GB & GBC emulator for Android has been updated. Changes:
- support all possible Android key maps. Note: you must re-configure your keys due to config file changes;
- pause game if active behind another window;
- auto save-states can be saved after 15/30mins;
- GPU Sync Hack option to work around broken OpenGL drivers on some phones. Only enable if you experience OS lock-ups;
- increased the bounding box size for the fast-forward on-screen control.
