Ah, got it, I misread what they said, then. Not sure how I missed that right in the OP that says I need a donor cart.
After reading up on it, the save type of the donor cart needs to be the same as the one I wanna play, right? How does one (like me) know if the donor cart has the same save type? I do have a DSi-enhanced game cart or two lying around that I could borrow from my niece from time to time, but I doubt it's a guarantee of having the same save type... Sorry for the noob questions, I didn't think it'd get as deep as this to get one game working for me, but I am that determined to get it up and running.
