So about a month ago I bought a Acekard 2 for my DS Phat from a website recommended here (realhotstuff.com). It came in the correct box, everything was normal. However, since the start, it has had trouble getting many games past the title menu, and has had trouble saving certain games. It will not run simple and older games like Hotel Dusk, Contact, Rune Factory, and others. I now have a DS lite, and the troubles haven't gone away. Will they replace my kart?
