Custer's Revenge Online?

Have you ever played that old Atari game Custer's Revenge?
I used to have it in my old videogame console. I remember playing Custer's Revenge all day long, sometimes I wouldn't go to sleep and stay playing the game.
I was so addicted. Is the game online?
I want to play using my web browser, is Custer's Revenge online?

Custer's Revenge (also known as Westward Ho and The White Man Came) is a video game made for the Atari 2600 by Mystique, a company that produced a number of adult video game titles for the system. The main character was based on General George Custer.

Custer's Revenge remains one of the most controversial and bizarre games ever released. The object of the game is to guide General Custer across the screen while avoiding incoming arrow fire. Waiting at the other side is an Indian maiden, and you earn points by… scoring. The slogan of the game was something like "When you score, you score!"

The game is not online, you have to download the rom and an emulator if you want to play it.
