The emulator will load any ROM that you have stored in your device's memory. The formats .n64, .v64, and .z64 are all compatible with Muper64 Plus AE, and you can even access a video game saved within a .zip file.
Thanks to Mupen64 Plus AE, you can enjoy titles like Super Mario 64, Super Smash Bros., Pokemon Stadium, and Goldeneye 007 on your Android. The control system is the main problem you'll have when playing, but in some cases, it actually works quite well.
Graphically, the majority of the games have the same quality as in their original version, and in some cases - like Mario 64 - it's actually better.
Mupen64 Plus AE is a powerful, effective Nintendo 64 emulator that has a good compatibility list and is, of course, totally free.
