3DS GBA Save Backup and Restore with GodMode9

Hello!
Thank you for the tuto!
I tryed with some CIA version of pokemon RFLG and it worked but with my emerald version i cannot restore my save. I mean i did all you said but it's still the same save from before. I tried many things but i couldn't find why it doesn't work.
Could you help me please?

Regards

 

Thank you for this!

 

Sorry the necroposting, but i had a huge trouble.
I had 2 pokemon games in my console: Pokemon Ruby and Pokemon Emerald. Who i inyect the Emerald save without that save affects my Ruby save?
I try to inyect the save between the Godmode9 method but when i start the Ruby game i got "save deleted" error and when i inyect the Ruby save to fix that, the Emerald save screw complete.

 

OH THANKS, MAN!

 

hi I try to inject my mgba .sav file to my 3ds using godmode 9 and it says injection failed.
I looked at my .sav file properties and it shows the size is 128kb but the size on disk is 132kb
Is that why I can't inject my sav file to my 3ds? and if it does how to rectify this problem

 

How would you load the rom onto an emulator to use the save? Could I just get a rom and rename it to the title ID?

 

Halfway through exporting/injecting save files for Pokemon Emerald I've been getting errors injecting the save files back in.
Here's some info:
- I modded my 3DS 2 days ago with the latest resources (gm9 and others)
- It worked at the start (had it exported on PC and added Old Sea Map back on the 3DS save file)
- If I try injecting a save file that I just dumped it'll tell me the injection failed
- I new game'd and tried again
- PKHeX with the WC3 plugin can still load/edit the file, but it's seen as invalid by WC3Tool.0.1e
- File size is 129KB (128KB on gm9)
- File name is: 0004000000017E00.gbavc.sav
- SD card is stock 4GB

 

So it won't let me continue from the save even though I get the message at the start saying it loads the battery from it (set it for 128kb saves).
I can play from the save on mGBA though so I saved and tried to restore that, still failed.

 

Hi, just registered for this forum to share how I fixed this issue after some flailing around on Google without confirming any hard solutions anywhere. For me, I dumped my save from a FireRed romhack with gm9 and played it on my PC with mGBA with no issues. However I was getting the inject failed message with the save file from my PC. Seeing haryor's comment earlier in the thread made me think of using a hex editor, so I opened up both saves for comparison and saw there's an extra 16 bytes at the end of the mGBA-associated save for some reason. (There's a block of FFs from 0001C000 through 0001DFF0 in both saves, so I figured the 'extra' set was at the end.) I deleted those 16 bytes at the end using the hex editor and saved it, and the inject with that save worked fine! So I think that solved it for me. After editing, the saves are both 131072 bytes long according to the editor; before editing, the mGBA one was 131088.

TL;DR:

• .sav from mGBA had 16 extra bytes at the end of the file causing failed inject error
• Used hex editor tool online to delete those 16 extra bytes
• .sav inject then worked just fine with the instructions provided upthread by InsaneNutter
