What MAME core is necessary on Android?

[azorean]

Hi. Is it possible to run MAME on RetroArch Plus (Android)? If so what is the core to use? Or is there any other better MAME emulator that would work with my MAME 0.251 set? 

Thanks

Retroarch is an irritating mess. Here's what I did to make Mame work. 

Choose Retroarch plus as your emulator under LB. Choose the setting in the same screen to "Open Retroarch Plus". Install every core that says Mame. 
Exit Retroarch and under LB set the default core to mamearcade_libretto_android.so
