Any nds homebrew operating systems?

i know of DSision and YSmenu but neither work for me so are there any others?

Inferno DS http://code.google.com/p/inferno-ds/
Bricks OS http://code.google.com/p/bricks-os/
SunDev OS (the one i really want) http://code.google.com/p/sundevos/
indsos http://code.google.com/p/indsos/

DSLinux - http://dslinux.org/

dang i forgot that one lol

ok this is a stupid question, but if I want to play homebrew games do I need these? uh... you know sorta like how I would need SNES ds emulator to run SNES games?

No. Homebrew games should work on any DS Flashcart without an OS on it besides the Flashcart's firmware.

thanks for the help guys :)

No problem
