The new MasterGear-Android 2.8.15 adds automatic recognition of some games requiring special hardware, such as Codemasters´ MicroMachines and the MLB Baseball games. I have also split the Settings into multiple tabs, for easier navigation, and moved some of them around.

MasterGear-Android is my Sega MasterSystem, GameGear, and SG-1000 emulator for Android. You will find it here:
