Homebrew Backup a gb save ?

[Deleted member 388618]

Hi,
I want to backup my pokemon yellow save from the original cartridge to put it in my 3ds. I have a gba linker and a gba. Is it possible to do this with à homebrew gba or something ? If not, what I need to do that ?
(I got a gbc, the game yellow, a New 3ds XL, à Nds lite and a Nds linker too)
Thanks you.

You can use Agbsave9 - a tool for dumping and injecting gba saves (or decrypt9 but idk how it work with this). Just google for it and you find a guide on tapatalk

Edit: My fault. I didn't read all. Yeah, first you need some extra hardware to dump your gba save

I doubt it's possible with what you have. You would also need a Mega Memory Card and a GBC flash cart.
Backup the save onto the memory card then restore it onto the flash cart. Followed by connecting the flash cart to a computer and reading the save from it.

That's what I did.
