.DSN and .BIN

[afandjegudiel]

I don't know a lot about programming or hacking, and I'm sure this question has been asked before, but I can't seem to find the answer anywhere. So, please humor me.
Why can't you convert the .dsn files from a game cartridge to .bin files and save them to your system memory via sd card? It seems to me like that would work, since you can move DSiware games around like that. I'm sure there's a good reason, I just want someone to explain it to me.

It also occurs to me that I may have posted in the wrong place. If so, forgive me. I'm going to post this in the hacking forum as well.
