This is a video of me playing my Super NES Emulator on my R4 3DS Card on the Nintendo DSi and the Nintendo 3DS. The r4 3ds is from http://www.r43ds.org and the super nes emulator I am using is Snes DS. It's probably the very best Snes emulator available for all R4 cards and works on the DS, DS lite, Nintendo DSi, nintendo DSi XL and even the newest Nintendo 3DS and 3DS XL consoles.
I'm sorry for the big of a blur in the video. I am going to remake it with about 10 different games being played. My Flip camera was MIA when I made this video, but has now been found and I will be making more Super NES / NES / Nintendo 3DS and R4 3DS emulation videos.
The card I am using is the R4 3DS Red box version. While there are other r4 cards out there, I prefer to use this one as it seems to always get updated by the factory that makes them, so I have never had to actually replace the card like some of my friends have had to do with theirs.
It even lets me watch movies on my 3DS too, as well as run and use several other emulators that are available. Nes, Turbo Grafx 16, Neo Geo and many others. So it's not like you just have to play Super NES games... you can play lost of other cool retro games too.
