Hello,
I want to try messing around with Nintendo DS, I'm looking into the R4 and homebrew stuff. Can anyone recommend a site that would have detailed tutorials/guides?

I want to be able to emulate: C64, SNES, Sega Mastersystem & Genesis on the DS. I keep reading about emulators that do this but can't find and substantial tutorials. Any help would be much appreciated. Thanks in advance.

Regards
