ABXY is a Super Nintendo Emulator for Android devices.
I tested several games and all played well with excellent sound and smooth graphics.
This "lite" version only allows 10 Saves before you lose the feature.

The only issues with this emulator are that the auto scan feature does not appear to recognize external SD cards.
There also appears to be no easy way to exit games. I had to hit the "home" button to exit a game.
