Excellent Emulator! Its working great on my Moto G 1st Gen  and my Acer Iconia A500 and my two kids Hisense tablets. Currently playing Power Stone with no lag what so ever. I will try other games later on today. But for the people that are having trouble  you can put the games on the external SD card like specified but the bios won't work from the external SD card  you have to put it on the internal sd for it to work! Everyone  good luck  and that worked for me! Try it and it should work for you as well!
