MAME4droid Reloaded

MAME4droid Reloaded is developed by David Valdeita (Seleuco), port of MAME 0.139 emulator by Nicola Salmoria and TEAM. MAME4droid Reloaded emulates arcade games supported by original MAME 0.139. This MAME4droid version is targeted to Dual-Core devices (1GHz and 512MB RAM minimum), because it is based on a high specs 2010 PC MAME build.  For older, slower devices please use MAME4droid (0.37b5) from the same developer.

NEO.emu

Neogeo arcade and home system emulator based on Gngeo 0.8-svn (GPL), designed and tested on the original Droid/Milestone, Xoom, Galaxy S2, Nexus 7, and Xperia Play, but works on many devices with similar specs. It requires user-supplied romsets from MAME 0.144 or newer for correct operation (neogeo.zip, etc). View the full compatibility list here.

NeoDroid

Unfortunately the developer of this emulator decided to abandon the project. It’s a shame as it was working and was completely free. The links are down at the moment, and is no longer available at the Google Play store, but keep an eye on this Xda-Developers thread in case the author decides to resurrect the project.
