After it had been lying in a drawer for the past couple of years, yesterday I switched on my DS lite. Now, I have an R4 cart like the one shown in this thread which I recall purchasing sometime around 2009-2011. I have always used cheap SD cards with it, but so far they have always worked; that is, except for the fact that it took a bit longer to save than it was supposed to, i.e. if I switched the console off right after saving, without waiting for a couple of second, the save would probably end up being corrupted. The only major issues I've ever experienced with it where the following: - Castlevania Portrait of Ruin would always freeze when talking to Wind for the first time (sometime at the beginning of the conversation, sometime a bit later on). - Pokemon White would work, but doing everything that required loading, like entering a house, would be painfully slow. Now, if I bought this Kingston SDCH class 10 card, would those issues be likely to go away?
