got my first ds on black friday for $89. i assume its a normal fat ds. i have previously had gba with what i believe was a m3 card, that was several years ago. i still have the card if it will work with the ds. and that is my question, what do i need to do to emulate gba and ds games. ive been looking over this site for a while and cant find a "for Beginners" guide. thanks for any help.
