can i download a gba game and play it on my ds?

i'm new at this so bear with me. does anyone know how i can play a gba game that i download off romulation on my nintendo ds? do i need anything special to do it? thanks in advance for any help. :)

you need a slot 2 flashcard such as an Ez-flash 3 in 1

I thought it was also possible to play GBA games on an emulator as well, I'm not sure if it works for the DS but it works on the computer.

There are GBA emulators for the PC, yes. And they work very well (nearly 100%)But there are no GBA emulators for the DS. In order to play them you must use the built in GBA support of the DS itself, which is only accessible from the Slot 2 (GBA Slot) of the Nintendo DS.

any idea where i would get the slot 2 flashcard or an emulator?

ebay-or try the site of ezy 3 in one.As for emulators, for the ds, I would use no$gba 2.6 (google it)...Google is your friend-use it to help-prehaps it may find a solution...But if you can't buy online (like me) then look around at your game shop where you got your ds flash card-just mention it and they can help...And emulators are free :) (unless the creators need money-but you can get free versions of all the emu's)

To get the latest no$gba version 'morally', you need to give a Donation to Martin Korth (developer).
