Topic. I have a DStwo with a 4gb class 4 sandisk microsd, and have no problems playing most games. However, my 4th gen Pokemon games (Platinum, Heartgold, Soulsilver) are extremely laggy. When I start a new game they're fine, but after a while (when I progress a certain distance into the game; it started around Olivine City in HG I believe) there will be lots of lag in the PC, the bag, before and after talking to NPCs, during loading/transition screens, etc. which makes it very annoying to play. I can understand why my Soulsilver lags as there are several hundred Pokemon on it, but the other two have literally ~10 Pokemon total and still lag like crazy. Does anyone else know of this problem, or have a similar problem? I asked a friend who also has a DStwo with a 4gb microsd of a different brand, and he said that his game only lags when he goes into the bag/that the problem might just be with my microsd.
