A free program for Android, by Tom Cat L.

Mame Emulator Box is a free tool for Android that allows you to install the most common types of games from the 1980s and 1990s on your phone. It is based on the MAME project, which is an open-source multimedia arcade system and library.

The main focus of this tool is to make the life of gamers easier by allowing them to play their favorite games on their mobile phones. With this emulator, you will not have to download a bunch of files to play, nor will you have to use a lot of RAM. The emulator will make the process much easier for you. 

If you have never used an emulator before, you will not know what to expect. The most important thing to keep in mind is that the emulator will work on most Android devices.
