ndsi-savedumper VS Guide_3DS

First, follow dsi.cfw.guide to get homebrew setup on your DSi (you must install Unlaunch or it won't work). Then download DSi save manager and use that to dump your save file. Then you can move it to your PC via the SD Card

For DS (Requires flash cart)For DSi (requires Modding)For 3DS (Requires Modding)

Restore that edited save file to your game using savedumper.

Just to add to this, there's also ndsi-savedumper. It's no longer in active development, but you can get it here: https://github.com/edo9300/ndsi-savedumper

You can use a savedumper (https://github.com/edo9300/ndsi-savedumper) for dumping and injecting saves from and to legit cartridges. If you're playing a gba game on the DSi, you will have to install GBARunner2 (https://github.com/Gericom/GBARunner2) in order to run gba .rom files. I'd try placing your .sav file next to your .rom file and naming them like this: "{filename}.rom" and "{filename}.sav", where the {filename} part is identical.

I recommend modding the 3DS. Only because it adds so much features that the 3DS doesn't have now. On top of that, backing up the ROMs for your cartridges is great for long trips where you really don't want to bring every game you own, or just when you can't be bothered.
