Is there a tool or (dev kit) out there to move game saves back and forth from a Gameboy Advance cart to a PC? I want to backup my saved data from the cart and be able to write saves to it. I want it to be in .sav format also. I have 20 games including Donkey Kong Country 1, 2, & 3 that need to be backed up soon. I looked online, but those flash/dev kits don't save info from a cart.
