4 stars: Tried using it with the Sonic 2 Nick Arcade and Simon Wai prototype, and I've gotta say-- it's pretty good. Other than the fact that you can't switch between p1 and p2 plus the fact that there's ads everywhere.
3 stars: It is decent, but needs some tweaking for how ads are displayed. Some ads are meant to be displayed upright and the app automatically displays them in landscape mode preventing you from skipping the ad at all. This costs unecessary uninstalls whereas if it is fixed more ads are viewed and the author would increase revenue with such a simple fix.
5 stars: This the best app for sonic games at least you can report the ad to skip it because some ads won't let you skip it but this is the best
4 stars: i love this is emulator. the problem i had was when i beat sonic 3 and knuckles it erases my data in a few days but although it still does it i get to load my last save state and my data which is better. But still I dont want my data to be erased.
4 stars: Pretty darn good and my go-to MegaDrive emulator. Loses a star because it's not quite as feature-rich as some other ones. Would be nice to be able to mute/reduce volume of the in-games sound so other apps could play over the top of it. Also, the screen only sits one way, so if you prefer another orientation, then you can't flip any other direction. Good overall, though.
3 stars: This emulator is good but the quick save is broken fix it then 5 Stars
5 stars: The best emulator ever, I ...
