Mame4droid

Mame4droid is a Mame emulator that allows you to play thousands of classic titles on your Android device.

Just as a clarification, the app itself doesn't include any games, but rather offers the ability to play them. That is, you will have to download the roms separately, which is not really difficult either.

The emulator controls are very precise for being on a mobile phone. That being said, you will need a relatively modern device, as it is more than likely that it will get a bogged down on older devices.

Mame4droid is one of those must-have apps for videogame lovers, as you can spend hours and hours playing some of the most famous games of all time over and over again.
