Im using the actual card on emunand mate. I know the emunand is using the old keys. Just asking if they cant just use these keys on datel..
Likely not; -- if it were somehow possible -- they are incapable of detecting what type of savetype the cart is on your side and would end up clogging their own setup when the game-save doesn't decrypt. Hence why it's not.
The whole gateway/flashcart userbase is miniscule relative to the legitimate playerbase; they're focusing on getting as many people to buy their product.
