I am rating this app as a full 5 out of 5. I started with the lite version alomng with 3 other snes emulators. this one is by far the best - loads of control settings so you can figure out what works best for you. I recently decided to buy the full version - my first purchase in fact! I had some trouble installing this but this was in the end down to me, the developer David, talked me through and helped me get it all working! Top communication top app would highly recomend to every one!! Cheers David !! Keep it up !!
