In the '3ds' folder on the 3ds, you have the completed installed 3ds games.
If people uploaded these, instead of the cia file,
you could in theory just drop these folders into your sd card and they would be installed instantly.
Let me give you an example.
You install a game on your PC.
However, you could just go to the installed folder, copy and paste it, and use that instead of installing it every time.
would this work ?
