I don't know if you have a Slot 2 cart, but if you do this is possible. Download Chishms "cart save" here: http://chishm.drunkencoders.com/SendSave/cart_save.zipThat's an interesting question. I don't believe there is any homebrew that'll let you do that. I guess most people don't see a point. To use a GBA ROM you'd need a GBA flashcart and most carts had a reader that could dump ROMs anyway.
True, but I'd like to know if this is possible too. I like to backup my original games to roms. I already did this with my DS games, but I still have a library of GBA games that need to be backed up...
aww
i wanted to put my emu fire red save on my real cart
