Hi. I am a DS newbie here. Just bought myself a DS yesterday and currently enjoying it now playing New Super Mario Brothers. Then a neighbor of mine saw me playing the DS and told me there is a THING that makes the DS more enjoyable to play. I'm sure she said something like a super card or r4 or something. I am also I retro gamer and yes I admit I have a psp which I use to play games and retro games such as NES, SNES, SEGA Genesis, Gameboy, Gameboy color, Atari etc. I wonder if this super card can play these retro games too without any problems like slow downs or bad images etc. Ever since I heard about this super card thing, I wanna have one but I dont know what it is and where could I find it? I dont even know what it looks like. If this super card can play retro games like in the psp, please do tell me how to do itand what should I do to make it work. So to make the long story short, I wanna learn about the capabilities of this gadget and everything it can do on the DS. And ofcourse the assurance of playing retro games in the ds.
