Not sure they have flash cards for DS.
Reply:There are 2 items that you need to buy to be able to play downloaded GBA game roms from the internet. You need to buy a SD card adapter for GBA, and an SD card.





The SD card is where you store the roms.





The SD card adapter for GBA is the "alternative" solution to a proprietary format by Nintendo. Reading between the lines... it enables consumers to download rom copies of full commercial games, for free. Thereby saving you money.





There are many brands and there are many ways to play roms on your GBA. I recommend the "SUPERCARD" http://www.supercard.cn/. Its called supercard but its not a card, its an SD card adapter.





1. Buy the "Supercard"


2. Buy an SD memory module, the bigger the more games you can put inside. I have a 1gig card.


3. Download roms at http://www.grn.dl.am/


4. Copy the downloaded roms to the SD memory module using any card reader/writer you have.


5. Insert the SD memory module to the "Supercard"


6. Insert the "Supercard" into your GBA


7. "Power on" your GBA and you will see a menu of all the games, select a game then play it.





P.S. the supercard comes with a PC program that processes the ROMS. You need to process the roms before copying to the SD.





Have fun
