There's ALOT of info on here. I am getting lost in all of the information, so I'm going to ask for help. I have an old brick DS. I want to use one of these devices for it, but I'm not sure where to begin. Is there now a device that uses only 1 card or something, or am I mistaken in this? Can more than 1 rom be saved on a card? I'll post necessary info, but I don't know what that info is, I just need a tad bit o help getting going. If you can post links to reading material that is more specific that'd be cool. I find that alot of the material is very general, except for the reviews, which are really good. TIA.
