)/(RandomStuff)/title/00040000/(TitleID)/" and copy the data folder. 9) Reinstall the game that you want to inject the save on sysNAND. (if it asks to overwrite the previous install, allow it.) 10) Reinsert the SD card on your computer and copy the data folder back into "/Nintendo3DS/(YourSysNANDHere)/(RandomStuff)/title/00040000/(TitleID)/" 11) Run the game, if everything worked properly, your injected save should appear on the game.

Edits: 2016-08-10: Decrypt9 released an update with save injecting and dumping, there is no need to keep using AGBSave9 anymore. 2016-05-04: Hopefully fixed the formatting on mobile devices, added a emuNAND side note, thanks @AnalogMan 2016-05-20: Looks like AGBSave v1.0.1 has a broken "agb_inject" folder, while it's fixable, there is no difference between it and v1.0, and you still need a modified script to run, so right now, I'm recommending v1.0 over v1.0.1.
