Sorry i am totally new to this. I have seen some examples on Youtube concerning putting nds roms on r4 ds and cyclo ds I have several questions concerning r4 ds and cyclo ds. What is the difference between those two? Do I just download a rom, place it into the micro sd, and run it via nintendo ds? Last of all, I live in Eastern US, where do i order r4 ds or cyclo ds?? I just do not know which one to buy.... All i need it for it to do is play roms that i have downloaded. thank you.
