Recently I put a post on my electronics and business blog about emulation and how legal it is. Please read that post before you even  consider following this guide. Emulation is illegal if  you don't already own the games you are emulating. Here is the post. This particular guide will be done in a list format.

Guide To Video Game Emulation

1. Visit Doperoms.com.
   
2. Click on the link that says "Emulators."
3. Pick a console then download an emulator.
4. Install the emulator.
5. Go back to the home page of Doperoms.com
6. Search for a video game that matches the video game console of the emulator you downloaded.
7. Check and make sure the video game matches your console, then download it.
8. Unzip or install the Rom if needed and store it in the folder you want your games stored.
9. Open the emulator. Either click file or something along those lines then click load Rom/s.
10. Click on the Rom you want to play, And you've just emulated a game!

Warning! Video game emulation is illegal if you don't already own the game you are emulating. So make sure you own games before you emulate them. This guide is meant to teach you how to backup games you already own. Not to teach you to illegally pirate games.
