NES Remix Pack (Famicom Remix 1+2 in Japan) is a retail compilation of both NES Remix and NES Remix 2, released in 2014 in Japan and North America. In Japan, it was released alongside the digital release of NES Remix 2 while in North America, it was released alongside Ultimate NES Remix.
Outside of the additional title screen to choose which game to play, the game is functionally identical to having both NES Remix games installed on your Wii U, even including the Nintendo World Championships Remix in NES Remix 2.
When the game launched in Japan, it sold 11,079 in its first week. In North America, the game sold about 130 thousand when combined with Ultimate NES Remix.
