Homebrew(through Steelhax), and Save Manager (for 3ds games). The nintendo update is 11.8.
UPDATE: I think it is because unfortunately my heartgold is a bootleg copy (damn you ebay!), cause fire emblem, it worked fine.
I get a black screen with TWLSaveTool 1.1 by TuxSH at the top and nothing else. I have heartgold in the gameboy. I have to restart to leave the screen.
Anyone seen this?
