Well, what I mean is that the game isn't a retail game, but is made by normal people and written for the point of letting people not pay. For instance, *pulls out AceKard* DSOrganize. It's a homebrew DS game that is like a pocket organizer, or Lameboy, a GB emulator for DS. Those are examples. Also, I think there was a Doom port for the DS as well that is homebrew.
