I'm new to this. I bought an r4 ultra, came with akaio 1.8.1 works with most games. I have a violet firmware DS Lite. I want to buy an acekard because they have akaio 1.8.7 (I can play pokemon black and FFIII) Not sure which one to buy. Acekard 2.1 Acekard 2.i Acekard RPG Or another card. I am looking for strong compatibility with newer games. Where should i buy it from. I live in western Canada.
