In Android MAME 0.78 is available for download in the integrated Updater. But that version crashes whenever you try to load a rom.
Using this archived version of the core of MAME 0.78 works correctly: http://buildbot.libretro.com/stable/archive/stable/android/armebi-v7a/1.0.0.2/cores/mame078_libretro_android.so.zip This version only crashes on some games if you enable the rewind before load a rom, works ok if enable the rewind when game is running.
I think it would be interesting to fix the integrated Updater version, or replace it with the version I linked.
