is there a program that allows you to copy ds games?

You have to use a external ds cart reader of some sort, but its not available to the public.

i always wanted to know, not released to the public? then who are the people that are ripping and allowing people to download it?

if not the "public"...they are the "private". duh.

my cousin has one he bought while he was in japan so the public can get them if you know where to look
