A SNES emulator is a kind of tool that allows you to play older Nintendo console games on your modern computer without buying the new versions. SNES stands for Super Nintendo Entertainment system, and it was released in Japan in 1991. It was one of the first home consoles to incorporate the chip that is used in modern gaming consoles, but because it was an advance in technology, it was expensive for the general public. Nintendo eventually released the nSNES, or the North American version, a year later, and it was a huge hit.
Because of its popularity, you can now find a SNES Emulator for almost any system out there. SNES emulators allow you to use your old console to play the older games you have always wanted to play. It is a great way to enjoy all the classic Nintendo games on your Wii, or on your PC. SNES emulators have been created for almost every game that has a cartridge. If you have a PS2, you can get a SNES adapter so you can use those cartridges as well.
Not all retro games require an emulator. There are many emulators out there that are made specifically for this purpose. Some are free, and some cost money. If you are looking to spend the money, you should check out Sonic Youth's" Chao Regeneration" project. It allows you to play the first level you want in Sonic, complete with all the background music from the game. The price is very reasonable, and you will not regret buying it.
