Found a problem, it's only allowing 1 direction key at the moment to be pressed so you can't get those smooth movements which is crucial for enjoyable gaming. So you cannot first press down and then press down and right after and then release down button to move in right direction for example. With this plugin it won't work.
Also I noticed switching save states would switch it 2 steps when both pad1 and pad2 are selected as megapad, an option to "disable pad2" within the plugin would be good.
