this thread seems to be a bit old, but I'll post in it anyway...
I am currently trying to get a Alpha Sapphire ROM working. I own the game legit and I extracted the header off of it using Gateway. I then injected my own header into my own game and it still doesn't work? I get an error saying I cannot use that game card online. I picked the game up where I left it on the actual cartridge (because someone here said you'd have to start the game all over again...)
Any suggestions left?
