Runs well even on less powerful devices. The app is no longer updated on the play store as far as I can tell  more recent versions can be found on their website. As is the case with most emulators  don't install if you aren't computer literate. The majority of negative reviews are by people who don't have a clue what they're doing. Also  buy an external bluetooth controller to play. Seriously  don't complain about on screen controls - that isn't the way these games are meant to be played.
