Overall, this is a very good emulator. I use a Razer Kishi and many games play well. My biggest gripes are with accessing the Atari console keys (Start, Option, etc.); they are near impossible to access: not only do you have to touch the screen just right, you usually get the drop-down menu instead. And there needs to be a way to map any attached controller input to any Atari input (keyboard, console key, joystick button) because some games require keyboard inputs while playing.

This works excellent. The only downside on the version i use is the real tiny menu you need but only pops up if you touch the upper right hand corner. Then you need to touch the upper just right of center area to get another menu you need to browse files but its not as small.

It's a pretty good emulator although it's not great for games with more than two disk images. I tried playing Ultima IV but it won't recognize the other files even though I changed the names according to the instructions in the help section.
