Hacking moonshell on ds fire link

[ches]

hey folks,
I have a problem... When I've putted moonshell on my ds fire link and I start the ds, it's just like moonshell isn't on the card. I just can't use it... I even don't see the map of moonshell...
please help me, cause I wanna put some music on the ds fire link.

thanks,
ches
