Homebrew Question about GBA saves

[Jacob91x]

I have a question regarding whether or not it's possible to place a physical GBA cartridge in Slot 2 and then load a .sav file that is saved on the R4 onto the game in slot 2. If there is any way to do this I would much appreciate someone pointing me in the right direction of figuring out exactly how.

You can use http://gamebrew.org/wiki/GBA_Backup_Tool to copy your save into the cartridge but it will erase the one which is in .

Try running it from root if you have problems.

How would I take a .sav file and put it on the cartridge? It's straightforward enough to extract the .sav, not so much to replace it with another. Can anyone help explain exactly how to do that? It's a bit confusing to me the way it's laid out.

For some reason when I dump the ROM it doesn't load up on VBA. Also, it seems that the save game I'm trying to use for pokemon emerald is 64k but the save game on my cartridge is 128k.. therefore it won't allow me to replace the save file that I am trying to. Any suggestions?

Looks like you have a pirate copy, these usually have different size saves, and dont run in emulators. Google a guide on how to find out if your game is a pirate one, and check it out.
