It really works without bios it's good app but there are problems that need to be fixed like. It's control transparency it won't let me change them but it's not a big deal. It's graphics is not that good little blurry. Pretty slow actually even without sound it's slow it's actually the main problem. But overall it's not that bad my phone is CM S5mini it's Android 6.0 low ram but emulators Should work in it's almost max speed and features cause it's an emulator if the problems are fixed I'll give 5 star overall
