Setting up the Equipment

1
Buy an R4 SDHC card. An R4 SDHC card is the substitute for a game card when loading your own games on a DS. This is what you'll plug into the DS in order to load your downloaded games.
- The easiest way to find an R4 SDHC card that will work with your DS is by typing r4 sdhc nintendo ds into an online store's search.
2
Buy a microSD card. The microSD card is actually where the games will be stored, so try to find a two-gigabyte (2 GB) card if possible.
- You can find microSD cards online as well as in most tech stores.
- Most microSD cards come with an adapter that allows you to open the SD card on a computer. If your selected microSD card doesn't include an adapter, you'll need to buy one as well.

Plug the microSD card into the included adapter card. At the top of the microSD's adapter card, there should be a small slot into which you'll insert the microSD card.
- The microSD card only fits one way, so don't force it. If the microSD card won't fit into the adapter card, flip the microSD card over and try again.
4
Plug the microSD card's adapter card into your computer. There should be a wide, flat slot on the side of your computer (laptop) or on the CPU box (desktop) into which the adapter card fits.
- If you use a Mac, you may need a USB-C to SD card adapter.
5
Format the card. Before you can add files to the microSD card, you'll need to make sure that the card's format is correct:
- On Windows, select FAT32 as the file system.
- On Mac, select MS-DOS (FAT) as the file system.
6
Download a ROM for your selected game. A ROM is a game file; by placing these game files on your SD card and then using the card with your DS, you'll be able to select games directly off of the card. The easiest way to download ROMs is by searching for your game title followed by "ds rom", selecting a reputable site, and clicking the "Download" button or link.
- Keep in mind that downloading ROMs for games that you don't already own is piracy, which is illegal in most places.
- Make sure that you only download from sites that you can trust based on user feedback and reviews. You don't want to accidentally download a virus.
7
Wait for your ROM to finish downloading. Once the ROM for your game has finished downloading onto your computer, you can proceed with adding the ROM to your microSD on a Windows or Mac computer.
