The R4 3DS card has very good compatibility. It not only works on Nintendo 3DS (includeing the latest 3DS V4.1.0-8 E/U/J system), but also run well on Dsi/DsiLL/DsiXL and DS Lite. With a R4 card in hand, you can do a lot of things out of the box. Such as Play DS games, download demons from download stations, chat with friends in the same room, play music, videos, read E-book and so on. The new R4 3DS card has all function of old R4 DS card, it offers more compatibility and better stability. It is easy to mod Nintendo 3DS console with the R4 3DS flashcard.
There are many r4 cards for 3DS in the market now. Some are good in function and compatibility, but others are fake or bad in firmware update. Kindly recommend to buy the R4i SDHC 3DS or the R4i Gold 3DS card, which are most popular currently. If you want to avoid trouble, you can also buy a MicroSD card together, and ask the reseller to install the software and games for you. If so, after get the R4 card, you need to do nothing, but play games straightly. In other case, you already have MicroSD card in hand, and only take a r4 card, so, you need to install the r4 kernel and games by yourself.
Mostly, the r4 card will come with a USB adapter, it is for r4 kernel and game installation.
Each R4 card use it’s own software, it can be download from http://r4town.com/pages/Download-Kernel.html or the official website. After download, it is a zipped patch, which can’t be use directly. Users need to unzip the patch into some files.
Download the favourate games from: http://r4town.com/pages/R4-Rom.html to the computer. It is also a zipped patch. Unzip the patch into “.nds” file. Only the “.NDS” file can directly run on the r4 card. There are many other free website for DS game download, such as r4-roms.com. Players can choose any of them for R4 game download.
The R4 comes with a microSD to USB adapter which is very nice. If you have a memory card reader, use the SD adapter that comes with most microSD cards. In a pinch, put the memory card in a compatible phone and connect the phone to the computer.
Copy all unzipped files of R4 kernel and the game to the root directory of MicroSD card. Don’t bulid any mother directory, all files must be on root directory. If there are any other files in the MicroSD card, delect them, as they may case problem.
That should be all it takes. Remove whatever game may be in your 3DS' Slot-1, insert the R4 card, and insert the microSD card into the R4. There is only one way it can go, and it will most likely be the way you don't expect. It does not matter in what order you do this - you could also put the microSD card into the R4 and then put the R4 in the 3DS. (it is no good to take out the R4 card before 3DS power off)
You should get the safety warning, but before you get a chance to touch the screen to confirm, the R4 should take over. The default 3DS menu, if it was enabled (it is by default), will be bypassed, and the R4 menu will load. You will get three choices. The first one, Game, will allow you to load a .NDS file (a DS ROM, or a homebrew application - .NDS is to your DS what .EXE is to your Windows computer). The second one, Media, will allow you to play multimedia - music, video, text - using the Moonshell OS. The third one, Slot-2, will allow you to boot a Slot-2 (Game Boy Advance) game.
