Wait I dont understand. I went to the downloads section of the SuperCard website and there are so many to choose from. If I go for the 3DS supported firmware will this work on my DSi as well? Also with this update would I be able to play this Kirby game without having to do any patch work on it?For supercard dstwo, you should have the latest EOS and patch from the official site. Easiest way to play it is just get the prepatched Rom. Google is your friend for that.
Do those 3 things and you should be good to go.
