The R4 DS is a slot 1 DS flash kit designed to play ROMs. I may be stating the obvious here, but the point is; that’s what it’s meant to do, and it does it very well. Often time’s people are confused on how to properly setup the R4DS, and that is what I am here for.
You will first need to go to the R4DS.cn website and download the latest firmware available. The latest version currently is V1.18. Save this somewhere on your computer for now. Now you need to insert your micro SD card into the micro SD card reader that is included in the package. Now plug it into a USB port on your computer. This is often not necessary, but you can format the micro SD card as well using FAT32.
Drag and drop the four files from the English (V1.18) that you downloaded in the previous step. Now you can drag and drop any .nds files onto your SD card reader. You can also transfer mp3 files if you would like to.
Remove the micro SD card reader from your computer and then take out the micro SD card. Insert the micro SD card into your R4DS cartridge, and then place it in Slot-1 of your Nintendo DS
Turn on your Nintendo DS. If you did it right, it will say loading, and soon after you will be presented with the R4DS UI. If it gives you an error, then you did not transfer the V1.18 files over correctly. Go back to step one and redo it.
Now that it is completely working just find your game or MP3 and play it.
How do I play GBA games?
First you will need a GBA Expansion Pack. The Ram Expansion packs will not work. Not all GBA Expansion Pack’s are compatible with the R4DS. The built in slot2 loader for the R4DS isn’t very reliable. I suggest doing a Google search in order to find an alternative. Be sure to do plenty of research before you buy something.
What is the largest micro SD card the R4DS can support?
The largest you can purchase is 4GB. The R4DS does not support the SDHC standard, so make sure you purchase the correct kind of card. A 4GB micro SD card will set you back around $10 is you know where to look.
How do I know if the R4DS is broken?
There are some common signs. A major one is if it takes more than 30 seconds to load the R4DS GUI. Another is if the R4DS will not play any ROMs. Make sure you have the latest kernel for the R4DS (V1.18) and that you installed it correctly.
Can I play NES or SNES games as well?
Yes you can, but that is only if you have the proper software to do so. Doing some research on your own will net you the results you want.
