Im a total DS noob PLEEZ HELP ME!

[crackkills]

I just got a ds and a supercard sd, how do i play homebrew and whatnot. My friend had the same thing and he got it already hacked, so he doesn't know. I tried to put some homebrew on it and it didn't work. On the replies someone asked "No supercard support?" how can i get our DS's to play homebrew and roms for mine(my roms by the way, I own the cartridges)

Do you have a pass key

[crackkills]

what is a pass key

[crackkills]

his ds plays mp3s, videos, and roms(gba and nds) so i don't understand why it wouldn't play n e thing else

Sounds like his DS is flashed or he's using a Passcard v3 or Superkey in the DS slot at the top.
You obviously don't have a flashed DS or do not have a Passcard v3 or Superkey in your DS Slot at the top.
