aFBA is a port of the popular Final Burn Alpha emulator to Android

aFBA has decent compatibility and game play is relatively smooth on more modern devices. Sound is a bit vibrato but not too irritating. I found the GUI to be a bit confusing but with trial error was able to figure it out. The on-screen buttons and stick are resizable and rearrangeable plus the emulator supports external controllers. Another plus is there are no ads.
