Game Boy Advance
From Nookipedia, the Animal Crossing wiki
The Game Boy Advance, often just GBA, is a 32-bit handheld system, the predecessor to the DS. In the GameCube version of Animal Crossing, it must be connected to the GameCube or Wii in order to do Advance Play with the NES's, to gain access to the Island in Animal Crossing, and to make patterns for free.
