I found this site called 1980 games about a year ago. This site features 1980's arcade games, NES games, and flash games based on popular franchises, like Final Fantasy. I'm suprised at the NES games they have. They have most NES games that have been made, but they also have bootleg games and japanese games that have been fan-translated to english!Best of all, you don't need an emulator! You can play the games right on the site with a browser emulator called NesCafe. You just click on the game you want and start playing! This is the same with the arcade games too. Anyway, here is a link to the site.
1980 games I play games. I like games. I live for games.
