I have not seen any, but that don't mean that they don't sell them at, say wal-mart, or target. they do sell them at GameStop.
flee markets, pawn shops, and second hand stores.
The Nintendo Wii utilizes a built-in "emulator" to play Nintendo GameCube Games, such as Super Smash Bros. Melee. On the "top" of the Nintendo Wii (if you use it in the included cradle) there are two doors. One of these doors covers the Nintendo GameCube controller ports. There are four of these. The other door covers the Nintendo GameCube Memory Card slots. There are two of these. In order to play any Nintendo GameCube game on the Wii, you need to use a GameCube controller, and in order to save, you need to use a GameCube Memory Card. You can still find both of these at most GameStop locations, and there are many stores that specialize in selling consoles, games, and accessories of the previous console generations. These stores seem to be mostly localized retailers, so these stores will have different names in say, Seattle, as opposed to, say, Chicago.
Yes, you can find this game used and NEW in gamestop and on online stores like, amazon.
Some video game stores and even antique stores will carry a limited selection of Nintendo 64 games. However, it is not possible to emulate and play these games on a modern PC.
Gamecube games can be purchased in a variety of places. First, Gamecube games can be purchased at brick-and-mortar stores (e.g., Game Stop, Best Buy). Second, Gamecube games can be purchased online through websites like Amazon or eBay. Third, Gamecube games can be purchased at thrift stores or used-game stores, such as Savers or Play N' Trade.
This is dependent on what model is desired, a Nintendo Wii, or Wii U can be purchased as a bundle at any electronics or department store. Older models such as Gamecube or Nintendo64 can be purchased at specialty game stores. The older models may come in a bundle, but it may not be an official Nintendo bundle.
Nintendo has stopped making new games for the gamecube. The last game they published for the gamecube was The legend of Zelda: Twilight Princess. All places that sell games will most likely have gamecube games just not very many new ones.
a Nintendo Wii is already out in stores
Both Pikmin 1 and 2 actually came out on the Nintendo Gamecube platform. It can somtimes be found in Game stores such as Gamestop and EB Games, in their "Pre-owned" section of course. Your best bet is online shopping/ auctions like Ebay.

some gamestop stores will. Many local video stores will as well.
You cannot buy an Action Replay Gamecube or GameShark for Gamecube anymore as they no longer support the Gamecube or its games and accessories, However, You can still buy these from Amazon, Ebay or possibly a pawn shop (Pawn shops sometimes have Gamecubes and Gamecube Accessories)
