Ive wanted to buy a new action replay for DSi since I play with my DSi much more than I do with my original DS and I need the compatibility. I need to understand something about different versions of action replay Ive come across that I need explaining. There is one action replay for DSi thats in a blue box and says it can work on all versions of the DS systems. Then I see a 2nd box, its black and it says action replay DSi Max. Is this somehow better than the blue boxed action replay and what differences do both of these have to each other?
