My ak2i has been having some contact issues as of late and I've been looking for a solution to the problem. Then I came across this. http://www.ndscardsale.com/product/Acekard...Si-NDSi-DS-Lite If you take a look at the pics, the cart has teeth and a Green PCB. Now from what I understand about flash carts, teeth = less chance of contact issues. Should I go ahead and pay 12$ to try it out? A contact issue-less AK2i would be a dream come true.
