It is truly just like having the real game. This emulator makes you believe that you are in an arcade. It is a REAL winner. The author, Peter Hirschberg, has done an outstanding job. So far, he has focused his efforts on some classic Atari games.
Most emulators can emulate a number of games.
Well, so does the author. The sights, the sounds, and the smells. Peter plans on lavishing each emulated game with the attention to small details that it deserves. Take a look at the detail of these games. Asteroids Deluxe and Battlezone both have the overlays that were present in the original game.
