How do I make ds codes? I have done some googleing but the only opton seams to be the datel trainer tool kit. But I rely don't want to buy some hardware if I don't have to, I also don't own an action replay card. Is there a way of making them with an emulator? or maybe some homebrew to do it? If I was to buy a the trainer toolkit, would I need an action replay device? Can I use it on my m3 simply or does it have to be with my real cartages?
