So what happens when there's no more room left on the 3DS menu?

I ask this because I just downloaded the 10 Nes games for the ambassador program.  When I get the 10 free Gameboy Advance games, there isn't going to be too much space left on the menu.  I have an 8GB SD card in my system and I doubt it's even 10% full, yet.  Will I have to start deleting stuff?
