No, only SNES ROMs work on SNES. You need a NES emulator to run NES ROMs.

A Nintendo NES emulator is a game console. One could use this item for gaming or entertainment purposes. Depending on the game, one could also use it for educational or learning purposes.
You get a nintendo. You play it with an NES.
Basically a R4 card lets you play homebrew applications like a NES emulator which lets you play NES games.
No. Snes9x only plays SNES ROMs. You would need another emulator, such as Nestopia, to play NES games.
You don't. It only works on the Wii, Xbox 360, or the PS3
Emulators are a software emulating another computer. For example, an NES emulator is a software that is ran on a desktop PC to look like the NES (Nintendo Entertainment System), whereas you can play NES titles (Cartridges emulated as ROMs) using your keyboard or a controller for the NES controller. However, emulators are not just for other computers. Technically, an emulator is a piece of software that allows foreign (different language or setup) hardware or software to interact with the current system. The NES example is a good one. An example with software is like installing windows software on linux. It cannot be done due to language conflicts. An emulator solves this problem.
