Make sure that you have the necessary items. To play a video game file on your Nintendo DS, you will need the following items:
- Nintendo DS R4 card - Used to emulate a Nintendo DS game card. You can find these online or in some tech stores.
- MicroSD card - Storage for your ROMs. Try to find a microSD card with at least one gigabyte (1 GB) of RAM.
- MicroSD card adapter - A card that can plug into your computer's SD card slot. A card adapter often comes with a microSD card. If your computer doesn't have an SD card slot, you'll need a microSD to USB adapter instead.
- ' A ROM of the game you want to play - If you don't already have the ROM, you can find one to download by typing "[game name] from Nintendo ds" into a search engine. Only download ROMs from safe websites .

Insert the microSD card into the adapter. The microSD card should fit into a slot at the top or in the side of the SD card adapter.
- The microSD should only fit one way. If it doesn't fit, don't force it—just rotate it and try again.

Plug the adapter into your computer. You should find an SD card slot on the side of your computer (laptop) or on the computer's CPU box (desktop). If you don't, you'll need to use a microSD to USB adapter.
- Modern Macs don't have SD card slots, so you'll need an SD card to USB-C adapter.

Just like the microSD card, you should find a small slot at the top of the R4 card into which you can insert the microSD card.

Press the DS power button to do so. Due to the SD card, your DS may take longer to start up than it usually does.

Can you play Gameboy games?

Community Answer

No. You can only play DS games. The screen shots are also wrong, since it shows a 3DS game.

You can't, you can only play DS games, but I imagine you could use a laptop with some emulators.

Question

If I eject the cartridge while the folder is in the DS already, will the ROM still be there?

Community Answer

It will be there, the only problem will be that it will either crash or freeze your system.

It's best to have at least one gigabyte of storage on your microSD card, as doing so will allow you to install between 10 and 20 games at once.
