First let me start by saying: Yes, I hit Search already and did my research My DSL is only about 2 days old, but so far I'm in love with the thing. I've read every review on the SLOT1 cards, and it's come down to DS One & Acekard 2. They seem like the best 2 cards out right now from what I can tell, but I know 10% of what everyone else knows about this stuff. My biggest concerns are... SLOT2? What is this? I need something for both slots? I need to flash my new DSL to be able to use whichever card I buy? I've been reading these forums for about 4 hours now, trying to educate myself on this stuff. Basically I just want to be able to play NDS games & GBA games. Past that, I don't even know what features I should be looking for. I'd appreciate some feedback, or if you could point me to another post by someone else asking the same question, I'd appreciate that as well Thanks in advance.
