Other consoles on NDS? (Wood)

Hi. Sorry if this is has been discussed. I've done a search, but couldn't find anything.I have an original r4 with the latest Wood firmware installed. Is it possible to play games from any of the other Nintendo consoles? GBA, SNES, etc...If there are any links to any tutorials, that would be great too. Thanks!

GBA : not possible unless you have slot 2 flash cart such as EZ Flash or use Super Card DSTWO
NES : Download emulator here--> http://filetrip.net/f25209-nesDS-0-51a.html
Just create a folder name NES ROM and place all your NES games in it. Not all NES game will work
as its still being continuously updated
SNES : Use SnemulDS --> http://filetrip.net/f3509-SNEmulDS-0-6-alpha-2.html. Again create a SNES
folder and place all the game in it. Not all will work as its also still being continuously updated
Atari : Use StellaDS --> http://filetrip.net/f25228-StellaDS-1-1.html. Still beta version, so not all will
work
Gameboy : use Lameboy --> http://lameboy.nutki.com/?p=24

Just google "SYSTEM X emulator for R4" and you will find a good one.
