First of all, I would like to thank you for your hard work improving this emulator.

I have some suggestions, that are quite importan in my opinion.
In the game I often press and hold buttons Up + Left(or Right) and Down + Left (or Right) at the same time for controling characters. After realesing Left(or Right) but still holding Up button, the character keeps going. But when doing the same thing with Down + Left (or Right) combination, the charackter stops. Down button must be realesed and pressed again to move charackter further. This is quite inconvenience. It would be nice somehow to fix this issue. And mapping the same functions for several buttons would be quite useful too.

Best regards

P.s. sorry, if my english doesn't sound very naturally
